ABSTRACT:
A method for determining J location fix coordinates, such as (x,y,z,b) for J=2-4, for a selected location, such as a mobile station location, with increased accuracy, for a satellite-based or ground-based location determination (LD) system such as GPS, GLONASS or LORAN. Pseudorange corrections for the pseudorange values measured at the reference station approximately at an observation time t' are used to correct the pseudorange values measured at the selected location. Location fix coordinates are computed from the pseudorange values at the selected location or at the reference station, using an exact, invertible transformation T(t') between the J location fix coordinates and J pseudorange values. Information including the location fix coordinates is transmitted from one station to another with a reduced or minimal number of information bytes and with small dynamic ranges. Locations fix coordinates, as corrected using the pseudorange corrections, for the selected location are computed at the selected location, at the reference station or at a supplemental data processor, using the transformation T(t') and/or its inverse.
