| Abstract: | The location technology based on cells and satellites is widely paid attention today. In this paper, a comparison for TDOA location technology of the base station with that of synchronous satellite is firstly given. Then, the algorithms for two location technology are presented, respectively, and their performances are evaluated and analyzed. The conclusions show that the basic location principle of the two TDOA location methods is the same and each has its advantages and shortages. They should be combined to meet the different situations in application. |
