摘要
我国绕月探测工程“嫦娥一号”卫星将以统一S波段（USB）为主，辅以甚长基线干涉仪（VLBI）测轨分系统来完成测控任务。由于“探测一号”卫星轨道与“嫦娥一号”调相轨道段相似，有关单位于2005年3月17日-20日进行了USB和VLBI联合跟踪“探测一号”试验。通过对联合测轨数据的处理，研究了USB—VLBI联合定轨方法，分析了联合定轨和预报精度，得出了一些结论。
Chang＇E-1, China＇s first lunar exploration project, will mainly make use of a Unified S-Band （USB） TT＆C network to provide measurement and control of the spacecraft with Very Long Baseline Interferometry （VLBI） as a complement. Because the orbit of TC-1 satellite is similar to Chang＇E-1＇s phasing orbit, the test on USB and VLBrs joint tracking of TC-1 was carried out in China on March 17-20, 2005. Through data processing, we investigated the method of orbit determination by combining USB and VLBI, analyzed the precision of orbit determination and orbit prediction, and came up with a useful conclusion.
