Abstract
Automatic Dependent Surveillance-Broadcast (ADS-B) is one of the key available technologies for aircraft surveillance. ADS-B provides high accurate GNSS positions with high update rate for air traffic control and airline operations. This feature will improve the safety and efficiency of air traffic operations. However, ADS-B user cannot benefit from the accuracy capability because the ADS-B message does not include information of GNSS measured time and because of the latency between the GNSS measured time and ADS-B message arrival time. In this paper, we propose a technique to estimate the variable element of ADS-B latency. Then, the proposed technique is applied to real data obtained by ENRI experimental system. The results of the estimations are presented in support of performance assessment.
