RADIOTECHNICAL COORDINATE SYSTEM Russian patent published in 2020 - IPC G01S5/10 H04B7/02 H04W64/00 

FIELD: physics.

SUBSTANCE: invention relates to radio engineering and can be used to determine coordinates of a stationary or mobile radiotechnical object (RO). Radiotechnical system comprises a ground-based point-to-point transmitting system (GPTS) with at least four ordered numbered points. Each point comprises a transmitting antenna device (AD) connected to a device transmitting r/s (RD) configured to generate and transmit a r/s with given individual characteristics. Coordinates of phase centers (PC) of antennas of transmitting AD units are known at RO. Also, the GPTS includes a control ground-based radio engineering station (CS), having a receiving AD functionally connected to the receiving RD. At that, the CS contains either a receiving antenna module (RAM) connected to the receiving AD, which is configured to fix the position of the antenna PC of the receiving AD, and with the possibility of moving the CS antenna such that the moving antenna of the PC of mobile antenna (MA) moves along the predetermined circular path at a given angular velocity, or the CS includes a stationary receiving antenna connected to the receiving AD, and said RAM. Also, the CS includes a measurement-information subsystem (MIS) configured to measure, at a fixed position of the PC of MA, a frequency-deviation spectrum (FDS) of the received r/s from a given spectrum position for each point, and when moving PC of antenna - measuring projections of its speed, corresponding to their accelerations and derivatives of these accelerations in time on the lines connecting the PC of MA with the APC points, and the possibility of determining from these projections and said angular velocity of time varying in time, passage of r/s from the PC of MA to the APC points and time shifts for each point. Each point is equipped with an information system (IS) configured to use the FDS information received from the MIS for frequency adjustment for each point, and information on time shifts - for correcting the time delay of sending r/s of each point and providing general synchronization transmitted by all points r/s. RO has a functionally connected receiving AD, a receiving RD and a subsystem configured to determine relative distances from the APC RO to the APC of the points and determine the coordinates of the APC RO from the relative distances and coordinates of the APC points.

EFFECT: technical result is possibility of time synchronization for transmitting and receiving radio signals (r/s) of objects.
