The present invention relates to measuring systems and can be used to monitor the position of moving trains. The invention is used to control the location of rolling stock. A known system for controlling the position of moving objects (for example, railway rolling stock application No. 62-44226 Japan), in which along the path of the mobile object is deployed line inductive radio, having N (where N>3) conductors with a repetition period P, arranged with a shift of P/N. For each conductor serves N-phase electric current with direct or reverse phase sequence. Two transport antenna of a moving object located at a certain distance from each other along the line of the radio, take her signals. The phase shift of the received signals to determine the position of the object. In the system line radio is divided into small intervals corresponding to the intervals at which divided the entire route of the object. On each interval of the repetition periods differ [1]. The disadvantage of the system is the low accuracy of the positioning of the rolling stock. A known system for controlling the position of the rolling stock (prototype RF patent №2139215. Control system the provisions of the railway rolling stock. Publ. 199, Bull. No. 28), containing n navigation satellites, control and correction station consisting of series-connected receiving antenna, GPS receiver, transmitter amendments, modulator, transmitter and transmitting antenna of the transmitter parameter connected with the second input of the transmitter amendments, rolling stock, consisting of series-connected first receiving antenna, GPS receiver and the offset parameter, the output of which is connected with the information input navigation receiver, connected in series to the second receiving antenna, a receiver and a demodulator, the output of which is connected to a second input of the offset parameter, serially connected corrector speed transmitter path and transmitter location, speed sensor, the output of which is connected to a second input of the transmitter location, a second input of the GPS receiver is connected to a second input of the corrector speed, the third output of the navigation receiver is connected to a second input of the transmitter path [2]. The disadvantage of this system is the increased complexity of its implementation, due to the need to install special equipment in a fixed location with known coordinates and transmit corrections for rolling stock, which can be accomplished only with the help of RA is iocane. The objective of the proposed technical solution is the elimination of technical deficiencies identified in the prototype. The basis of the invention is to create a system that allows high accuracy to determine the location of rolling stock without the use of the radio channel and the installation of special equipment in a fixed location with known coordinates. The problem is solved in that in a system for controlling the position of the rolling stock, containing n navigation satellites, rolling stock, consisting of series-connected receiving antenna, GPS receiver and the offset parameter, the output of which is connected to a second input of the navigation receiver, the first output of which is connected to the first input of the corrector speed, a second input connected to the speed sensor, the second output of the navigation receiver connected to the first input of the transmitter path, a second input connected to the corrector speed, the output of which is connected to the transmitter location, the input connected to the memory block according to the invention in rolling stock introduced the isolated sensor interface connected to the first input of the offset parameter, a second input connected to the memory unit, the third input of the offset parameter is connected to the output of Vice the amplifier location. The essential difference between the proposed technical solution is that the rolling stock introduced the isolated sensor interface connected to the first input of the offset parameter, a second input connected to the memory unit, the third input of the offset parameter is connected with the output of the transmitter location. The advantage is the lack of control and correction stations, the absence of a radio channel between the control and correction station and rolling stock, which greatly simplifies the system. Figure 1 shows the block diagram of the control system location of rolling stock. Figure 2 shows an example of installation on a railway locomotive antenna GPS receiver and sensor stand-alone interface. Figure 3 shows a variant of the block diagram of construction of the offset parameter and transmitter location. Figure 4 shows the graph-scheme of algorithm of the offset parameter. The system contains n navigation satellites 11-1nthe rolling stock 2, consisting of a series connected receiving antenna 3, a GPS receiver 4 and the offset speed 5, to the second input of which is connected to the speed sensor 6, to the first input of the transmitter path 7 is connected to the output of the corrector speed, to the second input of the transmitter path 7 are connected to the Yong second output of the navigation receiver 4, the output of the transmitter path 7 is connected to the input of the transmitter location 8, the second input of the GPS receiver 4 is connected in series connected sensor isolated junction 9 and the offset parameter 10, to the second input of which is connected to the memory unit 11, the third input of the offset parameter 10 is connected to the output of the transmitter location 8. The system works as follows. On rolling stock 2 antenna 3 are signals from navigation satellites 11-1nfor example, systems "NAVSTAR" and "GLO-NASS and processed in the navigation receiver 4. From the first output of the navigation receiver 4 signals that contain information about the time of reception of navigation signals, the measured ranges to the respective satellites 11-1n(R1, R2... Rncome to the second input of the offset parameter. On the measured distances of the navigation receiver calculates the coordinates of the rolling stock [3]. When coming from the sensor is isolated junction 9 of the pulse on the passage of the rolling stock 2 isolated junction offset parameter 10 analyzes the coordinates received from the transmitter location 8 and selects from memory the coordinates of the nearest stand-alone interface. In the memory unit 11 stores the reference coordinates insulated joints and point uncertain reception of the m signals from navigation satellites. In the absence of a signal from navigation satellites 11-1nfrom memory selects the coordinates of the point with poor reception. The coordinates of these points must be determined with an accuracy better than 1 meter, by any known method, for example in differential mode [3]. In the corrector option 10 is the calculation of the amendments to the ranges ΔR1that ΔR2that ΔRnreference coordinates [3]. Received the amendments go to the second input of the GPS receiver 4, which adjusted the distances to the respective satellites 11-1n(R1, R2... Rn) is the calculation of the adjusted coordinates of the rolling stock 2. Calculated in the offset parameter 10 amendments to the measured ranges is stored and used until a new pulse from the sensor stand-alone junction 9. Output speed sensor 6, which detects the speed V1locomotive according to the number of revolutions of the wheel pair, the signal at the first input of the corrector 5 speed. To the second input of the corrector 5 speed data concerning the speed of motion V2on the basis of measurement of radio navigation options in the navigation receiver 4. In the corrector 5 speed is determined by the measurement error of speed by the speed sensor 6, i.e ΔV=V1-V2the magnitude of which is Oh then used in the corrector 5 speed for more accurate speed V ccomposition in the absence of signals from navigation satellites 11-1nfor example, in tunnels, i.e., Vc=V1-ΔV. Output offset speed 5 speed information Vcarrives at the first input of the transmitter 7. To the second input of the calculator 7 receives information about the current time t from the GPS receiver 4, information on the time tcwhen disturbed signals from navigation satellites 11-1nfor example the entry of a train in the tunnel, as well as data about the coordinates of the rolling stock 2 for time tc. In the transmitter path 7 by the velocity of the rolling stock 2 (Vcfrom unit 5 and data on the current time t from block 4 passed is determined by the composition of the path from time tcaccording to the formula P=Vc·(t-tc). Information about the traversed path P and the coordinates of the rolling stock 2 for time tccomes from the output of the transmitter 7 to the first input of the transmitter location 8. To the second input of the transmitter location 8 receives data from the memory block 11. In the memory unit 11 stores information about the nature of the railroad tracks in the tunnel (the radius of curvature, the slope of the path length of the tunnel and so on). In the transmitter location 8 according to information from unit 7 determines the location of the rolling stock 2 in which onnela, the obtained data are derived from the transmitter location 8 indication to the operator of the locomotive.

The algorithm for calculating the location of the rolling stock 2 with high accuracy on the basis of information received from the correction parameter 10 and transferred to the navigation receiver 4 shown, for example, s.285-288 [3]. The calculation speed of the rolling stock 2 is shown in p.223, 235 [4]. The transmitter 7, the transmitter location 8, the offset parameter 10 can be implemented based on a standard microprocessor block diagram, for example, on ñ.38 [5]. Structural diagram of a variant of construction of blocks 7, 8, 10 are shown in figure 2,which shows for example, the connection blocks 8, 9, 11 to the block 10.
