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 and stored in a memory. 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. As the coprocessor estimates the parameter, new correlation results are added to the memory. The at least one satellite signal parameter is then provided to the processor.
