| 摘 要： | 随着人类空间活动的急剧增加,同步轨道资源已变得十分稀缺。为此人们采用了多星共位技术,来充分挖掘同步轨道资源。多星共位中,由于卫星存在位置漂移的情况,安全问题成为维护卫星正常工作必须考虑的问题之一。考虑到同步卫星的轨道特性,常采用三程测距的方式对卫星进行测轨,而且需要较长时间的测轨弧段。连线干涉测量可以获得高精度的差分相位时延,这对卫星在垂直视线方向上构成了很强的约束。给出了连线干涉测量系统设计及测量数据处理方法,并对测量中的关键技术与设备特性、测量数据精度进行了初步分析。

| Abstract: | The orbit resource of the geostationary satellite is becoming scarce with the increase of the human's space activity.The technology of multi-satellite sharing one orbit area is used.In the collocation satellites observation,the safety among the satellites is one of the most important problems that need to be solved.Three-way ranging measurement is always used.But it needs a long period of observation in order to get an accurate orbit. The differential phase delay can be obtained with high accuracy in connec... |
