Precise Orbit Determination for the BDS IGSO Satellites Under the Yaw-steering Mode

doi:10.11947/j.AGCS.2018.20180286

Abstract

Abstract: Considering the energy supply and security factors, both the orbit-normal mode and the yaw-steering mode are adopted in the BDS IGSO attitude control system. The irradiation instances for the satellite body and solar panel are different for the two attitude control mode, with different dynamic models. If using the ordinary dynamic models in the precise orbit determination (POD), the POD accuracy declines seriously during the yaw-steering period. Therefore the average availability falls 2% in the BDS key service area, and 4% in the BDS total service area, the service performance faces serious challenges. A new POD strategy is brought forward with the restriction of time offsets in this paper for the BDS IGSO satellites during the yaw-steering period. The time offsets application strategy, systematic error controlling strategy, and dynamic models errors compensation strategy are designed in this paper in order to solve the BDS IGSO POD accuracy falling problem. The IGSO satellites ephemeris is consecutive for the transformations between the orbit-normal mode and the yaw-steering mode. The BDS navigation service is consecutive, with the continuous and steady space signal accuracy for the IGSO satellites. POD experiments were carried out during the BDS IGSO yaw-steering period. Results showed that the user equivalent ranging error (UERE) is improved from 2.95 m to 1.22 m for the BDS C06 satellite, and from 6.29 m to 1.54 m for the BDS C09 satellite. The ratio of UERE less than 2.5 m is improved from 59.87% to 94.85% for the C06 satellite, and from 35.04% to 88.49% for the C09 satellite. And the ratio of UERE less than 5 m is improved from 92.10% to 99.98%for the C06 satellite, and from 71.67% to 99.43% for the C09 satellite.
