| 摘 要： | 推导了联合甚长基线干涉测量（VLBI）和天文导航的月球车定位计算公式，并利用嫦娥三号（CE-3）实测数据分别解算VLBI单独定位和联合天文导航定位的月球车定位结果。结果表明，联合定位相对于单独VLBI定位，提高了天文导航的定位精度，改善了月球车的定位精度；同时，联合VLBI和天文导航定位也保障了月球车定位的可靠性与稳定性。 |

| Abstract: | The calculation formula of lunar rover positioning based on VLBI and celestial navigation is presented in the paper. The results of VLBI positioning and joint positioning based on combined VLBI and celestial navigation are calculated with the measurement data of Chang’e-3 (CE-3). This shows that joint positioning can improve the positioning accuracy of lunar rover by celestial navigation or VLBI alone. Furthermore, joint positioning can also guarantee the reliability and stability of lunar rover positioning. |
