摘　　要：基于对GPS应用广泛性的思考,设计并实现了一套验证GPS定位功能的原型系统。首先介绍了GPS定位相关原理、GPS通信协议和Windows CE操作系统内核映像定制步骤,然后依据GPS通信协议语句特征,提出一种GPS信息域获取方法,最后阐述了验证系统的GPS定位软件的关键部分的实现。此系统正确地验证了GPS定位功能,也证明所提出的GPS信息域提取方法的可行性。Based on extensiveness of GPS application, we designed and implemented a prototype verification system verifying positioning- of GPS. This paper at first presents related principles about GPS positioning and, communication protocol and customization of windows CE OS kernel. And then brings forward an way of extracting GPS information according to the feature of GPS protocol sentences, and at last details key part of positioning software of GPVS. This system verifies correctly how GPS application system works, which also suggests that the way of our extracting GPS information is also feasible.
