Abstract
A Global Navigation Satellite System (GNSS) chipset embedded within the cellular device is accessed. The GNSS chipset calculates raw pseudoranges. The raw pseudoranges are extracted from the GNSS chipset for processing elsewhere in the cellular device outside of the GNSS chipset. A position fix is determined based on the raw pseudoranges. Locally measured cellular device movement information is obtained from at least one sensor that is in a known physical relationship with the cellular device. The locally measured cellular device movement information is applied to the position fix.
