Claim:
1. A method of extracting pseudorange information using a mobile cellular device, the method comprising: accessing a Global Navigation Satellite System (GNSS) chipset which is physically remote from the mobile cellular device, wherein said GNSS chipset provides raw GNSS observables based upon signals received from a circularly polarized GNSS antenna; wirelessly transmitting the raw GNSS observables from said GNSS chipset to said mobile cellular device; extracting the raw GNSS observables by a processor of said mobile cellular device; receiving via a wireless transmission, at the mobile cellular device, GNSS corrections from at least one correction source that is separate from the mobile cellular device and the GNSS chipset; and using, by said processor, the raw GNSS observables, in addition to the GNSS corrections, to determine a position of said circularly polarized GNSS antenna.
