Exploiting the SIRGAS Colocations for Determining Elevation Dependent Phase Center Variations of Geodetic GPS Antennas
During the SIRGAS 95 GPS campaign several sites were continuously occupied during ten days by two different receiver systems. From the data acquired at all those colocation sites providing sufficiently accurate ground truth, either from terrestrial geodetic observations or from SIRGAS independent GPS measurements, the elevation dependent phase center differences between the involved antennas have been determined. The modelling approach and the achieved results are presented.
