中文摘要：

基于国际激光联测网观测资料,研究了不同定轨弧段条件下的COMPASS-M1卫星轨道的确定、预报及其质量评定。研究结果表明,定轨弧段取19d时,该卫星的径向、三维位置精度平均为0.207m、2.28m;预报1d时,径向、三维位置精度平均为0.25m、2.75m。

英文摘要：

COMPASS M1 satellite orbits with different arc lengths are determined based on SLR-only data collected from the ILRS tracking network. Orbit overlaps and range residuals are derived to assess the orbit quality. SLR-based orbits of 19 days arc length are determined with an accuracy of about 0. 207 m in radial orbit component, 2.28 m in 3D position, and 0.25 m in radial orbit component, 2.75 m in 3D position after 1 day of prediction.
