FIELD: code division radio communication systems.
SUBSTANCE: to control the flight of a low-orbit spacecraft, navigation satellites of the GLONASS system are used as relay satellites. Command-program information is recorded with code division when organizing a backup control channel in the backup bits of navigation frames. Navigation frames are received on a low-orbit spacecraft using the consumer's onboard navigation equipment.
EFFECT: increased stability and efficiency of control of a low-orbit spacecraft, simplification of algorithms for establishing and maintaining communication between a navigation satellite-relay and a spacecraft.
