It is to be expected that space robotics systems will develop more and more in the future spatial applications. One of the most challenging and risky missions for spacecraft is to perform autonomously Rendezvous and Docking (RvD) in space. This paper

Aircraft and algorithms used in automated flight control are always designed for calm atmospheric conditions; therefore, testing their behaviour in realistic atmospheric conditions implies the necessity for efficient turbulence models. The present pa

Rendezvous process of spacecrafts is one of major issues in study of aerospace engineering. Tracking control in Rendezvous process is very complex due to the need to fulfill the conditions and constraints to determine the control forces to bring Chas

An important element that interacts unfavorably with pilot and aircraft is the triggering event. Without a trigger event (or a chain of triggering events) A/RPC does not appear. This study presents an overview of different classes of triggers that ca
