Abstract : Doppler observations of artificial satellites made by mobile receivers have been used to determine the positions of navigation beacons and other isolated sites since 1963. Over this period, improvements in the accuracy of the satellite net of 15 to 20 base stations have yielded an improvement in the computed positions of the isolated sites from 100m to an estimated 1m. This report compares positions of the base stations computed from observations made over the past twelve years using recent geodetic parameters and methods to determine if systematic variations exist in computed positions.
