摘要
本文研究了国产GNSS接收机板卡与计算机间的串口通信技术,探讨了板卡NMEA0183协议解析步骤,提出了基于定位精度、稳定性和冷热启动效率等指标的板卡定位性能判别方法,基于Matlab编程测试了司南K500板卡的定位性能,得出了有益的结论。
The serial port communication between the domestic GNSS board and the computer is studied and NMEA-0183 protocol for GNSS board is analyzed in this paper.With the positioning performance indexes of GNSS board introduced,the accuracyof positioning,the stability of positioning,the hot efficiency and the cold starting efficiency are selected to test the positioning performance of GNSS board and the testing methods are suggested.Through experiments based on the Sinan K500 board,some useful conclusionsare made.
