中文摘要：

随着计算机技术、通信技术和信息技术的不断发展，各个行业已逐渐认识到了利用这些高新技术来实现高速采集、处理数据和精简工作任务的巨大潜力。美国建立的全球定位系统作为一种精密的授时、测距、导航、定位系统，已经开始在军事、交通等领域得到越来越广泛的应用。但如何将GPS技术与现代计算机技术有效地结合起来，以实现快速、准确的定位，始终是研究的热点问题。本文介绍了GPS—OEM板的组成和特点，分析了NMEA-0183语句的数据格式及信息组成，重点介绍了基于VC＋＋的GPS—OEM板与PC机的串口通信的关键算法，实现了GPS—OEM板和PC机的串行通信。

英文摘要：

With the development of computer, communication, and information technologies, the great potential of using these new technologies to accomplish high-speed data collection, data processing, and workload reducing is being recognized. As a kind of new timing, measuring distance, navigation and positioning system, the technology of GPS is gradually used in military, traffic and other fields. Aiming at the hot issue of research that how to effectively combine GPS technology with modern computer science to realize rapid and precise position, the paper analyses the data formats and information construction of NMEA-0183 sentence. It also introduces the characteristics of GPS-OEM board, especially introduces the key-arithmetic of serial communication between GPS-OEM board and Personal Computer based on vc ＋ ＋. Then, it realizes the serial communication between GPS-OEM board and Personal Computer. The study is widly applied in navigation and position system by GPS.
