美国从1974年开始执行了一项分三个阶段到1987年完成的导航星全球定位系统(GPS)计划。1978年当第一阶段计划将要结束的时候,空间与导弹系统机构曾经在尤马试验场对GPS系统做过多次试验。这些试验包括一些装在2.5吨M-35卡车、吉普车和装甲人员输送车中的便携式GPS接收机的试验。另外还包括一些装在飞机和直升飞机上的GPS接收机的试验。 GPS用在军用地面车辆上的优点是: (1)GPS覆盖全球; (2)车辆上的GPS设备是被动式的,车辆不发射无线电信号;

Since 1974, the United States has implemented a navigation satellite global positioning system (GPS) plan in three phases and completed in 1987. When the first phase of the plan was about to end in 1978, the Space and Missile Systems Agency had conducted numerous tests of the GPS system at the Yuma test site. These tests included trials of portable GPS receivers in 2.5-ton M-35 trucks, jeeps and armored personnel carriers. Also included are some GPS receivers installed on airplanes and helicopters. The advantages of GPS on military ground vehicles are: (1) GPS covers the whole world; (2) GPS devices on the vehicle are passive and the vehicle does not transmit radio signals;
