FIELD: astronautics.
SUBSTANCE: method for performing trajectory measurements and determining the coordinates of a spacecraft (SC). The method for determining the coordinates of the main spacecraft x1, y1, z1 includes measuring, through correlation processing of radio signals in the transmitting and receiving radio station (TRRS), the time delay value ΔtK between the emitted and the received test radio signal of the TRRS after its retransmission by the main spacecraft, time delay valuesΔtH between the emitted and the received test radio signal of the emitting benchmark station (EBS) after its retransmission by the main spacecraft, and, for each earth station, the time delay valuesΔtn between the received radio signals after their retransmission by the main and the adjacent spacecraft, respectively. The coordinates of the main spacecraft x1, y1, z1 are calculated based on the specified time delays of the system radio signals.
EFFECT: improved accuracy of determining the spacecraft coordinates.
