摘要
随着电子技术与计算机技术的发展,GPS全球定位系统得到了进一步的发展与完善。GPS在全球各领域广泛应用的同时,也成为美军战斗效能发挥不可或缺的利器。本文在分析美军现有GPS系统本身存在的脆弱性以及所面临挑战的基础上,从GPS系统卫星、接收机、地面站、编码等五个方面着重讨论了美军对现有GPS系统的改进与发展情况,最后简单介绍了美军第三代全球定位系统(GPSⅢ)的发展趋势。
With the development of the electronic and computer technology, GPS has made a great progress. GPS has been enhancing the capabilities of US forces. Based on the frangibility of the GPS, the improvement and development of the GPS from satellite, receiver, ground station, coding are discussed.
