The invention relates to the field of satellite navigation and can be used to determine the position of mobile objects in space and their management.

Known methods of navigation objects, the signals of global navigation satellite systems, based on the reception of signals from navigation satellites (NCA) global navigation satellite systems, the measurement of the pseudorange between the NCA and the object and determining the position of the object by solving a system of equations based on the measured pseudorange and the calculated coordinates of the NCA. In order to increase positioning accuracy using reference points from which the object is passed corrective information to reduce the natural error of measurement of pseudorange (see EN 2185637, G 01 S 5/00 20.07.2002, EN 2213979, G 01 S 11/00, 10.01.2003, US 6662108, G 01 C 21/26, 09.12.2003, US 2003/0145328, G 01 S 5/00, 31.01.2003).

A disadvantage of the known methods is the dependence of the accuracy of positioning objects on the distance to the reference point. In addition, it does not solve the problem of control of mobile objects.

The technical result is an increase in positioning accuracy and the ability to manage mobile objects.

To achieve this result around each telecentre is created from the “m” control and correction stations (the COP), forming a local differential correction signals of the navigation satellites (NCA), which by radio transmitted to the telecentre, and then through the transmitter telecentre without disrupting the current broadcast is transmitted to a mobile object, which signals the NCA based on local differential corrections determines its own coordinates, transmitted over the air in the telecentre, where they are transmitted to the control point movement. From the point of traffic control signals traffic control together with the coordinates of the object are transferred to the closest to the mobile object control point satellite communication channels where signals are formed targeting mobile object, which by means of the transmitter telecentre address are transmitted to the mobile object.

The drawing shows a block diagram of a system that implements the method.

The system comprises a navigation space vehicles (NSV) (1), control and correction station (2), television (3), space communication device (4), control stations (5), the mobile object (6), the control point movement (7).

How precise positioning and monitoring of mobile objects is implemented as follows.

Using the positioning system of the mobile object, taking signals from the NCA (1) and local differential PDP is Cai, transmitted by the television signal, determines their coordinates.

Local differential corrections are called amendments, formed local differential systems. Local differential systems are the systems with a range of 200 km (see “global satellite navigation system GLONASS edited Vinaria, M., IPGR, 1998, p.18-27).

Local differential systems typically include one CCF (2).

Control and correction station (2) form a local differential correction signals with different NSV (1).

These amendments are passed to the local telecentre (3), which in this case means two-way radio equipment and antenna (tower). Without disturbing the current broadcasting, the amendments are passed from telecentre (3) on mobile objects (6), where they are taken into account when determining the location.

Determining the location of a mobile object (6) transmits information about their coordinates via radio to television center (3), where it enters the control point movement (7), which forms the strategic information management mobile object, indicating, for example, at what point they need to move. This information, together with the coordinates of the mobile object through space communications (through elimination of the STV space communications (4)) comes closest to the mobile object (6) dispatch the item (5), which forms of tactical management information, the mobile object (6) (binding to the terrain, roads, etc). This information is transmitted via the transmitter local telecentre (3) address of the mobile object (6).

The use of telecentres 3 (towers antennas) allows to cover a large area, for positioning and monitoring of mobile objects (6) without creating new systems, since the structure of the television without any significant modifications allows you to implement these steps. The use of space communication allows monitoring of mobile subscribers globally.

How precise positioning and monitoring of mobile objects, which consists in the fact that around each telecentre form a zone of “m” control and correction stations, where m is any integer that generates the signals of the navigation of spacecraft local differential corrections, which radio is transmitting at the telecentre and, through the transmitter telecentre, without disrupting the current broadcast, to the mobile object, which signals the navigation of spacecraft based on local differential corrections determines its own coordinates that are radio transmitted to the television station where they are transferred to the control point d is geniem, the signals control traffic generated at the point of motion control, together with the coordinates of the mobile object is passed to the closest to the mobile object control point satellite communication channels where signals are formed targeting mobile object, which by means of the transmitter corresponding telecentre address is passed to the mobile object.
