The project TDAAS included research and development of the new anti-collision system Detect and Avoid, providing mid-air collisions protection in the manned aviation and also in the area of the unmanned aerial systems. The project goal was to survey and develop the algorithms, architecture and demonstrator of the anti-collision system, which would bring new knowledge essential for the safety in the small aviation improvement and enabling integration of the UAS into civil non-segregated airspace.
