FIELD: physics.
SUBSTANCE: invention can be used for rapid monitoring of continuity of the navigation field of the global navigation satellite system (GNSS). Continuity if monitored on a low-orbiting spacecraft fitted with consumer navigation apparatus. During orbital flight, navigation messages of visible GNSS spacecraft are continuously received; navigational sighting is carried out; some of the received navigation messages are used and several sets of consumer coordinates are obtained. By processing redundant navigation information, the quality of navigation signals of all visible GNSS spacecraft are analysed. Upon detection of malfunction of a certain GNSS spacecraft, a fault feature is rapidly generated and transmitted, which is received in on-board control systems of the GNSS spacecraft and the fault feature is entered into the system log.
EFFECT: broader functional capabilities.
