Modeling and Simulation of Collision Avoidance Algorithm for UAV

Current development and operations of Unmanned Aerial Vehicles (UAVs) or drones requires their seamless integration into national airspace systems. The integration should always consider the development and utilization of the UAV’s collision avoidance algorithm and logic. Therefore, concerns about command and control latency, vehicle performance, reliability of autonomous UAV functions, and interoperability of the TCAS (traffic alert and collision avoidance system) and ATC (air traffic control) roles have been subjects of many studies. Nowadays, some areas of airspace are already crowded by continuous operation of commercial aircraft. This paper describes some studies and development of a collision avoidance algorithm using Lapan Surveillance UAV LSU-05 as simulation model. Although the maneuvers are limited to horizontal plane, simulation showed that the algorithm performs very well under given case studies without any disruption to other aircraft operation controlled by the ATC
