Features of creation of navigational system are analysed at low-level flight of flight vehicles with use of satellite radio navigating systems GLONASS/GPS and pseudosatellites, including, for increase of reliability of landing. Feature of considered system is that onboard the flight vehicle the repeater of signals of pseudosatellites is established. The onboard repeater receives signals from pseudosatellites and relays them in the aerial of the onboard receiver of satellite signals via the transmitting aerial. For increase of range of action of system on entrance of the power limiter the automatic power control unit, control which can be in addition actuated is carried out on the basis of calculation of distances from the flight vehicle to each pseudosatellite and transformation of this distance to level of output signal.
