北斗/GPS双模定位系统协议解析算法研究
Research on protocol analysis algorithm of Beidou/GPS hybrid positioning system
摘要
Abstract
The Beidou/GPS hybrid positioning system has great reliability and adaptability,and is widely used in the fields of various location based service. Compared with the standard NMEA0183 protocol,the output protocol of the Beidou/GPS hy-brid positioning system is more complicated. With the intensity changing of satellite signal,the data size in single protocol frame and the output protocol frame are varied,therefore,the effective analysis of the output protocol frame in hybrid positioning sys-tem is extremely important. A new algorithm which is used to analysis the output protocol frame in hybrid positioning system is proposed. This method was successfully applied in UM220 Beidou/GPS hybrid positioning module. The actual measured results show that the system is stable and reliable.关键词
