Abstract
A satellite signal receiver is described. A front end receives a satellite signal. A sampling circuit digitizes the satellite signal, where the digitized signal has either a first sample spacing or a second sample spacing. A mode selection process selects either the first sample spacing or the second sample spacing. A processor performs at least a subset of a convolution between a pseudorandom reference code and the digitized signal.
