Abstract
A Global Navigation Satellite System (GNSS) chipset embedded within the cellular device is accessed. The GNSS chipset calculates raw observables that include raw pseudoranges and carrier phase information. The raw observables are extracted from the GNSS chipset for processing elsewhere in the cellular device outside of the GNSS chipset. Smoothed pseudoranges are provided by smoothing the raw pseudoranges based on the carrier phase information. The accessing, the extracting and the providing are performed by one or more hardware processors located in the cellular device and outside of the GNSS chipset.
