摘要
研究了BD970板卡的支持多星多系统的RT27观测数据格式的解码,并与天宝接收机自身解码结果进行对比,两者解码结果一致。在此基础上自主开发了基于RT27和IGS(international GNSS service)RTS(real-time service)的实时精密单点定位(precise point positioning,PPP)程序,并对其性能进行了评估与分析,结果表明,无论静态或动态解算均能达到cm级精度,验证了该实时PPP程序的可靠性和精确性。
In this paper,we study the decoding of RT27 data which supports multi-system based on the BD970 board,and find the results based on our decoding program are essentially in agreement with these based on Trimble decoding program.Meanwhile,we develope a real-time precise point positioning(PPP)based on RT27 and IGS(international GNSS service)RTS(real-time service),whose performance is evaluated and analyzed,and the results of statistical and kinematic solutions confirms that both can achieve centimeter-level accuracy,which proves the reliability and accuracy of our real-time PPP program based on RT27.
