In the surveillance of aircraft using Automatic Dependent Surveillance (ADS), the extrapolated positions are estimated by using the position data received from each aircraft through a data link and are shown on a display at an air traffic control center. The extrapolation errors affect surveillance accuracy. The authors have reported the characteristics of extrapolation errors in α-β tracking for ADS theoretically and through simulations. In the analysis, we disregarded the effect of transmission delay on the extrapolation errors. In present satellite link for ADS, the transmission delay is not marginal for ADS. This paper describes the extrapolation errors in α-β tracking for ADS when the transmission delay in ADS reporting is included. Theoretical analyses for straight flight showed that the extrapolation errors depend on the ratio of a transmission delay to an ADS reporting interval and that the effect of transmission delay on extrapolation error increases as the value of α approaches 1. Simulation results for curved flight showed that the effect of transmission delay on extrapolation error depends on a course change angle and an ADS reporting interval.
