近圆轨道遥感卫星星下点轨迹的计算

Calculation of Subsatellite Track of Remote Sensing Satellite in Nearly Round Orbit

根据遥感卫星轨道的特点 ,提出了计算近圆轨道卫星星下点轨迹的算法 ,并对其进行了精度评估。结果表明这种算法是快捷和有效的 。

Based on the facts that the orbit of Remote Sensing Satellite is nearly round, a new method of calculating the subsatellite track of this satellite is put forward in this paper, and the precision of the algorithm is evaluated at the end of it. The result shows that this method is fast and effective and thus can meet the demands of orbit accuracy during satellite design.
