THE EFFICIENCY ANALYSIS OF THE POSITION, VELOCITY AND HYBRID CORRECTION IN THE INTEGRATED NAVIGATING SYSTEM AT INCOMPLETE SATELLITE CONSTELLATION

摘要

As a part of integrated system software the velocity, positional and hybrid correction circuits on measuring of pseudo-range and a pseudo-velocity at small (1-3) number of visible GLONASS satellites are considered. The measurement errors caused by time scale drift of the receiver are taken into account. Selection of the best correction circuit is justified on modeling with usage of the real flight telemetry. Stability requirements of the receiver oscillator are determined.
