| 摘 要： | 2010-10-03~2010-10-04,在嫦娥二号任务实时观测阶段进行了X波段测控体制试验。从定位归算角度对试验期间的S波段数传信号(S1频点)测量时延(S1时延)和X波段单程测距差分(DOR)信号测量时延(DOR时延)进行了比对分析。初步结果表明,DOR时延的实测资料精度与链路计算理论估值基本相符。而且由于信号的频带较宽,DOR时延弥散度和定位结果弥散度均优于S1,基线时延闭合差也小于S1。这表明此次试验观测是成功的,为后续探月任务储备了关键技术。

| Abstract: | Two experimental sessions of the X-band monitoring and control system were conducted on 3 and 4 October 2010 during the real-time monitoring stage of the Chang'E-2 Project.Via positioning reduction of the satellite,the experimental observations of the VLBI delays by tracking data transmission signals at S-band(S1 delay) were compared with those by tracking the differential one-way range(DOR) signals at X-band(DOR delay).Preliminary results showed that the observation precision of the DOR delay was consisten... |
