FIELD: physics, measurement.
SUBSTANCE: invention is related to satellite navigation and may be used to build orbit-based functional addition to global navigation satellite system (GLONASS). Substance of method consists in the fact that on board of low-orbit spacecraft navigation equipment of user is installed, which is used to receive navigation messages, as well as additional equipment used to receive signals of on-air television of ground stationary television radio stations, bearing frequencies of two or more television channels are separated, on the basis of which Doppler shift of bearing frequencies is detected, orbit parametres are detected, calculating ephemerids of spacecraft, and navigation messages are formed in accordance with specified structure of navigation message, then radio navigation signals are broadcasted in direction of navigation information consumer location.
EFFECT: higher reliability of navigation detections of navigation information consumers performed with the help of GLONASS, due to increase of orbit-based navigation message sources number.
