In order to achieve high precision GNSS (Global Navigation Satellite Systems) positioning, accurate modeling of the disturbance forces acting on GNSS satellites, including Japanese QZS-1 (Quasi-Zenith Satellite-1), is essential to minimize the contribution of the satellite orbit and clock errors. This study focuses on the development of analytical non-conservative force models for QZS-1 precise orbit determination, especially solar radiation pressure (SRP) and thermal re-radiation pressure (TRP) forces. In order to evaluate the performance of the proposed analytical model, the acceleration profile obtained by the traditional empirical SRP model was used as a reference. Results showed that TRP was major error sources and should be modeled separately from SRP. A ray tracing study also showed that the shadow effect of the large L-band antenna cover of the QZS-1 was not negligible and should be treated properly in the SRP calculation.
