摘　　要：目前,罗兰-C远程导航系统的用户设备(罗兰-C接收机)开始采用可同时搜索、跟踪多个不同罗兰-C台链台站信号的多台链接收机结构。多台链罗兰-C接收机运用"多位置线定位解算技术",利用双曲线定位原理优选多条双曲线位置线进行时差转换定位,基于多台链概位解算和迭代定位解算原理消除定位多值性,提高定位精度。简要介绍了某航空型多台链罗兰-C接收机工作原理,重点对其多台链概位解算和迭代定位解算的计算方法进行了理论研究分析。At present,LORAN-C receivers,as LORAN-C longrange navigation system′s user equipments,began to use multiple station-chains receiver structure,which can search and track a plurality of different LORAN-C station-chains′ signals simultaneously.Based on the principles of hyperbola location solution,multiple station-chains probable position solution and terative positioning solution,using multiple position-lines positioning calculation technology,a multiple station-chains LORAN-C receiver can eliminate multiple values,improve the positioning precision.After a brief introduction of working principle of aviation type multi-station chains LORAN-C receiver,the probable position solution of multiple station-chains and the terative positioning solution algorithms were analyzed.
