RIGOROUS analysis of a collision avoidance system is required before deployment in the
airspace due to the potentially catastrophic consequences of error in their operation. Civil …

(NAS) is an essential but limited resource supporting the vitality of the economy and the
freedom to travel. Use of this resource is stressed, however, by demands placed by …

EXECUTIVE SUMMARY The Traffic Alert and Collision Avoidance System (TCAS) is a
widely-deployed safety system for reducing the risk of mid-air collision between aircraft …

The task of an airborne collision avoidance system is to continuously evaluate the risk of
collision and in the case of too high risk initiate an evasive action. The traditional way to …

This paper presents a new computationally efficient S&A algorithm for implementation in real-
time applications for UAV. Based on a simplified optimisation approach, the proposed …

Integrating unmanned aircraft into civil airspace requires the development and certification
of systems for sensing and avoiding other aircraft. Because such systems are typically very …

An autonomous navigation system integrating both the path following and the autonomous
sense & avoid functions is presented in this article. The sense & avoid algorithm was …

Modeling and simulation for multi-aircraft collision avoidance to understand the mechanistic
behavior is an important activity. Building models using general programming language …

80 eters can then be applied to one or more trajectory predictors of the ground automation
system to predicta trajectory of the aircraft. In certain embodiments, the method and system …

In this article, collision probability between aircraft in uncontrolled airspace is estimated. For
that purpose, a large database of aircraft trajectories in the vicinity of Saint-Cyr-l'Ecole …
