| 摘 要： | 介绍GEO卫星广播星历参数超限的现象和规律,根据解算方程病态性和轨道动力学特性分析该参数超限的原因,设计在不显著损失精度前提下多种改善参数超限的拟合方案,利用实测数据进行试验。结果表明:固定超限参数的同时解算其余星历参数和进行参数岭估计的方法,都能够有效地抑制并解决参数超限问题。

| Abstract: | The phenomenon and regulation of parameter's exceeding limitation in the operation of system are introduced,and then the reasons are illustrated according to the ill-conditioned equation and the orbital characteristics,some fitting algorithms are designed on the condition of avoiding accuracy losing,and the experiments are carried out with the actual observation data.The results show that it is efficient to eliminate the parameter exceeding for the method of fixing one parameter while computing the others o... |
