In 2020, all airplanes flying above 10,000 feet are required to be equipped with an Automatic Dependent Surveillance Broadcast (ADS-B) transponder to broadcast their on-board estimated position. The addition of transponders on aircraft adds a two-way communication between the radar facility and airplanes which allows for very accurate position estimation and benefits decision making at control centers. The capability as well as complexity of air traffic/surveillance radars have increased significantly over the past decades. Airport control towers are responsible for monitoring and handling the immediate vicinity of the airport while Air Route Traffic Control Centers (ARTCC) are responsible for long range en-route surveillance across various regions that compose the national airspace. An air traffic control system is a complex multilevel system. Commercial flights are usually tracked at all times, from their departure airport to arrival. In the United States, the Federal Aviation Administration (FAA) is responsible for the regulation of thousands of flights everyday across the entire national airspace. You use a multi-object tracker to estimate the plane trajectory, compare the tracking performance, and explore the impact that ADS-B provides on the overall tracking quality. You use two different models to generate synthetic detections of the airplane: a monostatic radar and ADS-B reports. This example shows you how to use an Earth-Centered trackingScenario and a geoTrajectory object to model a flight trajectory that spans thousands of kilometers.
