Patent ID: 7719576

Claim:
A digital camera, comprising: an imaging unit for generating digital photographs; a front end for receiving satellite positioning system signals from one or more satellites and digitizing said satellite positioning system signals from the one or more satellites; and a memory for storing said digitized satellite positioning system signals from the one or more satellites with each digital photograph generated by said imaging unit, wherein said digitized satellite positioning system signals stored in said memory with each digital photograph comprises in-phase samples and quadrature samples; a data port configured to communicate with said memory; and a computer, coupled to said data port, for retrieving at least one digital photograph and corresponding said digitized satellite positioning system signals from said memory and for processing said digitized satellite positioning signals retrieved to produce location data, wherein said computer is configured to correlate the digitized satellite positioning system signals retrieved from said memory with pseudorandom reference codes to produce pseudorange data; and wherein the digitized satellite positioning system signals do not include location.
