概述 GPS是英文 Navigation Satellite Timing and Ranging G| obal Positioning System的缩写,意为利用卫星导航进行 测时和测距,以构成全球卫星定位系统。是美国国防部主要 为满足军事部门对海上、陆地和空中设施进行髙精度导航 和定位的需要而建立的。自1973年美国军方批准成立联合 计划局开始GPS的研究工作到1993年系统建成该工程历时 20年,耗资300亿美元,成为继阿波罗登月计划和航天飞 机计划之后的第三项庞大空间计划。它从根本上解决了人 类在地球上的导航和定位问题,在军事和工农业等领域得 到了广泛的应用。给导航和定位技术带来了巨大的变化
