| 摘 要： | 基于Lambert方程和空间几何知识,给出了适用于空间监视电子篱笆设备稀疏观测资料轨道确定的方法.通过对大量目标的模拟试验表明,该方法确定的初始轨道能使轨道改进收敛,定轨精度优于100米,证明该方法适用于电子篱笆对绝大部分空间目标观测数据的轨道确定.最后讨论了篱笆布站纬度对定轨应用的影响.

| Abstract: | Based on the comprehension of Lambert flmction and spacial geometry,the orbit determination method is developed by using sparse data of Electronic Fence.Accord- ing to the simulation of massive objects,the process of orbit improvement is successfully converged by taking the initial orbit elements provided by the method,and the orbit de- termination precision is better than 100m.The method is so proved to be effective for the overwhelming majority of objects.At last,it is discussed that the station latitude ... |
