| 摘 要： | 为了提高我国卫星导航系统GEO卫星定轨能力,针对我国卫星导航系统所特有的新数据和新方法,利用CAPS系统的C波段转发式测距数据进行了单GEO卫星定轨实验.在分析该方法技术特点的基础上,从定轨残差和轨道重叠弧段比较等方面,对定轨结果进行了分析.由于设备转发时延是影响该方法定轨精度的重要因素,因此同时还分析了系统偏差对定轨精度的影响,得出了一些有益的结论.

| Abstract: | CAPS is a new kind of methods of our country’s navigation system.And CC transfer observation is a new kind of data of CAPS.In order to improve GEO satellite orbit determination ability of our country,single GEO satellite orbit determination experiments were done in this paper using this new method and new data.Based on technique characteristics analyses,orbit determination results were analyzed through orbit determination residuals orbit overlap arc and so on.Due to device delay was an important factor for the precision of this method,the influence of systematic error on orbit determination precision was analyzed.And some useful conclusion are educed. |
