Abstract
This paper investigates the algorithms needed to compare two tracker outputs running on the same air situation trajectories. Tracking system provides aircraft trajectories containing aircraft kinematics supplemented with additional data. Tracker accuracy performance as well as tracker data output integrity and continuity is essential for controllers and safety nets applications, which guarantee a high safety level. The comparison procedure described in this paper provides tracking performance, automatic detection of tracking anomalies and is performed by considering a tested tracker and a reference. The reference is given by another tracker or a set of trajectories given by a sensor simulator. Results based on live data and simulation scenarios are presented. This method is used for mutual validation between two different types of tracker, perform some regression testing between two releases of the same tracker or assess the tracking performances using a sensor simulator.
