FIELD: measurement equipment.
SUBSTANCE: group of inventions relates to trajectory measurements using a tracking station (TS) for flight of a space vehicle (SV). At information exchange with SV via a radio channel TS makes a measurement of distance to SV and speed of its change. The main and additional TS antennas receive a signal response from SV and transmit it to an interferometric measurement unit (IMU) having a phase bearing finder. Azimuth angles and places of SV and speeds of their change are determined in IMU. In order to disclose ambiguity of angular measurements, they are additionally made on the frequency emitted from SV board and equal to 1/4 of the main one. This allows using no antennas on TS, which create shortened bases. All the six measured parameters (distance, angles and speeds of their change) are transmitted to a ballistic centre, where trajectory and forecast of SV movement is determined according to them.
EFFECT: simplifying a tracking network of SV flight at performance of trajectory measurements.
