ABSTRACT:
A method for using a value of range rate observed by a receiver, such as a GPS receiver, at a particular location, along with other satellite information, to determine the coordinates of points on the surface of the earth from which this value of range rate would be observed. These coordinates are given in an earth-centered, earth-fixed (ECEF) coordinate system, and they form a locus of points of equal range rate. The coordinates of these points provide estimates of the location of the GPS receiver.
