摘　　要：采用GPS作为单一的导航、定位和授时系统具有危险性,在复杂电磁环境下易受敌方干扰。针对美国关闭罗兰C发射台,分析了GPS拥有备份系统的必要性和罗兰C作为备份的可行性。最后得出结论:我国需要继续保持和发展陆基无线电导航系统。Adopting GPS as single navigation and time service system is dangerous, the system is vulnerable to hostile interference. For the U.S. shut clown Loran-C stations,the necessity of having a GPS backup system and the feasibility of using Loran-C as the backup are analyzed. Finally came to the conclusion that there is a need to continue maintaining and developing land-based radio navigation syseem.
