摘要

System for estimating carrier phases, including a receiver that receives radio signals from satellites; the radio signals are converted into digital signals; a plurality of channels, each including a correlator receives digital signals and outputs (I, Q) components for one satellite; a reset accumulator that receives (I, Q) components, accumulates them over multiple cycles of a pseudorandom code and outputs accumulated (Is, Qs); a discriminator that generates a tracking error signal; a CCLF (common controlled loop filter) receives the tracking error signal and outputs a frequency control signal and a phase control signal; NCO receives the frequency and phase control signals, and outputs a reference signal. CCLF also receives correction signals based on the radio signals due to shock, vibration or acceleration. NCO control signals depend on the correction signals due to a change in an effective bandwidth of the CCLF to reduce coordinate measurement dynamic distortions.
