METHOD OF RECEIVING AND TRANSMITTING DIFFERENTIAL CORRECTIONS BY THE TOPOGRAPHIC SURVEY VEHICLE Russian patent published in 2018 - IPC G01C21/00 

FIELD: navigation; geolocation.

SUBSTANCE: invention relates to the field of navigation and geolocation, in particular to methods of satellite navigation and quality control of navigational fields of GLONASS and GPS space navigation systems, generating correcting information and analysis of its quality. To this end, the method of receiving and transmitting differential corrections by the topographic survey vehicle involves monitoring the operability, reception by the equipment of signals of satellite navigation systems GLONASS and GPS, reception and formation of the corrective information, continuous analysis of the quality of the calculated and transmitted correction information, the issuance of corrective information to the device for the transmission of differential corrections. Transmission and reception of differential corrections by the topographic survey vehicle is as follows: topographic survey vehicle is exposed on a point with known coordinates X, Y and height H, the software and hardware complex and the device for receiving and processing information of the basic control-correcting station are launched, radio station is switched on and tuned to the required frequency, the basic control-correcting station is tuned, for which a menu item "Initialization" is selected successively on the elements of the reference station and the integral control station, in the "Coordinates" tab in the "General and GPS coordinates" work field coordinates of the current location are entered and the "Recalculate for GLONASS" button is pressed, and in the "Used coordinate conversion parameters" field the "Fill" button is pressed, after loading the onboard computer of the hardware-software complex in the menu, the "ADF Setting" mode is selected, where the address fields of the data transmission equipment, addresses and signatures must be filled in, the "Navigation" window enters coordinates and altitude of the survey vehicle location, then it is necessary to go to the "Communication" window and control information from the base control-correcting station – the number of corrections from the satellite navigation systems GLONASS and GPS, and the issuance of amendments to consumers occurs automatically at their request, for the consumer it is necessary to enter the request address XXXXXX, where the last two digits in the query address field correspond to the ordinal number of the survey vehicle, from which differential corrections are transmitted, click the "Request" button, check in the Status window that the satellite navigation equipment has entered the correction mode.

EFFECT: technical result obtained in the implementation of the invention consists in the formation of a method for receiving and transmitting differential corrections by the topographic survey vehicle, providing the implementation of the algorithm for receiving and transmitting differential corrections to all possible consumers located in a single information network with a topographic survey vehicle, at their request through a single closed communication channel, which allows to increase the accuracy of the space navigation tools used by all users of signals of the GLONASS and GPS space navigation system in the positional area.
