摘 要
本文对 GPS 定位的原理进行了介绍,对定位数据格式进行了研究 ,
并提出了将 GPS 定位导航信息从 GPS 接收机完整接收的方法,通过对
定位参数的提取可将其应用于其他高层应用决策如各种 GIS、RS 系统
等。
随着 GPS 定位技术的不断发展和应用的普及,愈来愈多的 GPS 接
收机及数据处理软件进入我国市场,获得了巨大的经济效益和社会效益。
但是由于各 GPS 接收机的观测数据格式不统一,引起 GPS 数据处理软
件的不通用,为用户的使用带来了困难,同时也为 GPS 数据观测格式
的共享和 GPS、GIS 的集成设置了障碍。因此,研究 GPS 观测数据格式
日趋必要。

ABSTRACT
This paper introduces the theory of GPS positioning system and studies
positioning data form. At the same time ,it puts forward the method for
completely receiving GPS positioning navigation information from GPS
receiver. By abstracting the positioning parameter ,it can be used in other
advanced application strategy such as GIS and RS system and so on.
With the fast development and wide use of GPS, more and more GPS
receivers and data processing software rush into Chinese market and get large
economic and social benefits. However, the incompatibility of the observing
data form of GPS receiverleads to the uncommon use of data processing
software and brings some difficulties to users. Meanwhile it makes the share
of and integration of GPS and GIS difficult. Therefore, the study on GPS
observing data form becomes more and more essential.
Key words: GPS, positioning form, data form extraction
