- Abstract
This paper studied the determination of autonomous orbits of HY2A and ZY3 missions using on-board GPS data. A simulative on-board processing of real-time orbtt determination was carried out using the space-borne GPS dual frequency pseudo-range and phase measurements with the auto-developed software SATODS. The test demonstrates that,based on pseudo-rang data,the position and velocity error (3D RMS) of orbit results are up to1. 3 m and 1. 2 mm/s respectively,but with phase data,they are reduced to 38cm and 0. 36 mm/s for HY2A mission,where the radial accuracy is about 10 cm,and decreased to 54 cm and 0. 54 mm/s for ZY3 mission. These contributions can be used for certain real-time service of continued low-earth orbiters (LEO) for earth observations.
