Abstract
A method of extracting pseudorange information using a cellular device. A Global Navigation Satellite System (GNSS) chipset which is physically remote from a cellular device is accessed which provides raw GNSS observables information based upon signals received from a circularly polarized GNSS antenna. The raw GNSS observables information is wirelessly transmitted from the GNSS chipset to the cellular device. The raw GNSS observables information is extracted by a processor of the cellular device. The raw GNSS observables information, in addition to GNSS corrections from at least one correction source, is used by the processor to determine a position of the circularly polarized GNSS antenna.
