First Claim
Patent Images
1. A method of extracting pseudorange information using a cellular device, the method comprising:
- accessing a Global Navigation Satellite System (GNSS) chipset embedded within the cellular device, wherein the GNSS chipset calculates pseudorange information for use by the GNSS chipset;
extracting the pseudorange information from the GNSS chipset for use elsewhere in the cellular device outside of the GNSS chipset, wherein the accessing and the extracting are performed by the cellular device that includes hardware;
obtaining carrier phase information from the GNSS chipset, wherein the carrier phase information is real carrier phase information and wherein the obtaining of the carrier phase information further comprises extracting carrier phase measurements from the GNSS chipset, and deriving the real carrier phase information, external to the GNSS chipset, based on the extracted carrier phase measurements; and
storing the carrier phase information in memory located in the cellular device and outside of the GNSS chipset.

Abstract
Pseudorange information is extracted by a cellular device from a Global Navigation Satellite System (GNSS) chipset of the cellular device. The cellular device accesses the GNSS chipset embedded within the cellular device where the GNSS chipset calculates pseudorange information for use by the GNSS chipset. The cellular device extracts the pseudorange information from the GNSS chipset for use elsewhere in the cellular device outside of the GNSS chipset.
