| Abstract | The increasing congestion of commercial airspaces necessitate more efficient Air Traffic
Control (ATC) methods. The Automatic Dependent Surveillance-Broadcast (ADSB) application,
a kind of aircrafts running surveillance technology based on global navigation
satellite system (GNSS), is one of the most applications of ATC systems and is being rolled
out in many countries. The ADS-B data link includes both the air-to-air data and the air-toground
data. Conventional surveillance methods consist of voice reporting, visual checks,
and primary and secondary surveillance radars. Nevertheless these methods are replaced by
ADS-B, a major new technology that is reclassifying the superior of Communications, Navigation,
and Surveillance (CNS) in air traffic management today. Unmanned Aircraft System
(UAS) is an aircraft which is no need human pilot onboard instead, the UAS is managed from
an operator on the ground. As the ADS-B system is replaced in Primary Surveillance Radar
(PSR), ADS-B is applied to UAS. ADS-B provide superior performance in tracking UAS.
The UAS must fly with Instrument Flight Rule (IFR), not with Visual Flight Rule (VFR),
so the role of ADS-B is more important than any other systems. The improved Interacting
Multiple Model (IMM) Kalman filter provides a powerful framework for performing the
tracking of UAS as well as track UAS continually using estimates calculated from the filter
when ADS-B data losses occur. The improved IMM filter is applied to the ADS-B system to
improve the accuracy of the ADS-B data. Then, the comparison of the original ADS-B data
and the ADS-B data with the improved IMM filter prove that the ADS-B data with improved
IMM filter supports the better.
