FIELD: high-accuracy landing systems in poor visibility with the aid of several navigation receivers working by signals from GLONASS AND GSP systems.
SUBSTANCE: proposed system is provided with navigational satellites of GLONASS and GSP systems and receiving unit which is engageable with them and is located on flying vehicle; system is also provided with "n" ground phase navigation receivers (n>3) located near runway; they are used for forming magnitudes of pseudophases and pseudorange at one and the same moment of time by signal received from navigation satellites; these magnitudes are transmitted to reception center by means of transmitting unit for forming navigation frame and information frame transmitted to flying vehicle. Signals received from all navigation satellites within visibility range are processed together with signals from ground phase navigation receivers.
EFFECT: enhanced reliability of landing.
