SGS85-WGS84 Transformation: Interim Results

Abstract : GPS and GLONASS employ different geocentric Cartesian coordinate frames to express the positions of their satellites and, therefore, of their users. GPS uses WGS84; GLONASS, SGS85. Interest in the civil aviation community in using signals from both systems requires that a transformation between the two coordinate frames be determined. We present an estimate of the SGS85-WGS84 transformation. GPS, Satellite navigation, GLONASS, Geocentric coordinate frames, WGS84, Similarity transformation. SGS85,
