Abstract:
1. A method for calculating coordinates of a rover receiver, the method comprising the steps of: receiving, at the rover receiver, base data corresponding to a base, wherein the base data comprises: receiving a plurality of satellite orbit parameters at the rover receiver, each specific satellite orbit parameter in the plurality of satellite orbit parameters corresponding to a specific navigation satellite selected from the plurality of navigation satellites; calculating for each specific navigation satellite and for each specific base epoch a specific computed component; calculating for each specific base epoch a specific common component; calculating for each specific navigation satellite and for each specific base epoch a specific information component; calculating for each specific information component and for each specific base epoch a specific extrapolation function; calculating for each specific information component a specific extrapolated information component extrapolated to a rover epoch referenced to a clock in the rover receiver, wherein the specific extrapolated information component is calculated from: calculating for each specific navigation satellite a specific updated computed component at the rover epoch; calculating for each specific navigation satellite the sum of the extrapolated specific information component at the rover epoch, the updated computed component at the rover epoch, and the common component; and calculating the coordinates of the rover receiver based at least in part on the sum, calculated for each specific navigation satellite, of the extrapolated specific information component at the rover epoch, the updated computed component at the rover epoch, and the common component.
