Abstract: ADS-B(automatic dependent surveillance-broadcast) is a kind of aircraft surveillance technology basing on GNSS(global navigation satellite system) and aeronautical data link. ADS-B is widely used in en-route, terminal area,airport surface and non-radar area surveillance. To quantitatively evaluate surveillance performance of ADS-B in practice, an ADS-B experimental system is constructed near Tianjin Binhai International Airport. ADS-B message updating period, loss rate, jumping rate and integrity are analyzed by using DF-17 data which is collected by the experimental system. Results show that the ADS-B message updating period is shorter and the loss rate of cruising flight is lower than approaching and departuring flight. Some aircrafts may have jumping points with low jumping rate, and the integrity of position data of ADS-B system is up to 98.8%.

Key words: ADS-B, message update period, loss rate, jumping rate, Kalman filtering, integrity
