Abstract:
Unmanned Aerial Systems (UASs) have become enormously popular as they improve many applications like structural inspections, homeland security, delivering packages, etc. UASs share the same airspace as manned aircrafts and thus autonomous UAS operations and current airspace management has to be integrated. It is recognized that the use of small UAS and taxi-drone at lower altitudes is now a driving force of economic development, but a safety risk when its number increases. UAS will fly and make decisions autonomously using only on-board sensors and processors. As the number of simultaneous UAS flight increase, keeping a safety airspace is a challenge that implies that UAS navigation autonomy must be verified for conflict avoidance in high density air traffic areas. The required scenarios to verify air traffic management algorithms and autonomous capabilities of UAS are complex to deploy and UASs may collide, therefore simulations are of great importance. This paper presents a conflict simulator of multiple UASs with different equipment. The main purpose of the simulator is to verify UAS subsystems, like collision avoidance, in different scenarios with a combination of different equipped UASs and flight plans. To evaluate its effectiveness, it has been performed an integrated simulation process for a Collision Avoidance Systems (CAS) implementation where Hardware In the Loop (HIL) and software simulations are combined to improve UAS subsystems safety and to reduce the time-to-market.
