英文摘要	GPS是全球定位系统（Global Positioning System）的缩写形式，它是一种基于卫星的定位系统，用于获得地理位置信息以及准确的通用协调时间。 GPS进入民用之后，GPS终端产品成了当前GPS市场的主要内容。手机的蓬勃发展，以及它的移动、灵活等特点，与GPS的结合成了当前GPS市场的一个亮点。随着无线移动位置服务技术的成熟和发展，在不远的将来，人们就可以享受到多种多样的LBS（Location-Based Service基于位置的业务）服务。 如何在基于Windows Mobile操作系统的智能手机上实现GPS功能？构件基于Windows Mobile操作系统的手机GPS模块，硬件是基础，Windows Mobile操作系统是软件的运行平台，它们在整个GPS手机中占有重要的地位。因此，本文对手机GPS模块的硬件平台、Windows Mobile 操作系统进行了重点研究。 论文首先分析了国内外GPS发展现状及发展前景，介绍了GPS的原理，并描述了课题的研究目的。本文所设计的GPS手机选择了SiRF公司的GPS方案，按照该方案完成了硬件设计。论文分析了CPU芯片（Samsung公司的S3C2442B）以及SiRF公司GPS芯片（SiRF Star3f/LP）的特点，重点完成了射频前端电路、接收机部分电路、参考时钟电路、电源电路、控制和数据信号电路的设计。同时研究了Windows Mobile的串口驱动模型，完成了串口驱动，实现了CPU与GPS模块之间的串口通信。为了提高GPS模块的TTFF（Time to First Fix，首次定位时间），SiRF公司提供了AGPS（Assisted GPS，辅助GPS定位系统）的解决方案——CLM（Client Location Management，客户机位置管理），因GPS驱动要占用物理串口，本课题通过虚拟驱动，完成了CLM功能，实现了AGPS方案。 论文最后进行了总结，指出了不足之处，提出了改进方法，并展望了今后的发展方向。; GPS is the abbreviation for the Global Positioning System. It is the satellite system which can be obtained the information of geographic position and accurate time. After business usage of GPS , GPS terminal system is to be the main product in the GPS market.The flourishing of mobile phone and its portable、agile characteristic makes the combine of GPS and mobile phone which increase rapidly in GPS market. In the near future, along with the mature and development of the wireless mobile position services technology, people can enjoy various LBS (Location Based Service). How to realize the GPS function on the smart mobile phone based on Windows Mobile operating system? Building the GPS module of the mobilephone based on Windows Mobile Operating System, hardware is the basis, and the windows mobile operating system is the platform for software. They played an important role in the whole GPS mobile phone. So, this paper focus on the study of hardware platform and Windows mobile operating system. Firstly, the paper briefly analyzed the GPS development status quo and prospect at home and abroad, then introduced the fundamental of the GPS, and described the research purpose of the subject. This mobilephone choose the GPS solution of SiRF Corporation, and we designed the hardware system according to the solution. This paper analyed the CPU chip (S3C2442B of Samsung) and GPS chip ( SiRF Star3f/LP of SiRF Corporation), and finished the circuits design, such as the front part of RF, receiver, RTC, power, controlling and data signal part .We research the Serial Port Driver model of the windows CE, finish the Serial port Driver, realize the communication between the CPU and GPS module. For shorting the TTFF (time to first Fix), SiRF Corporation provide the AGPS(Assisted GPS ) solution—— CLM（Client Location Management）.Because the physical Serial Port was occupied by GPS, this subject fulfill the CLM function through virtual Serial Port to realize the AGPS solution. Finally, the paper summarized the work of system design, figured out the deficiencies and improvements, and the future development direction.; 学位：工程硕士; 院系专业：软件学院_软件工程; 学号：2005230044
