基于OEM板的GPS定位接收机的研究与实现

Design and Implementation of a GPS Receiver Based on GPS-OEM Board

全球定位系统 (GPS)已在定位、导航、精确授时等领域得到了广泛应用。利用GPS的原始设备制造商 (OEM)板与计算机、通信等技术相结合 ,用户能够自主、方便地开发出各种满足特定需求的GPS应用系统。以GARMIN公司的GPS 2 5板为例 ,介绍了GPS OEM板的内部结构、功能和对外接口 ;以实例的方式给出基于OEM板的GPS定位接收机的硬件电路设计、器件选择和软件设计等技术方案。系统实现的结果表明该接收机应用效果良好。

GPS has been widely applied in the fields such as location, navigation and precise time-giving. By integrating the GPS-OEM board and the computer and communication technique, the users can develop many kinds of GPS application systems freely and expediently for their special purposes. Taking the GPS-25 board of the GARMIN company as example, the internal structure, function and interface of the GPS-OEM board are introduced. Besides, the design of the hardware, the selection components and design of software of the GPS receiver are also given through example. The test result shows good effect.
