METHOD FOR REMOTE MONITORING OF POSITIONING OF THE VEHICLES Russian patent published in 2019 - IPC G01S11/02 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the methods for measuring distances using radio waves and can be used to remotely monitor the location of vehicles. This result is achieved due to the fact that satellite navigation messages from N (N ≥ 4) navigation satellites are transmitted simultaneously to the first base station receiver, at the output of which the code measurements of the pseudo range of the base station from each satellite, and the receiver of the vehicle, at the output of which the code measurements of the pseudo range of the vehicle from each satellite are formed, which are transmitted from the receiver of the vehicle to the transmitter of the vehicle, at the output of which a message is generated, which includes the code measurements of the vehicle pseudo ranges, the vehicle identification code and the transmission time stamp, which is transmitted over the radio channel and is received at the base station by the second receiver, from the output of which the adopted vehicle identification code and code measurements of vehicle pseudo ranges, as well as code measurements of the vehicle pseudo range to the base station, which are generated in it, together with the output signals of the first base station receiver, are sent to the transmitter of the base station, where for each satellite the sum of the code measurements of the pseudo ranges of the vehicle and of the vehicle to the base station is formed, from which the code measurements of the pseudo range of the base station are subtracted and the residual equation between the obtained difference and its analytic expression in the geocentric coordinate system is formed, then, from the solution of the system of residual equations for four satellites selected from the calculation of the geometric factor of the base station, the current measurement interference and the current vehicle coordinates in the geocentric coordinate system are determined, which, together with the vehicle identification code, are sent to the transmitter of the base station, from the output of which together with the time stamp they are sent to the subscriber.

EFFECT: technical result achieved is an increase in the accuracy of determining the current coordinates (positioning) of vehicles and the possibility of implementing remote monitoring of their positioning when there is no navigation calculator on board the vehicle.
