The technical solution relates to radio communications, and in particular to methods one-way radio communication between mobile objects, routes which have a common starting point.

There is a method of satellite communication (see, for example, Owhali, Niestetal, Usarc, Hardon Aguilar. Radio communication. Edited Avelona. - M.: Hot line - Telecom, 2001, s-279), namely, that transmit radio signals from the first movable object, take these radio signals on an artificial Earth satellite, transmit the radio signals from artificial Earth satellite, receive these radio signals on the second movable object, transmit radio signals from the second movable object, take these radio signals on an artificial Earth satellite, transmit the radio signals from artificial Earth satellite, receive these radio signals on the first movable object.

This method allows a great range of radio communication between moving objects on the Earth's surface or near it, regardless of their routes, however, requires removal of radio communication satellites in earth orbit and motion control and operation, which complicates the method.

However, the considerable height of the orbits of satellites (from hundreds of kilometers in systems with low earth orbits to tens of thousands is ilometres in systems with high-elliptical and geostationary orbits - see, for example, Umoristi, War, Lamnidae. Future satellite communication systems. - M.: Hot line - Telecom, 2000, p.71) require on the space station and mobile objects transceiver devices with large capacity, equipped vysokonapolnennyh antennas.

However, increasing the power transmitting devices causes the deterioration of their mass and size parameters, decreased immunity of the various on-Board radio-electronic means, as well as the reduction of electromagnetic safety of people on mobile objects.

The above drawback in combination with disabilities create antennas with higher gain leads to an increase in the geometric space occupied by this system with radio (local coverage of the earth surface by a single beam satellite repeater reach hundreds of kilometers in diameter - see ibid, p.78-110), which reduces the efficiency of the method in the simultaneous operation of multiple radio systems.

The term “volume of geometric space” describes one of the three major (along with the bandwidth and time) components of the RF space communication system (see Naagin. Topical issues of monitoring in the Russian fed the walkie-talkie. - M.: Radio and communication, 2000, C.11-12).

There is a method of radio communication between aircraft (see, for example, Pascalidou, Paisano. The maintenance of avionics. The Handbook. - M.: Transport, 1990, p.88-92), namely, that transmit radio signals from the first aircraft, take these radio signals on the second aircraft, transmit radio signals from the second aircraft, take these radio signals on the first flying machine.

This method does not require solving complex problems inherent in satellite radio, and allows a great range of radio communication between aircraft performing flight at high altitudes on arbitrary paths.

However, the communication distance between the low-flying aircraft significantly decreases as a result of the influence of reflection of electromagnetic waves from the Earth's surface (see, for example, theoretical foundations of radar. Edited Vaitulevich. - M.: Soviet radio, 1978, s).

To increase the range of radio communication it is necessary to increase the capacity of on-Board transceiver stations and the orientation of their antennas.

However, increasing capacity on-Board transceiver stations causes the deterioration of their mass and size parameters, decreased immunity of the various on-Board radioelectronic funds as well as the reduction of electromagnetic safety of people on the aircraft.

The above drawback in combination with disabilities create antennas with higher gain leads to an increase in the geometric space occupied by the communication system, which reduces the efficiency of the method in the simultaneous operation of multiple radio systems.

Meeting the technical challenge is to improve mass and size parameters transceiver stations mobile objects, routes which have a common starting point, increasing the noise immunity of the various on-Board radio-electronic means, the increase of electromagnetic safety of people on the moving objects, the reduction in the geometric space occupied by the communication system, and, hence, increase the efficiency of the method in the simultaneous operation of multiple radio systems based on the implementation of the radio using discharged from the moving objects in low-intermediate transceiver stations, are equipped with omnidirectional antennas.

The solution of the technical problem in the way of radio communication between mobile objects, routes which have a common starting point, namely, who then passed on the specified operating frequencies of the radio signals from the first movable object, take specified operating frequencies of the radio signals on the second movable object is achieved by the fact that since the time of the first removal of the first movable object from a common starting point by a distance defined by the given ranges of validity radio station, located on the first movable object and the intermediate transceiver stations, the first mobile object shall reset the intermediate transceiver stations at intervals along the range defined by the given ranges of the transmitting steps and intermediate transceiver stations, since the time of the first removal of the second movable object from a common starting point by a distance defined by the given ranges of validity transmitting station and the intermediate transceiver stations, from the second mobile object shall reset the intermediate transceiver stations at intervals along the range defined by the given ranges of the transmitting steps and intermediate transceiver stations, and radio transmission from the first mobile object on the second movable object is that if the reset intermediate transceiver stations operate with both moving objects, you accept transferred from the first movable lens is the radio on the last reset with the first movable object intermediate transceiver station and transmit them accept transferred from this intermediate transceiver station radio signals on the penultimate discharged from the first movable object intermediate transceiver station and transmit them, in the same way carry out reception and transmission of radio signals using other previously discarded from the first movable object intermediate transceiver stations in the direction of transmission of the radio signals from the reset intermediate transceiver stations at a later time to reset to an earlier time points, accept transferred from the first discharged from the first movable object intermediate transceiver station of the radio signals at the first dropped from the second mobile object intermediate transceiver station and transmit them, accept transferred from the first discharged from the second mobile object intermediate transceiver station, the radio signal of the second reset from the second mobile object intermediate transceiver station and transmit them, in the same way carry out reception and transmission of radio signals using other discarded at a later time from the second mobile object intermediate transceiver stations in the direction of transmission of the radio signals from the reset intermediate transceiver stations in an earlier IOM is you time to reset at a later time, taken on the second movable object by radio signals are radio signals transmitted from last reset from the second mobile object intermediate transceiver station, and if the reset intermediate transceiver stations operate only with the first movable object, the receiving transmitted from the first discharged from the first movable object intermediate transceiver station of the radio signals is carried out on the second movable object, if the reset intermediate transceiver stations shall only from the second movable object, the receiving transmitted from the first mobile object signals is carried out on the first discharged from the second mobile object intermediate transceiver station.

The method consists in the following.

Consider a situation in which the first movable object 1 is a ground vehicle, the second movable object 2 is the low-flying litate the capacity of the apparatus, for example, helicopter, or airship.

The term “low flying aircraft” is generally accepted (see, for example, the Radio system. Edited by Prof. Umetalieva. - M.: Higher school, 1990, s). The second movable object 2, in particular an aircraft is flying at low levels, if the condition (see theoretical bases of radar. Edited Vaitulevich. - M.: Soviet radio, 1978, s)

where C is the speed of light; ha- the height of the first transmitting antenna 33 radio transmitting station 3, located on the first movable object 1; hb- the height of the first receiving antenna 34 a receiving station 4, located on the second movable object 2; d is the distance between the first mobile object 1 and the second movable object 2.

The expression (1) is true, if the condition of mirror reflection of radio waves from the underlying surface (see ibid., s)

where ψ - angle slip; δ - the height of the irregularities of the underlying surface.

For definiteness, let us assume that the surface on which the Ground surface is a mirror reflecting the horizontal plane, i.e. condition (2) is performed.

The first moving object 1 is moving only in the underlying on which ernesti.

On the first movable object 1 is placed radio transmitting station 3 and M intermediate transceiver stations 5 numbers m=1,2,... ,M, where m is a positive integer. On the second movable object 2 is placed a receiving station 4 and N intermediate transceiver stations 5 with n=1,2,... ,N, where n is a positive integer.

In the General case, the first movable object 1 and the second movable object 2 at each point of the reset can be reset on more than one intermediate transceiver stations 5.

Let us assume that the first movable object 1 and the second movable object 2 at each point of the reset discharge only one intermediate transceiver station 5.

Earlier time points reset intermediate transceiver stations 5 with the first movable object 1 are in the intermediate transceiver station 5 with lower numbers

where tntν - time reset n th ν th intermediate transceiver stations 5, respectively; ν =1,2,... ,N positive integers.

On the second movable object 2, the reference time tbconduct from the timeat which the second movable object 2 was in General the initial clause (1).

In General, moments in timeandcan not match.

Last reset from the first movable object 1 intermediate transceiver station 5 is an intermediate transceiver station 5, the discharge of which is carried out in the most recent point in time

where mmax=1,2,...,M

Last reset from the second movable object 2 intermediate transceiver station 5 is an intermediate transceiver station 5, the discharge of which is carried out in the most recent point in time

where nmax=1,2,...,N.

If the condition (2) the range of the m-th reset with the first movable object 1 intermediate transceiver station 5, except for the first discharged from the first movable object 1 intermediate transceiver station 5 (m=1), is determined by the formula (see the am, s-410, formula (14.10), (14.20), (14.30))

where Rm)- power radio signals transmitted from the m-th reset intermediate transceiver station 5; Pm-1 so minsome threshold value, which characterizes the sensitivity of the m-1 intermediate reset transceiver station 5; hmhm-1 - the height of the second transmitting antenna 53 m-th and the second receiving antenna 44 (m-1)-th reset intermediate transceiver stations 5, respectively.

The range of the n-th reset from the second movable object 2 intermediate transceiver station 5, except the last one dropped from the second movable object 2 intermediate transceiver station 5 (n=nmax), equal

where Rn)- power radio signals transmitted from the n-th reset intermediate transceiver station 5; Pm+1 so minsome threshold value, which characterizes the sensitivity of the (n+1)-th reset intermediate transceiver station 5; hnhn+1- the height of the second transmitting antenna 53 n-th and the second receiving antenna 44 (n+1)-th reset intermediate transceiver stations 5, respectively.

The range of the first discharged from the first movable object 1 intermediate priemoperedayuschie equal to 5

The range of the last discarded from the second movable object 2 intermediate transceiver station 5 is equal to

where- power radio signals transmitted since the last reset with the second movable object 2 intermediate transceiver station 5; Pb pminsome threshold value, which characterizes the sensitivity of the receiving station 4 of the second movable object 2;the height of the second transmitting antenna 53 last reset from the second movable object 2 intermediate pickup is peredayushii station 5.

The range of radio broadcast stations 3 of the first movable object 1 is equal to

where Rand [Izl]- power radio signals transmitted from the first mobile object 1;some threshold value, which characterizes the sensitivity of the last reset with the first movable object 1 intermediate transceiver station 5;- the height of the second receiving antenna 44 last reset with the first movable object 1 intermediate transceiver station 5.

Under the height of the antenna understand the distance to under the antenna point of the underlying surface.

In General, the height hathe location of the first transmitting antenna 33 radio stations 3 varies in the range of ha minto ha max. The minimum value of the height ha minis achieved when the first moving object 1 is located on an underlying surface, and is determined by the characteristics of the structures and layout of the first movable object 1 and the radio station 3. The maximum value of the height ha maxdoes not exceed the sum of the values of ha minand maximum flight altitude Ha maxthe first movable object 1.

In this case, the first movable object 1 is nazem the second vehicle, therefore ha min=ha max.

The height hb, the location of the first receiving antenna 34 a receiving station 4 is changed in the range of hb minto hb max. The minimum value of the height hb minis achieved when the first moving object 1 is located on an underlying surface, and is determined by the characteristics of the structures and layout of the first movable object 1 and a receiving station 4. The maximum value of the height hb maxdoes not exceed the sum of the values of hb minand maximum flight altitude Hb maxthe first movable object 1.

Height hmthe location of the second receiving antennas 44 and second transmitting antennas 53 is reset with the first movable object 1 intermediate transceiver stations 5 range of values of hm minto hm max. The minimum value of the height hm minis achieved when m-I intermediate transceiver station 5 is located on an underlying surface, and is determined by the design features of this intermediate transceiver station 5. The maximum value of the height hm maxcorresponds to the time reset m-th intermediate transceiver station 5 with the first movable object 1 and does not exceed the value of hm max.

Height hnthe location of the second receiving antennas 44 and second transmitting antennas 53 spose is different from the second movable object 2 intermediate transceiver stations 5 range of values of h n minto hn max. The minimum value of the height hn minis achieved when the n-th intermediate transceiver station 5 is located on an underlying surface, and is determined by the design features of this intermediate transceiver station 5. The maximum value of the height hn maxcorresponds to the time of discharge of the n-th intermediate transceiver station 5 from the second movable object 2 and does not exceed the value of hb max.

Expression (1), (2) and (7)-(11) are approximate and do not take into account the geometry of the first movable object 1, the second movable object 2 and the intermediate transceiver stations 5.

Considering the above, we assume that for all m and n fair equality

From expressions (7)-(10) it follows that under the conditions (12)-(15) the minimum range of the intermediate transceiver stations 5 equal

For given values of R[Izl], Rprminand hmintaking into account formulas (16) range intermediate transceiver stations 5 set equal

The range of radio broadcast stations 3 specify a given distance is awn steps intermediate transceiver stations 5, for example, by the formula

The routes of movement of the first movable object 1 and the second movable object 2 have a common initial point O.

In General, when the traffic on their routes, the first moving object 1 and the second movable object 2 can make a stop at arbitrary time intervals. In addition, in the General case, the first movable object 1 and the second movable object 2 can start moving on their routes at any timeand.

Assume that the first movable object 1 commits to the underlying surface rectilinear motion from a common initial point O, located on the x-axis (figure 1); the motion is constant velocity Vandalong the x-axis in the direction of in the direction of decreasing values of x; the maximum distance from a common starting point to a first movable object 1 is equal to da maxand characterizes the length of the route of the first mobile object 1.

The second movable object 2 exercises from the common starting point Of the vertical height hb maxand then performs a horizontal flight at a height of hb maxwith constant velocity Vbalong the x-axis in the direction of in the direction of increasing values of x; max the e distance from a common starting point to a second movable object 2 is equal to d b maxand characterizes the length of the route of movement of the second movable object 2.

Before time ta minfirst remove the first movable object 1 from a common initial point O, the distance da minand before time tb minfirst remove the second movable object 2 from a common initial point O, the distance db minno the first movable object 1 or the second movable object 2 reset intermediate transceiver stations 5 do not exercise. While the implementation of the method lies in the fact that transmit radio signals from the first mobile object 1, receive these radio signals on the second movable object 2.

The value of da minand db mindetermined by specified distances of Ra=Rm=Rn=Rminaction radio transmitting station 3 and the intermediate transceiver stations 5.

In particular, the value of da minand db minyou can set

where k11 - factor, taking into account the approximate nature of the applied formulas.

From the moment of time ta minfirst remove the first movable object 1 from a common initial point O, the distance da minthe first movable object 1 discharge intermediate transceiver stations 5 intervals in range, the determination is mined based on specified ranges of validity transmitting station 3 and the intermediate transceiver stations 5.

Effect of the assumptions interval reset intermediate transceiver stations 5 with the first movable object 1 can be

Reset the first intermediate transceiver station 5 with the first movable object 1 is carried out in a time ta minfirst remove the first movable object 1 from a common initial point O, the distance da min.

From the moment of time tb minfirst remove the second movable object 2 from a common initial point O, the distance db minfrom the second movable object 2 discharge intermediate transceiver stations 5 intervals range defined by the given ranges of validity transmitting station 3 and the intermediate transceiver stations 5.

Effect of the assumptions interval reset intermediate transceiver stations 5 from the second movable object 2 can be

where k31 - factor.

Reset the first intermediate transceiver station 5 from the second movable object 2 is carried out in a time tb minfirst remove the second movable object 2 from a common initial point O, the distance db min.

Distances from obseg the start point to the first movable object 1, which discharge the intermediate transceiver stations 5, can be measured on the first movable object 1 using inertial or Doppler systems reckoning (see Aeronautical radionavigation: a Handbook. Edited Ass. - M.: Transport, 1990, p.6-8).

Distances from a common starting point to a second movable object 2, which discharge the intermediate transceiver stations 5, can be measured on the second movable object 2 using inertial or Doppler systems reckoning (see ibid., p.6-8).

When the previously specified characteristics of movement of the first movable object 1 reset m-th intermediate transceiver station 5 is carried out in time

and

When the previously specified characteristics of the motion of the second movable object 2 reset the n-th intermediate transceiver station 5 is carried out in time

and

where τhmax- vertical lifting of the second movable object 2 from the common starting point Of the height hmax.

Formula (24) is due to the fact that the intervals in range Δ dndetermine the maximum possible distance between two intermediate and transceiver stations 5, discharged from the second movable object 2 in the next time.

Formula (25) is due to the fact that the range of db mindetermines the maximum distance from the second movable object 2 to the total initial point O corresponding to the time tb min.

In the General case, the first movable object 1 and the second movable object 2 can make movement difficult routes. In particular, they may first be removed from the common starting point Of, and then to approach him, then again be removed and closer, etc. With the first movable object 1 and the second movable object 2 may repeatedly pass through a common starting point and, therefore, repeatedly placed him at distances less than da minand db minrespectively. However, the reset intermediate transceiver stations 5 with the first movable object 1 is not carried out only until the time of the first removal of the first movable object 1 from a common initial point O, the distance da min. From this point in time with the first movable object 1 discharge intermediate transceiver stations 5 intervals range defined by the given ranges of validity transmitting station 3 and the intermediate transceiver stations 5, and the intermediate reset primop redusa stations 5 is carried out in the case, if the movement of the first movable object 1 along the route distance common starting point On will again become less than the value of da min.

For the second movable object 2 is similar: reset intermediate transceiver stations 5 from the second movable object 2 is not carried out only until the time of the first removal of the second movable object 2 from a common initial point O, the distance db min. From this point in time from the second movable object 2 discharge intermediate transceiver stations 5 intervals range defined by the given ranges of validity transmitting station 3 and the intermediate transceiver stations 5, and the intermediate reset transceiver stations 5 is carried out and in that case, if the motion of the second movable object 2 on the route distance common starting point On will again become less than the value of db min.

If the wind speed is negligible, the velocity Vaand Vbthe movement of the first movable object 1 and the second movable object 2 is also so small that they do not cause significant disturbance of air masses, the trajectory of the fall intermediate transceiver stations 5, you can take vertical. While the aerodynamic properties of structures intermediate primape edusa stations 5 should not have any special features, causing a significant deviation of the trajectories of falling from a vertical.

After falling on the surface of the intermediate transceiver station 5 remain motionless.

The factors k2and k3take into account the possible inaccuracy of the scatter intermediate transceiver stations 5, due to the influence of various factors.

Since the timeandthe beginning of movement of the first movable object 1 and the second movable object 2, as well as their velocity Vaand Vbin the General case are different, there are four characteristic cases:

When the movement of the first movable object 1 and the second movable object 2 routes, the length of which is equal respectivelyandall four conditions (26)-(26). In each moment of time is only one of the specified conditions. In addition, due to the irreversibility of time, if it is one of the conditions (26, b)-(26), the condition (26) will not occur; if it is, the condition (26, g), then none of the conditions (26)-(26) also will not come. Thus, from the presentation the frame should the method can be carried out only in one way.

In the first case (26, a) or with the first movable object 1 or the second movable object 2 reset intermediate transceiver stations 5 do not exercise. The implementation of the method in this case considered above.

Consider the implementation of the method in cases (26, b)-(26), which corresponds to the reset intermediate transceiver stations 5 with the first movable object 1 or/and the second movable object 2.

If, in accordance with condition (26), the reset intermediate transceiver stations 5 is carried out with the first movable object 1 and the second movable object 2, the method consists in the following.

From the first movable object 1 transmit radio signals. Take transmitted from the first mobile object 1 radio on the last (m=mmax) discharged from the first movable object 1 intermediate transceiver station 5 and pass them. Accept sent with the given (m=mmax) intermediate transceiver station 5 radio signals on the penultimate (m=mmax-1) discharged from the first movable object 1 intermediate transceiver station 5 and pass them. Similarly carry out reception and transmission of radio signals using other previously discarded (m=mmax-2, mmax-3,... ,1) with the first movable object 1 p is omegatech transceiver stations 5 in the direction of transmission of the radio signals from the reset intermediate transceiver stations 5 in the later moments of time t mto reset to an earlier point of time tμ where m>μ . Accept transferred from the first (m=1) discharged from the first movable object 1 intermediate transceiver station 5 radio signals to the first (n=1) dropped from second movable object 2 intermediate transceiver station 5 and pass them. Accept transferred from the first (n=1) dropped from second movable object 2 intermediate transceiver station 5 radio signals for the second (n=2) dropped from the second movable object 2 intermediate transceiver station 5 and pass them. Similarly carry out reception and transmission of radio signals using other discarded at a later time from the second movable object 2 intermediate transceiver stations 5 (n=3,4,... ,nmax) in the direction of transmission of the radio signals from the reset intermediate transceiver stations 5 in earlier times tnto reset at a later time tν where ν >n. Take the second movable object 2, the radio signal transmitted from the last (n=nmax) discharged from the second movable object 2 intermediate transceiver station 5.

If, in accordance with condition (26)reset intermediate transceiver stations 5 is carried out only with the first movable object 1, the transfer radiosignal the first movable object 1 by using the reset with the first movable object 1 intermediate transceiver stations 5 (m=1,2,... ,mmax) is similar to the above case (26 g), and receiving transmitted from the first (m=1) discharged from the first movable object 1 intermediate transceiver station 5 radio signals carry on the second movable object 2.

If, in accordance with condition (26, b), the reset intermediate transceiver stations 5 is carried out only from the second movable object 2, the transmission radio signal with the first (n=1) dropped from second movable object 2 intermediate transceiver station 5 using (n=2,3,... ,nmax) discharged from the second movable object 2 intermediate transceiver stations 5 is similar to the above case (26 g), and receiving transmitted from the first mobile object 1 carry out radio signals to the first (n=1) dropped from second movable object 2 intermediate transceiver station 5.

Each intermediate transceiver station 5 starts to operate at the time of reset and continues to function before and after contact with the underlying surface.

At lower intermediate transceiver stations 5 of their range and the range of radio broadcast stations 3 are reduced, but, in accordance with formulas (7)-(18), does not become less than the value of Rmin.

The mutual displacement of the first movable lens is the 1, the second movable object 2 and discharged from the intermediate transceiver stations 5 occurs Doppler effect, the negative impact on the communication quality can be resolved by rational choice of the frequency characteristics of signals and devices transmitting station 3, a receiving station 4 and the intermediate transceiver stations 5.

When implementing the method in rough terrain to determine discharge points intermediate transceiver stations 5, you must take into account the information about the height field terrain. For this purpose, the first movable object 1 and the second movable object 2 can be used in the review and comparative systems of navigation (see Aeronautical radionavigation: a Handbook. Edited Ass. - M.: Transport, 1990, p.8-9).

The underlying surface may be the surface of the water. In this case, when implementing the method, you must keep the intermediate transceiver stations 5 on the surface of the water after a fall. In addition, when specifying ranges of validity transmitting station 3 and the intermediate transceiver stations 5, consider the excitement of the water surface and possible flow.

The term “operating frequency” understand the value of carrier frequency oscillations, Central or any other characteristic is Chernoe the frequency band of radio signals. When this band of frequencies of the radio signals, corresponding to different operating frequencies do not overlap.

For an arbitrary routes of movement of the first movable object 1 and the second movable object 2 set the operating frequencies of the radio signals transmitted at the same time with the first movable object 1 and each of the intermediate transceiver stations 5 discharged from the first movable object 1 and the second movable object 2 must be different

When the radio transmission from the first mobile object 1 on the second movable object 2 given operating frequency, radio signals received by the m-th reset with the first movable object 1 intermediate transceiver station 5, except the last one (m=mmax) discharged from the first movable object 1 intermediate transceiver station 5 is specified operating frequency fm+1radio signals transmitted from the (m+1)-th intermediate transceiver station 5 discharged from the first mobile object 1 is closest to the time reset time tmthis (m-th) intermediate transceiver station 5 later time tm+1

Specified operating frequencyradio signals received at last the days (m=m max) discharged from the first movable object 1 intermediate transceiver station 5 is specified operating frequency faradio signals transmitted from the first mobile object 1

Specified operating frequencyradio signals received on the n-th reset from the second movable object 2 intermediate transceiver station 5, except for the first (n=1) dropped from second movable object 2 intermediate transceiver station 5 is specified operating frequency fn-1radio signals transmitted from the (n-1)-th intermediate transceiver station 5 discharged from the second movable object 2 at the time tnreset this (nth) intermediate transceiver station 5 earlier time tn-1

Specified operating frequencyradio signals received at the first (n=1) dropped from second movable object 2 intermediate transceiver station 5 is specified operating frequencyradio signals transmitted from the first (m=1) discharged from the first movable object 1 intermediate transceiver station 5, if the first movable object 1 reset at least one intermediate preempted the maintenance station 5, or, otherwise, the specified operating frequency faradio signals transmitted from the first mobile object 1

Specified operating frequencyradio signals received on the second movable object 2 is specified operating frequencyradio signals transmitted from the last (n=nmax) discharged from the second movable object 2 intermediate transceiver station 5, if the second movable object 2 is reset at least one intermediate transceiver station 5, or given operating frequencyradio signals transmitted from the first (m=1) discharged from the first movable object 1 intermediate transceiver station 5, if the intermediate transceiver station 5 reset only from the first mobile object 1, or given operating frequency faradio signals transmitted from the first mobile object 1, if no the first movable object 1 or the second movable object 2 is not reset any intermediate transceiver station 5 (the characteristic inherent in the prototype, and therefore it is included in the General part of the stated claims):

From the above it follows that the operating frequencies of the radio signals received by p is omegatech transceiver stations 5 and transmitted with them, can be fixed.

In this case, when the discharge from the first movable object 1 regular (m=mmax) intermediate transceiver station 5 desired operating frequency faradio signals transmitted from the first mobile object 1 must coincide with the given operating frequencyradio signals received on the given (m=mmax) intermediate transceiver station 5. Before discharge from the first movable object 1 first (m=1) intermediate transceiver station 5 desired operating frequency faradio signals transmitted from the first mobile object 1 must coincide with the given operating frequencyradio signals received at the first (n=1) intermediate transceiver station 5 discharged from the second movable object 2.

However, when the discharge from the second movable object 2 regular (n=nmax) intermediate transceiver station 5 desired operating frequencyradio signals received on the second movable object 2 must coincide with the given operating frequencyradio signals transmitted from a given (n=nmax) intermediate transceiver station 5. Before discharge from the second movable object 2 of the first (n=1) intermediate transceiver station 5 given what I'm working frequency radio signals received on the second movable object 2 must coincide with the given operating frequencyradio signals transmitted from the first (m=1) intermediate transceiver station 5 discharged from the first movable object 1.

In addition, for the implementation of the radio communication between the first mobile object 1 and the second mobile object 2 in the situation of (26), in which they have not dropped a single intermediate transceiver station 5, the specified operating frequency faradio signals transmitted from the first mobile object 1 must coincide with the given operating frequencyradio signals received on the second movable object 2.

Art circuitry. - M.: Mir, 1993, s-295), not shown in figure 2, 3.

The first block 9 is reset and the second block 13 reset are designed to perform reset intermediate transceiver stations 5 with a specified interval in range.

As the first conveyor 15 and the second conveyor 19 used belt conveyors with horizontal closed track (see, for example, the Conveyors. The Handbook. Under the General editorship Uairen. L.: engineering, 1984, p.4-9).

The first conveyor 15 is designed to move the intermediate transceiver stations 5, placed in the first bearing elements 17, in the direction of eromu hole 26. The second conveyor 19 is designed to move the intermediate transceiver stations 5, placed second bearing elements 21, in the direction of the second hole 28.

The first actuator 14 and the second actuator 18 are automated. Systems of automated control of electric drives provide a given angular velocity of the shaft of the motor in accordance with external control signals, which, depending on the type of motor and control system can be analog or digital (see, for example, Polytechnical dictionary. The editorial Board.: Awesomse (editor-in-chief) and other 3rd ed., Rev. and supplementary): P “Great Russian encyclopedia”, 1998, s). The design of the actuator is known (see, for example, the Conveyors. The Handbook. Under the General editorship Uairen. - L.: engineering, 1984, p.87-91).

The power of the signals generated by the first control unit 8 and the second control block 10, is sufficient to control the operation of the first actuator 14 and the second actuator 18.

The first transmitting antenna 33, the first receiving antenna 34, the second receiving antenna 44 and the second transmitting antenna 53 are non-directional.

Construction of the intermediate transceiver stations 5 will be developed with consideration of impact loads that occur when confronted with the underlying surface (see, for example, Webcamporn. Vibration and shock in radio. - M.: Soviet radio, 1971, s-216). In this regard, the second receiving antenna 44 and the second transmitting antenna 53 of the intermediate transceiver stations 5 can be placed inside the high impact of the radio waves buildings made for example, fluoroplastic.

Parachutes 23 serve to reduce the speed of falling intermediate transceiver stations 5 and, consequently, to reduce the shock loads that occur when they collide with the underlying surface.

The parachutes 23 second bearing elements 21 eliminates the tangling of slings 22 resetting the intermediate transceiver stations 5.

The physical and geometric characteristics of parachutes 23 (permeability, elasticity fabric dome, the shape and size of the dome, the presence and shape of the cutouts and other) is determined based on the weight of the intermediate transceiver stations 5 and the required dynamics of parachutes 23 (see, for example, Wasiljev, Vnesheco, Whatamango. Dynamics of parachute systems. - Kyiv, Odessa: “high school”. Head publishing house, 1985). Design and characteristics of parachutes 23 assume their automatic disclosure of resetting the intermediate transceiver stations 5.

The term “controlled generators the top” is a generally accepted (see, for example. Theoretical bases of radar. Edited Vaitulevich. - M.: Soviet radio, 1978, s). The oscillation frequency generated by the controlled oscillator is determined by the voltage acting on its control input. In this case, the controllable oscillator is controlled oscillator voltage. Generators driven by voltage, are known and described in the literature devices (see, for example, Horowitz P., hill. U. Art circuitry. In 3 volumes: T.1. TRANS. from English. - 4th ed. revised and enlarged extra - M.: Mir, 1993, s).
