公路-机动型可能精度较低,但是能通过增加卫星导航和部署能力来改进,像通过美国的全球定位系统(GPS)或俄罗斯的全球轨道导航卫星系统(GLONASS)部署到发射平台。
The road-mobile variant might have a lower accuracy but this can be improved by adding satellite navigation and positioning capability such as GPS or GLONASS to the launch platform.
这个雷达系统,被称为合成孔径雷达或简称SAR,是用来弥补全球卫星定位系统的。卫星系统监听失事飞机或者被困人员所发出的紧急呼叫信号。
The radar, called synthetic aperture radar or SAR, is meant to complement a global satellite system that listens for electronic emergency beacons sent by wrecked planes or people in distress.
在全球定位系统信号不可见的情况下,可使用伪卫星系统扩展其使用范围,全球定位系统信号发生器是其中的关键组成设备。
GPS pseudolites systems were employed to extend the availability of GPS when satellites signals were not seen. GPS signal generators were the core part of pseudolites system.
