Integration of UAV in Flight and Ground Operations

Abstract

Advances in technology have partially ameliorated the increasing workload on air traffic controllers due to the tremendous volume of air traffic. However, higher level automation will be necessary, especially considering increasing pressures on current airspace architecture by unmanned aerial vehicles (UAVs). Here we present a relatively inexpensive, modular, and wireless networked airspace. We present the system as a test bed for the implementation of a distributed airspace system, and any associated ground based or airborne algorithms. As a proof of concept, we outline a procedure for the automated generation of airspace trajectories and prediction of future aircraft position using a ground based neural network model. Based on trajectory information predicted by the neural network, it would be possible to predict and collisions and perform collision avoidance maneuvers. The technology is a potential tool for the simulation of novel air traffic control algorithms. Flight tests using household electronic equipment and small RC airplanes have been used to demonstrate the system's functionality.

Flight Testing a UAV in Simulated Controlled Airspace

“…These flight controls are shown in order to explain the reasoning behind our design and also give a glimpse into the rationale behind our entire simulated airspace. 21 In Tables 1 and 2 the aerodynamic coefficients, derived from aircraft geometry, are presented. These are used to calculate stability derivatives for the initial aerodynamic model.…”

“…Towards this end, we can very easily mimic an ADS-B infrastructure, which lends itself to the autonomous and adaptive arrangement as discussed: the iPhone possesses GPS for location reporting and WiFi which can serve as the datalink. 21 All of our control laws are designed to maintain stability and control the intricate portions of flight, while allowing the macro portions of the flight plan be controlled by the UAV operator through a predictable and simple GUI.…”
