Abstract
A method of calculating two position fixes, using satellite positioning. The method comprises: using an RF front-end (), receiving satellite positioning signals; using an analogue-to-digital converter (), sampling the received signals to generate signal samples; using a processor (), processing a first set of the samples as they are generated, to calculate a first position fix; storing information associated with the calculation in a memory (); storing a second set of the samples, or ranging measurements derived from the second set of samples, in the memory () for later processing to calculate a second position fix; and later, processing the second set of samples to calculate the second position fix, wherein the calculation of the second position fix is assisted by the information associated with the calculation of the first position fix. Also disclosed are other related methods and apparatus.
