Influence of Solar Radiation Pressure Model on GPS Precise Point Positioning
Abstract Using the 2019 doy110-139 observation data from 120 tracking stations around the world, we carry out precise GPS orbit determination. Then, we carry out PPP experiments using 7 stations not involved in orbit determination with three solar radiation pressure models: ECOM1, ECOM1+BW, ECOM1+ABW. The results show that the orbit accuracy obtained by the ECOM1+ABW combination model is highest, with three-dimensional orbit accuracy in no-earth eclipse seasons better than 4 cm. For static PPP, the accuracy of horizontal direction is better than 0.8 cm and the accuracy of vertical direction is better than 1.2 cm after convergence. For kinematic PPP, the convergence time is about 30 min. After convergence, the accuracy of horizontal direction is better than 1.4 cm and the accuracy of vertical direction is better than 2.0 cm.
