1. A method of estimating a satellite signal parameter in a satellite positioning system receiver, comprising:
- generating a plurality of correlation results between a satellite signal and a reference signal in response to a command from a processor;
estimating at least one satellite signal parameter from the plurality of correlation results using a co-processor integrated within the satellite positioning system receiver; and
providing the at least one satellite signal parameter to the processor.

Abstract
A method and apparatus for estimating a satellite signal parameter in a satellite positioning system receiver is described. In an example, a plurality of correlation results between a satellite signal and a reference signal is generated in response to a command from a processor. At least one satellite signal parameter is estimated from the plurality of correlation results using a co-processor integrated within the satellite positioning system receiver. The at least one satellite signal parameter is then provided to the processor.
