Considering the precision of the star table and the sensitive apparatus and the calibrated large field of view star sensors,the correction of starlight direction and nonspherical earth,the precision of the orbit determination is from 100m to 150m .

• 考虑到星表、敏感仪器和仪器标定精度,星光大气折射改正以及地球非球形几何改正,其定轨精度估计可达100m-150m。
