在引入量子纠缠的二阶相关测距原理的基础上，将量子测量的概念引入到卫星动态精确定轨中。在应用传统定轨模型修正卫星内部系统误差的基础上，建立了相应的量子定轨模型。本文首先利用北斗卫星导航系统（BDS）模拟1天弧长的量子观测，对QOD进行了实验。然后对卫星轨道进行解析，并与参考精确星历表进行比较。随后，讨论了影响QOD精度的相关因素。此外，GEO、IGSO和MEO卫星的精度分别比实测数据分辨率提高了约20倍、30倍和10倍。因此，可以预期，量子技术也可能给卫星定轨带来其他领域已经出现的惊喜。
After the presentation of second-order correlation ranging principles with quantum entanglement, the concept of quantum measurement is introduced to dynamic satellite precise orbit determination. Based on the application of traditional orbit determination models for correcting the systematic errors within the satellite, corresponding models for quantum orbit determination (QOD) are established. This paper experiments on QOD with the BeiDou Navigation Satellite System (BDS) by first simulating quantum observations of 1 day arc-length. Then the satellite orbits are resolved and compared with the reference precise ephemerides. Subsequently, some related factors influencing the accuracy of QOD are discussed. Furthermore, the accuracy for GEO, IGSO and MEO satellites increase about 20, 30 and 10 times, respectively, compared with the results from the resolution by measured data. Therefore, it can be expected that quantum technology may also bring delightful surprises to satellite orbit determination as have already emerged in other fields.
