Objective：Haiyang 2D satellite (HY-2D) is the fourth Marine dynamic environment satellite in China, which belongs to the Marine remote sensing satellite series in China, with high-precision orbit measurement, orbit determination capabilities and all-weather, all-day, global detection capabilities. The main mission of the satellite is to monitor and investigate the Marine environment, obtain a variety of Marine dynamic environmental parameters, including sea surface wind field, wave height and sea surface height, directly provide measured data for the early warning and prediction of catastrophic sea conditions, and provide support services for Marine disaster prevention and reduction, Marine rights and interests protection, Marine resources development, Marine environmental protection, Marine scientific research and national defense construction. After the launch of HY-2D satellite, HY-2B satellite and HY-2C satellite realize the three-star network observation. Accurate orbit of HY-2D is a prerequisite for mission accomplishment. It was equipped with the DORIS receiver for POD (precise orbit determination). The attitude of the satellite alternates between fixed mode and nominal yaw-steering mode. Method：In order to study the accuracy of orbit determination of HY-2D using DORIS, we build a satellite attitude model, and DORIS phase measurement data from June 5 to June 13, 2021, is selected, and the Epoch-Difference method and dynamic orbit determination method is adopted for precise orbit determination. Result：The orbital accuracy was then evaluated by post-fit residuals, overlapping, comparing with CNES and SLR. The differences between the two orbit determination results using attitude model and attitude data were discussed. The results show that:(1) Mean of the Post-fit residuals is 0.355mm/s, mean of 3D RMS is within 2cm. (2) Compare with the precise orbit by CNES, the RMS when using attitude data in the R, T and N directions are 1.02cm, 2.92cm and 3.11cm, respectively, and the RMS when using attitude model in the R, T and N directions are 0.97cm, 2.77cm and 3.15cm, respectively. The similarity between the two results indicates that the constructed satellite attitude model is in good agreement with the measured attitude data. (3) The mean RMS of SLR residuals for CNES orbit and our orbit are 2.38cm and 2.24cm respectively, indicating that the two orbits have similar accuracy. Conclusion：Our research shows that the on-board DORIS receiver have good and stable performance, by using the received data, we can provide a centimeter-level HY-2D satellite orbit, which can ensure the stable operation of satellite altimetry.
