Abstract
A navigation receiver comprises a digital sampler that precedes digital signal processing which can operate at a high rate and a low rate. If the high rate is selected for noise reduction by non-coherent averaging, the samples are averaged over time and transformed to the low rate. The digital signal processor is fed only low-rate samples in either case.
