FIELD: space-system engineering.
SUBSTANCE: system can be used on the earth satellite vehicle in orbit except geostationary centers which are stabilised by rotation along the vertical axis, and the ground reception centers. The system contains an emergency object transmitter, spacecraft equipment and ground reception center equipment. Spacecraft equipment includes a horizon sensor, receiving antenna, comparison device, receiver, Doppler frequency meter, blocking-generator, two gating circuits, two valves, pulse generator, pulse counter, plug board chart, and magnetic storage device, transmitter, transferring antenna, modulation code generator, high-frequency generator and power amplifier. The ground reception center equipment includes reception antenna, high-frequency amplifier, two mixers, calibration frequency block, phase doublet, three narrowband filter, scale-of-two phase circuit, phase detector, Doppler frequency meter, computing unit and registration block.
EFFECT: it enlarges functional possibilities of the system.
