摘　　要：编队飞行卫星间的距离和时间差测量是实现分布式航天器,完成特定任务的重要基础。在介绍双向单程距离与时差测量系统的基础上,提出测量系统的一种在系统整体零值标定方法,按照天线是否在系统连接,设计了有线对接标定和无线对接标定两种方式。经理论分析和实际应用,表明所测数据稳定、结果可信。文中所提方法可作为一种新的系统零值标定方法,适用于双向单程距离与时差测量系统的出厂标定,系统零值标定的标准不确定度优于0.47ns。The inter-satellite ranging and timing is important foundation of distributed spacecrafts for specific task. The system and its in-system integrated delay calibration method on inter-satellite dual one way ranging and timing are presented. In this paper, the measurement uncertainty of the method is deduced and analyzed in detail. And the theoretical analysis and application demonstrate that its result is creditable. The delay calibration method adapts to in- ter-satellite dual one way ranging and timing system and the uncertainty of calibration measurement can be less than 0.47ns.
