摘要
北斗和GPS双系统定位具有较强的可靠性和适应性,已广泛应用于我国各种位置服务领域。但是双模定位系统的输出协议和标准的NMEA0183协议相比更加复杂,而且随着当前卫星信号强度的变化,输出的协议帧时多时少,单条协议帧中的数据量时大时小,因此,双模定位系统输出协议帧的有效解析显得极为重要。提出一种新型算法解析这种双模系统中的输出协议帧,此方法成功应用于UM220双模定位模块,实测表明该系统稳定可靠。
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 hybrid 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 system 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.
