ABSTRACT:
The present invention is directed to the determination of a relative position between moving platforms, using satellite-based navigation techniques and equipment installed on said platforms. It combines the concepts of observation-space and navigation-space differential systems, and operates a DGNSS base station in a time-varying mode, in order to rely on the built-in differential positioning and navigation capabilities of particular GNSS receivers while minimizing datalink loading and computational load in auxiliary processors. The invention achieves accurate relative positioning and navigation with respect to a moving base station, using DGNSS equipment that assumes it is stationary when operated in a reference station mode.
