Advancements in automation and artificial intelligence are driving the market for fully autonomous drones, which are capable of complex tasks without direct manual control or intervention. Experts believe that these innovations and advancements will blur the lines between UAVs and fully operational unmanned aerial systems (UAS). Topics include autonomous operations, sensing and monitoring, logistics, defense, and the growing role of Integrated Sensing and Communications (ISAC) for drone detection, tracking, and airspace awareness. Exploring key use cases, regulatory considerations, and technical hurdles shaping the future of autonomous UAS and how to detect and track potential hostile drones and drone swarms.
