导航定位设备除用于定位导航外,全球定位系统接收机也能嵌入无线电台,使其成为通信—导航综合系统。手提式特高频无线电台由玛格纳沃克斯电子系统公司研制,包括一部6信道连续跟踪的全球定位系统接收机和电池组,重量小于1.4公斤。该电台采用直接扩频与跳频相结合的波形,信号猝发时间仅约0.3秒,以便使被敌方截获和检测的概率减到最小。全球定位接收机还具有以被动方式接收信息的能力,由于它的覆盖面积大,从而
In addition to navigation and positioning equipment used in positioning navigation, the GPS receiver can also be embedded in radio stations, making it a communication - navigation integrated system. Portable VHF radios, developed by Magnus Vaux Electronic Systems Inc., include a 6-channel continuously tracked GPS receiver and battery pack weighing less than 1.4 kg. The radio uses a combination of direct spread spectrum and frequency hopping, with signal bursts of only about 0.3 seconds to minimize the probability of interception and detection by the enemy. Global positioning receivers also have the ability to receive information passively, because of its large coverage area
