| 摘 要： | 基于北斗监测接收机提供的众多数据，选择了3种数据组合方案，分析不同数据源对卫星精密定轨的影响。首先，介绍了采用的定轨策略和3种数据组合方案，然后，从定轨残差和重叠弧段分析了不同方案的定轨精度，最后，对3种方案的定轨结果两两作差比较其精度。分析结果表明，采用方案二和方案三的定轨精度略优于方案一。

| Abstract: | In order to analyze the effects on satellite orbit determination by different data sources, three kinds of data combination schemes are selected, based on many data from Beidou monitoring receiver. Firstly, orbit determination method and three kinds of data combination schemes are introduced. Then, the orbit determination accuracy of different schemes is analyzed from the orbit residuals and overlapping arcs. Finally, the precise orbit accuracy is analyzed through comparing of three kinds of schemes. The resuhs show that the precision orbit is slightly better by using schemes two and three than that of scheme one. |
