中文摘要：

通过对利用c波段转发式测轨网观测“鑫诺一号”卫星得到的原始资料进行初步分析，探讨卫星轨道机动时卫星在测站与卫星连线方向的距离、速度和加速度的变化规律，并提出一种通过对原始观测数据的拟合比对，实现GEO卫星（地球同步卫星）轨道机动检测的方法。分析比较表明，用该方法检测到的卫星机动开始和结束时刻与星载推力器实际喷火开始和结束时刻之间的差别小于3min，该方法对处于机动期间的轨道确定有一定的积极意义。

英文摘要：

The variation regularities of the distance between satellite and observation station as well as the velocity and acceleration in the direction from satellite to observation station are discussed based on an analysis of the original observation of the GEO （geostationary earth orbit） satellite SINOSAT-1, which has been obtained from C band orbit measuring net. A method to monitor orbit maneuver is put forward by comparing and fitting the original observations in order to realize maneuver monitoring for GEO satellite. Analyses and comparison show that the difference between the detected maneuver time obtained with the method presented in this paper and the true maneuver time provided by the satellite company is less than three minutes, and the method is of certain significance for satellite orbit survey.
