| 摘 要： | 地球轨道上数量日益增长的空间飞行物体对在轨航天器及人类航天活动构成了严重威胁。分析了空间目标两行轨道根数(TLE)的格式及构成;阐述了相应的SGP4/SDP4轨道近似解析解模型算法;提供了轨道坐标系和惯性坐标系之间的转换关系;利用TLE数据和SGP4/SDP4模型进行了空间目标碰撞预警计算。该方法对于航天器初步威胁评估具有重要意义。

| Abstract: | The population of space objects in the earth orbit is increasing and these objects have serious hazards to spacecrafts and space activities.The format and composition of two-line element sets were analyzed firstly.And then Simplified General Perturbations Version 4 and Simplified Deep-space Perturbation(SGP4/SDP4) orbital model which developed from analytic orbital theory were introduced.And the coordinate transformation from True Equator and Mean Equinox of Date to Earth Mean Equator and Equinox of Date wa... |
