2022年外军定位导航与授时领域发展综述

Overview of the Development of Foreign Military Positioning,Navigation and Timing in 2022

以美国为首的世界军事大国仍以提升对抗环境下的弹性定位导航授时能力作为发展目标。在系统和技术发展方面,持续推进导航卫星的升级换代和卫星导航新技术的验证,发展卫星导航拒止环境下的其他可替代PNT技术,并探索研究装备技术。在装备部署和运用方面,基于多导航源融合应用进入装备试装和能力验证。

The world's major military powers such as the United States,still focus on improving the ability of resilient positioning,navigation and time(PNT)service in the adversarial environment.For the system and technology development,the major nations with Global Navigation Satellite Systems continue to promote the upgrading of satellite and the verification of new satellite navigation technologies,and simultaneously develop other alternative PNT technologies in the GNSS denied environment to provide complementary and backup to satellite navigation capabilities.For the equipment deployment and application,equipment trial assembly and capability verification are based on multi-PNT source fusion application.
