| 摘 要： | 影响月球探测卫星星地时差的因素较多，文章介绍了其计算模型，并对其中的模糊距离进行了详细分析。通过对试验数据的分析，运用最小二乘法，分别建立了集中校时量和均匀校时量计算模型。实际结果表明：运用此两种校时模型和方法可以方便有效地控制嫦娥一号卫星的星地时差，并使其在一段时期内保持在5ms范围以内。

| Abstract: | There are a lot of factors influencing the time difference of lunar exploration probe.The paper describes the model,and also analyzes ambiguous distance in detail.The paper studies both centralized adjustment model and adjustment model by using the least square method to process the experiment data.The real results show that we can control the time difference of CE-1 conveniently and effectively by using these models and methods,and keep it within 5ms in a period. |
