| 摘 要： | 本文利用地球非球形引力、日月第三体引力摄动分析解理论综合分析了导航卫星广播星历参数设计的物理意义,从理论上确定了其取值范围.并通过＂共振＂效应的综合分析,对GPS开普勒广播星历参数对IGSO、GEO卫星的适用性进行了深入研究,最后通过理论分析指出小倾角、J2,2项共振等因素是引起上述广播星历算法不适用于GEO卫星的主要原因.针对GEO卫星星历参数拟合法方程严重病态以及部分接口参数超限的问题,提出了动态加权的带参数约束条件平差算法.通过实际算例证明,该方法能有效稳定星历拟合结果,解决Δn等星历参数超限的问题.

| Abstract: | The physical definition of navigation satellite broadcast ephemeris parameters are analyzed by the non-spherical gravitational potential and the third body perturbation theory, and their theoretic bounds are concluded. The resonance affection on high orbit navigation satellite is synthetically analyzed, which disturbed the applicability of the Kepler ephemeris fitting arithmetic on GEO, and the i≈0 and J2,2 factors mainly cause the inapplicability. To solve the former problems, an arithmetic named constraints adjustment with parameters dynamic weighting is advanced, which is proved to be effective to stabilize the ephemeris parameters fitting results or to limit all parameters such as Δn within the bounds of the interface. |
