摘　　要：在“嫦娥五号”任务中,深空干涉测量系统正式参加轨道测量,提供了高精度的角位置信息。采用对流层时延混合建模技术,确保了实时干涉测量精度;利用分时跟踪技术,在链路带宽受限条件下首次开展了快速洲际干涉测量;通过对“嫦娥五号”探测器轨道测定结果分析,表明干涉测量误差修正、定轨精度符合给定的要求,验证了深空干涉测量在深空导航中探测器快速轨道确定的有效性。China’s deep space interferometry system has participated in orbit measurement for the Chang’E-5 mission officially,which has provided high-precision angular position information.The tropospheric delay hybrid model was proposed to ensure the accuracy of real-time interferometry.Using the non-continuous tracking technology,fast intercontinental interferometry was carried out for the first time,which provided high-precision angular position with the advantage of baseline length.The performance was evaluated based on the orbit measurement results of Chang’E-5 probe.These results show that the deep-space interferometry system has played an important role in the fast orbit determination.
