多频同波束VLBI是指两个分离角较小的探测器利用接收天线主波束同时观测。在同波束VLBI中,可以以几个皮秒的小误差获得两个探测器和两个接收望远镜之间的差分相位延迟。差分相位延迟作为同光束VLBI的可观测量,给出了两个探测器在天球上的分离角信息。利用中国4个VLBI站获得的微分相位延迟,可以精确确定距地球3.8×105km的天平面上的二维相对位置,误差小于1m。当月球车和着陆器附近的月球地形能够以10 m的误差确定时,利用差分相位延迟数据和着陆器的距离数据可以确定月球车在月球表面的相对位置,误差为10 m。
Multi-frequency same-beam VLBI means that two explorers with a small separation angle are simultaneously observed with the main beam of receiving antennas. In the same-beam VLBI, the differential phase delay between two explorers and two receiving telescopes can be obtained with a small error of several picoseconds. The differential phase delay, as the observable of the same-beam VLBI, gives the separation angular information of the two explorers in the celestial sphere. The two-dimensional relative position on the plane-of-sky can thus be precisely determined with an error of less than 1 m for a distance of 3.8×105km far away from the earth, by using the differential phase delay obtained with the four Chinese VLBI stations. The relative position of a lunar rover on the lunar surface can be determined with an error of 10 m by using the differential phase delay data and the range data for the lander when the lunar topography near the rover and the lander can be determined with an error of 10 m.
