Improvement of orbit determination accuracy for Beidou Navigation Satellite System with Two-way Satellite Time Frequency Transfer
Chengpan Tang,Xiaogong Hu,Shanshi Zhou,Rui Guo,Feng He,Li Liu,LingFeng Zhu,Xiaojie Li,Shan Wu,Gang Zhao,Yang Yu,Yueling Cao +11 more
TL;DR: In order to improve the orbit determination accuracy for BDS, a new orbit determination strategy is proposed, in which the satellite clock measurements from TWSTFT are fixed as known values, and only the orbits of the satellites are solved.
Journal ArticleDOI
Applications of two-way satellite time and frequency transfer in the BeiDou navigation satellite system
Shanshi Zhou,Xiaogong Hu,Li Liu,Rui Guo,LingFeng Zhu,Zhiqiao Chang,Chengpan Tang,XiuQiang Gong,Ran Li,Yang Yu +9 more
TL;DR: The results show that with TWSTFT clock observations, the accuracy of satellite clock prediction is higher than MPOD, and the BDS clock stability at the 103 s interval is approximately 10−12, which is similar to the GPS IIR.

Orbit improvement for Chang’E-5T lunar returning probe with GNSS technique
Min Fan,Xiaogong Hu,Guangliang Dong,Yong Huang,JianFeng Cao,Cheng-Pan Tang,Peijia Li,Shengqi Chang,Yang Yu +8 more
TL;DR: In this article, the authors analyzed the measurement data of the Chang'E-5T spacecraft for a trial in the Chinese lunar exploration program, and the position error in the one-hour prediction from the orbit determination using GNSS single-difference pseudorange in the 1.5h arc was less than 109m, while that from the result using range and Doppler data in the 3h arc is 369m.

SIS accuracy and service performance of the BDS-3 basic system
Jinping Chen,Xiaogong Hu,Chengpan Tang,Shanshi Zhou,Yufei Yang,Junyang Pan,Hui Ren,YueXin Ma,Qiuning Tian,Bin Wu,Yang Yu +10 more
TL;DR: A comprehensive evaluation of the pseudorange measurement characteristics, signal-in-space (SIS) accuracy of navigation messages and global service capability of the third-generation BeiDou navigation satellite system proves that the BDS-3 basic system has achieved the design goal.
