Abstract
The effects of shock and vibration on a navigation receiver processing satellite signals received from global navigation satellites are reduced by controlling the frequency and the phase of the individual numerically controlled oscillator in each individual satellite channel. The frequency is controlled by an individual frequency control signal based on individual correlation signals generated in an individual satellite channel. The phase is controlled by a common phase control signal or a combination of a common phase control signal and an individual phase control signal. The common phase control signal is based on all the correlation signals generated in all the satellite channels processed by a separate common broadband quartz loop (SCBQL). An individual phase control signal is based on the individual correlation signals generated in an individual satellite channel.
