Aircraft Tracking Using Automatic Dependence Surveillance – Broadcast

Using Automatic Dependent Surveillance-Broadcast Data for Monitoring Aircraft Altimetry System Error

Altimetry System Error (ASE) is a measure of the height-keeping performance of an aircraft. In airspace where the Reduced Vertical Separation Minimum (RVSM) is applied, the importance of accurate aircraft height-keeping is magnified. ASE is not detectible in routine operations; specialized measurement equipment is necessary to independently measure the errors. To be eligible for RVSM operations...

Automatic Dependent Surveillance-Broadcast for Sense and Avoid on Small Unmanned Aircraft

This paper presents a time-based path planning optimizer for separation assurance for unmanned aerial systems (UAS). Given Automatic Dependent Surveillance-Broadcast (ADS-B) as a sensor, position, velocity, and identification information is available at ranges on the order of 50 nautical miles. Such long-range intruder detection facilitates path planning for separation assurance, but also poses...

Multisensor Surveillance for Improved Aircraft Tracking

Cross-range measurements of aircraft travelling at distances of 50 to 200 miles include significant errors. Therefore, heading estimates for medium-to-long-range aircraft are not sufficiently accurate to be useful in conflict-detection predictions. Accurate crossrange measurements can be made-by using two or more sensors to measure aircraft position-but such measurements must compensate for the...

Automatic Player Detection, Labeling and Tracking in Broadcast Soccer Video

Automatic player detection, labeling and tracking in broadcast soccer video are significant while quite challenging tasks. In this paper, we present a solution to perform automatic multiple player detection, unsupervised labeling and efficient tracking. Players’ position and scale are determined by a boosting based detector. Players’ appearance models are unsupervised learned from hundreds of s...
