摘要：

With the widespread application of high orbit satellites, the demand for their orbital accuracy is becoming increasing-ly high. Based on the spaceborne GNSS (global navigation satellite System) data, we simulate an inclined geosynchronous SAR satellite, and analyze the orbit determination accuracy. The results show that the high sensitivity onboard receiver can obtain the signal of about 20 satellites which include GPS and BDS, with PDOP (position dilution of precision) values ranging from 1 to 2. By using the pseudo range/carrier phase measurement values of spaceborne GNSS data, the orbit determination accuracy of inclined geosynchronous SAR satellites can be better than 1 m, and the fluctuation of high-order Legendre error is less than 10 mm. The perturbation of solar radiation pressure has a significant impact on the orbit, the model error of the 10 8 m • s order can reduce the orbit determination accuracy by one order of magnitude. © 2025 SinoMaps Press.
