摘　　要：GPS-OEM板一般以原始的二进制格式提供导航报文,为了得到最终的定位结果,需要对报文进行解码,获得相关测量量以及卫星参数,再构成计算方程组进行求解。本文提出了一种在WinCE环境下的GPS导航信息处理的软件实现方案,描述了嵌入式处理器与GPS-OEM板的连接方式与串口通信方法,分析了GPS导航电文的格式,最后,设计了导航解算软件流程并给出了解算结果的显示。此设计方案已经在车载导航型GPS接收机的研制中得到应用,工作稳定,并满足精度要求。GPS-OEM board supply the navigation message with bin format, which have to be decoded to acquire the observation value of GPS and parameter of satellite. Calculation equations involving these parameters obtained above must to be solved to get the eventual location results. This paper presents a software solution to GPS message decoding base on WinCE system. Describe the method of series communication and connect mode between embedded CPU and GPS-OEM board. The format of GPS navigation message is analyzed. At last, the compute flow of navigation is designed and the computing results are given. This solution has been used in the research of a navigation GPS receiver with high reliability and good precision performance.
