One of the key problems of unmanned aviation technology is its integration in the airspace system. This topic is a subject of focus of authorities in many countries, but also of international organisations which are searching for universal legal regulations, procedures and systemic solutions. These activities will determine the future of UAS technology development, which is currently strongly hampered, especially in its very promising, commercial sector.

FAA specified new definitions which are supposed to enforce the use of electronic systems installed on the UAS side in the nearest future. They are supposed to guarantee safe airspace sharing in direct surrounding of manned air traffic. Operation of these solutions is based on the proven ADS-B technology (Automatic Dependent Surveillance – Broadcast), which comprises a pillar of a modern air traffic management conforming to the NextGen philosophy (SESAR in Europe).

Designing of sub-miniature anti-collision systems for UAS is extremely complex. Firstly, it involves hardware optimisation on many levels, forcing balancing at the extreme edge of technological capability offered by modern signal processing and by the RF technology. On the other hand, it means a necessity to develop efficient operator interfaces and a scalable autonomy, able to be adapted within the entire spectrum of UAS applications.
