| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Wide Area Multilateration (WAM) is an aircraft surveillance system using TDOA. In WAM, GPS is widely used for time synchronization between receiver stations, and it has a vulnerability that the localization function stops at the time of GPS outage. As a countermeasure, there is a method to continue time synchronization using rubidium oscillator. But in this method, there is a challenge that a clock bias error increase with time. On the other hand, there is a TDOA localization which estimates the bias error simultaneously with the position. However, in order to apply this localization to the above challenge, some improvement is required in correcting the estimated error. In this paper, we propose an improvement scheme to apply this localization for bias clock errors in rubidium oscillators. And the evaluation results by the computer simulation are indicated. | |
