Abstract

A first process and a second process are executed concurrently by one or more hardware processors located in the cellular device and outside of a Global Navigation Satellite System (GNSS) chipset embedded in the cellular device. The first process determines a first set of one or more position fixes based on extracted raw pseudorange information. The second process determines carrier phase smoothed pseudoranges based on carrier phase information and determines a second set of one or more position fixes based on the carrier phase smoothed pseudoranges. One or more of the first set of position fixes are provided to a user while a predetermined amount of carrier phase information is not available for performing carrier phase smoothing. One or more of the second set of position fixes are provided to the user while a predetermined amount of carrier phase information is available for performing carrier phase smoothing.
