摘　　要：北斗卫星导航系统采用应答式工作体制,我国的长河二号远程导航系统属于罗兰C工作体制。二者均可提供二维导航信息,但将二者组合起来工作,则可为海、陆、空用户提供三维导航定位服务。平稳、准确的时间尺度是导航定位系统的基础,本文介绍了北斗/罗兰C组合导航系统中时间测量系统的原理及实验结果。Beidou satellite navigation system adopts igation system is based on the Loran-C work mode, the responsive work mode, while the Changhe Ⅱ long-range nayboth of them can only provide two-dimensional navigation information. But when Beidou system and Changhe Ⅱ system are combined together, three-dimensional navigation and position services can be supplied to users. Stable and accurate time scale is an important foundation of the integrated navigation system. This paper introduces the principle of time measurement system in Beidou / Loran-C integrated navigation system and the experiment results.
