| Abstract: | 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. |
