Abstract
A system for estimating carrier phases of radio signals in a satellite navigation system receiver for coordinate determination includes a complex of reference signals (CRS), wherein, in each jsatellite channel, a digital reference signal RefSig, represents an output phase and frequency-controlled oscillation of a corresponding numerically-controlled oscillator (NCO) for each jsatellite channel, the phase of the oscillation of the NCOtracking a carrier signal received from the jsatellite; and an adaptation complex (AC) that, in response to vibration or movement of the receiver, changes (expands or reduces) an effective bandpass of the CRS, producing control signals that determine phase and frequency changes in the corresponding NCOfor reducing dynamic distortions in coordinate measurements.
