目的为了节约测控资源。方法采用天地基测量的卫星星座联合轨道确定,同时阐述了基于星间光学测量的多星精密轨道确定的关键技术,给出了星间光学测量模型及对应的偏导数计算公式,分析了多星联合定轨所面临的主要问题及应对的解决方案。结果实现了真正的多星同步轨道积分。结论对天基监测的非合作目标卫星轨道确定进行了计算分析,为天地基一体化联合多星定轨提供了基础。
The purpose of saving resources for monitoring and control. Methods The satellite constellation joint orbit determination based on space-based surveying was used. At the same time, the key technologies of multi-satellite precise orbit determination based on the inter-satellite optical measurement were described. The formula of the inter-satellite optical measurement and the corresponding partial derivative calculation were given. Joint Orbit Determination of the main problems and solutions to deal with. The result is a true multi-satellite orbital integration. Conclusion Computation and analysis of non-cooperative target satellite orbit determination by space-based monitoring provide the foundation for the integration of multi-satellite orbit determination.
