Technical solutions with features distinguishing the claimed solution from the prototype are not known and do not follow explicitly from the prior art. This suggests that the claimed solution is new and has an inventive step.

The invention is illustrated by the drawing, which shows the structural system of information exchange of the top loader.

The top-binder information exchange system contains the following main channels of information exchange: two radio channels 1 and 2 of navigation equipment for consumers of space navigation systems (NAP KNS) 3, stationary mounted on the top binder, with navigation spacecraft (NSC) KNS GLONASS 4 and GPS 5, two radio channels exchange 6 and 7 of the portable military navigational-geodetic complex (VNGK) 8 with the NSA KNS GLONASS 4 and GPS 5, two radio channels 9 and 10 of the control and correction station (KKS) 11 with the NSA KNS GLONASS 4 and G PS 5, two automated radio channels for the exchange of 12 and 13 radio stations (PC) 14, permanently installed on the top loader, with consumers of navigation information (P) 15 obtained when the top loader performed tasks for the purpose, and corrective information for monitoring the quality of the GLONASS and GPS navigation fields, received from KKS 11, radio channel 16 between two wearable radio stations (LDCs) 17 when working with VNGK 8 or external equipment: busol (B) 18, theodolite (T) 19, range finder (D) 20, cable channel for internal exchange 21 between hardware wed Topopriver’s features: autonomous topographic reference and navigation equipment (AATN) 22, NAP KNS 3, height determination system (SOV) 23, Doppler speed sensor (DSD) 24, mechanical speed sensor (DSM) 25, KKS 11, visual and textual and graphic display channel information 26 based on a video monitor (VM) 27 SEVM 28, an exchange channel 29 from external information storage devices: a CD-ROM 30 drive, an information recording and transmission device (USPI) 31, a channel for manual input of information 32 based on a keyboard (K) 33 computer 28, the registration channel on paper text and graphic information 34 on the basis of a documenting device (UD) 35, a voice information exchange channel between crew members 36 on the basis of a loud-speaking transport device (TSU) 37, a channel for visual monitoring and reconnaissance of the surrounding area 38 on the basis of remote equipment: B 18, T 19, D twenty.

A topographic information exchange system ensures the functioning of information flows in solving the tasks of topographic and geodetic training of combat operations of missile forces and ground forces artillery using a topographic reader.

To ensure the required accuracy in determining navigation information, information is integrated in a computer 28 with sensors built on various physical principles: DSM 25, DSD 24, AATN 22, SOV 23 and NAP KNS 3. Information exchange is carried out through the cable channel of internal exchange 21, laid in the back of the truck - the van of the vehicle on which the top loader is located, in accordance with the developed exchange protocols.

NAP KNS 3 on channels 1 and 2 provides automatic search, reception and processing of radio signals emitted by the spacecraft:

1) SPS GLONASS 4 (based on the signals of the PT- or VT-code);

2) GPS 5 GPS (based on C / A code signals);

3) according to the combined grouping of NCA of these CNS.

After that, there is an automatic determination (calculation) of three (latitude, longitude and height) current coordinates of the topographic location, vector of ground speed, azimuth, directional angle and current time.

The combined use of GPS and GLONASS systems is more effective than autonomous work with one of them. Firstly, due to the actual increase in the total number of satellites, the coverage area of the navigation signal expands; secondly, because GPS and GLONASS operate in different frequency ranges, the joint receiver is more resistant to probable narrow-frequency jamming of the navigation signal; thirdly, it becomes possible to monitor the integrity of the group and exclude faulty satellites from the working constellation.

Similarly, the use of VNGK 8 is used, which works with radio channels 6 and 7 on the NKA KNS GLONASS 4 and GPS 5. Moreover, VNGK 8 provides the accumulation and primary storage of navigation information with the possibility of further post-processing.

The information exchange between the KKS 11 receiver and the NSS KNS GLONASS 4 and GPS 5 occurs respectively on the radio channels 9 and 10. Based on the results of the information exchange, KKS 11 provides the solution to the following main tasks:

- reception of signals of all located in the field of view of the spacecraft of the CNS GLONASS and GPS in the range L1 / L2;

- measurement of the pseudorange and carrier phase for all received signals of the GLONASS and GPS stations, the timing of measurements to the GLONASS CNS system scale, their registration at a given rate and real-time delivery to the consumer;

- Calculation and generation of corrective information for navigation signals of the GLAASS and GPS;

- continuous quality analysis of calculated and transmitted corrective information.

Integrated navigation data received from DSM 25, DSD 24, AATN 22, SOV 23 and NAP KNS 3 and processed in the computer 28, in an automated mode provided by one of the PC 14 short-wave range, channel 12 is transmitted P 15 - to the higher command or served units RV and A SV. In a similar mode, the correction information is transmitted from the KKS 11 through another PC 14 on channel 13.

All the channel-forming communication equipment of the top-binder is an integral part of the communication and data exchange subsystem of the basic set of the RViA ESU T3 control subsystem.

In addition, an additional radio channel 16 between two LDCs of the 17 meter range is implemented in the topper. This channel is used when working with VNGK 8 for communication between operators located at the reference and defined points. LDC 17 can be used for communication with a top loader when working with external equipment: B 18, T 19, D 20.

For a visual display of the operating modes of the topographic information system and navigation of the topographic data link, channel 26 is implemented on the basis of VM 27 of SEVM 28.

To enter software, cartographic material, an exchange channel 29 from external information storage devices was implemented: a CD-ROM 30 drive, an ultrasonic scanning device 31, which allows, in particular, to quickly provide cartographic formation of the work area.

To control the operating modes of the top-loader navigation system, to manually enter the source data when performing navigation tasks, to solve service problems, a channel for manual input of information 32 based on K 33 computer 28 is implemented.

For the printing production of the required number of topographic maps with topographic and geodetic information printed on them, the printing of measurement data performed by KKS 11, and the results of solving service problems, a recording channel on paper for textual and graphic information 34 based on UD 35 has been implemented.

To transmit voice information from the driver and commander to the top-loader box body to the operators and from the operators to the topo-loader’s cabin, a channel of voice information exchange between crew members 36 based on TSU 37 was implemented.

Also, a visual control and reconnaissance channel 38 was implemented in the toppropper on the basis of remote equipment: B 18, T 19, D 20, which allows:

a) at the observation post:

- determine the main direction;

- measure horizontal angles between the main direction and the goals;

- measure the elevation angles of targets;

- determine the magnetic azimuths (compasses) of directions to the target;

- mark the main gun of the battery;

- measure deviations and the height of the gaps;

- monitor the goals;

b) at the firing position:

- determine the angle of the gun’s firing plane;

- give the main gun a direction along a given compass;

- measure shelter angles;

- break the front of the battery.

Thus, in the present invention, the problem is solved to achieve a technical result, which consists in creating a topographic information exchange system with sufficient bandwidth of wired and radio channels connecting internal and external devices, and providing high accuracy in determining navigation parameters, a high degree of automation and speed information processing, the ability to access the required number of both internal and external users lei, expanding capabilities when using external equipment, the ability to use powerful automated communication systems.
