FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering, specifically to global navigation satellite systems (GNSS) consumer navigation equipment, which provides determination of coordinates, parameters of movement and current time of consumer on received navigation radio signals transmitted by navigation spacecrafts (NSC) from composition of orbital group of GNSS, in conditions of simultaneous reception of false navigation radio signals transmitted by special generation means and simulating true GNSS navigation radio signals. Technical result is achieved by using a navigation computer in a known device, the components of which are: a signal processor consisting of a module for assigning identification signs of signals to processing channels, M signal processing channels, an interface module; navigation processor, consisting of a module for determining and storing non-operational information on the state of the orbital GNSS constellations, a module for determining and storing operational information on the state of the NSC, a module for solving the task of navigation definitions, module for determining identification features and predicted energy of navigation signals of the NSC, a module for ranking identification characteristics of navigation signals of the NSC, an interface module, wherein m-th signal processing channel, where m=1, …, M, comprises a signal selection module based on an identification feature; module for estimating radio navigation parameters and signal energy, a module for identifying the presence and status of a signal, a module for controlling a procedure for searching for the next signal of a given identification feature in an unexplored space of allowable delay time values, a module for controlling a procedure for searching for the next signal of a given identification feature in an unexplored space of allowable values of Doppler frequency.
EFFECT: receiver of equipment of global navigation satellite systems signals, providing detection and blocking of false navigation signals, allows to solve the problem of navigation definitions with the highest situationally achievable reliability using a minimum number of processing channels, which is determined only by technical and economic criteria and does not depend on the number of received false navigation radio signals transmitted by sources of simulating radio interference.
