  • HY2B, launched on 24 October 2018, is the first satellite of Chinese marine dynamic environment monitoring mission. It is mainly used to detect various marine dynamic environmental parameters such as sea surface height, sea surface wind field, and gravity field. Precise orbit tracking and determination is v ery key for the mission. The reduced-dynamic precise orbit determination for HY2B is carried out utilizing the spaceborne GPS observation in January 2021 and the orbit accuracy is evaluated by means of four methods. The results show that: (1) The average v alue of the carrier phase fitting residual is about 7.2mm, and the three-dimensional position difference between adjacent arcs of 28-hour orbit determination overlapping for 4h is less than 1.5cm; (2) Compared with the Precision Orbit Ephemerides (POE) issued by French CNES, the RMS average values of the difference in direction R, T, N and 3D are 1.5cm, 2.0cm, 1.5cm and 3cm respectively; (3)The SLR validation statistics RMS is about 2cm. (4) By applying PCV model constructed by residual method, the 3D RMS difference with CNES POE product is reduced from 3cm to 2.5cm. In conclusion, high -precision HY2B satellite orbit products can be obtained basing on space-borne GPS observation of the HY2B satellite.
