摘　　要：实时差分GPS能为海上和陆地用户提供连续的高精度动态定位。本文以ASHTECH-XⅡ型GPS接收机和甚高频(VHF)为数据链组成的实时差分系统为例,讨论了实时差分GPS的原理、系统组成和实现的方法。试验和应用的结果表明,在多数情况下,该系统可以获得优于5m的综合定位精度。Real-Time Differential GPS(RTDGPS) can provide marine and land users with continual navigation and positionging of high accuracy. Using the examples of RTDGPS which is combined with ASHTECH M--XII GPS receivers and VHF radio data chain, this paper will present a discussion on the theory, system composition and implemention of RTDGPS. The experiment and application show that, under most conditions, the system can get positioning synthetiol accu- racy better than 5 meter.
