This seminar explores the critical issues and challenges faced in co-operative UAV missions, such as search and rescue, combat operations, and agricultural applications. Key topics include command and control communications, the need for reliable communication infrastructure, and the complexities of mission planning and navigation. Insights from recent studies on communication limitations in urban environments and the implications of operating mixed unmanned and manned systems are discussed. The session concludes with remarks on regulatory considerations and future directions for UAV communication technologies.

Large area: search and rescue • Need to communicate with central command IET Seminar on Communicating with UAVs
Combat Missions [3] IET Seminar on Communicating with UAVs
Combat Missions • Search and destroy • Combat search and rescue IET Seminar on Communicating with UAVs
Urban [1] IET Seminar on Communicating with UAVs
Urban • Need to use existing communications • Results of US study • Is a communication infrastructure even in place? IET Seminar on Communicating with UAVs
Agriculture, remote sensing, survey etc. [4] IET Seminar on Communicating with UAVs
Agriculture, remote sensing, survey etc. • Must use licensed frequencies • Need for low cost solutions IET Seminar on Communicating with UAVs
UAV Formation Flying/Refueling [2] [5] IET Seminar on Communicating with UAVs
UAV Refueling • Piloted tanker-to-UAV • UAV tanker-to-piloted aircraft • UAV-to-UAV • Multiple UAV refueling • Very close co-ordination required IET Seminar on Communicating with UAVs
The Challenges • Autonomous navigation • Complex and dynamic mission planning • Collision and obstacle avoidance • Task allocation and dynamic reconfiguration • High level control and co-ordination of flight operations • Mixed assets and human interaction • Close formation flying IET Seminar on Communicating with UAVs
The Issues • Communications: need to work within national regulations • Allowable frequencies and powers different in different regions • Severe limitations on range • Problems in urban environments – interference (results of US study) • Ad hoc comms networks IET Seminar on Communicating with UAVs
Mixed manned/unmanned systems • Need for C3 • Remote operation/C3 – reliable, problem, unhumanised (kill at 10,000km) • Operator workload - multiple UAVs • Airspace and safety – UAVs operating in mixed airspace IET Seminar on Communicating with UAVs
Mixed air-sea-ground systems IET Seminar on Communicating with UAVs
C3 IET Seminar on Communicating with UAVs
Communications • GPS – location (but what about urban) • Inter-vehicle comms – information sharing, deconfliction, mission planning… • Back-to-base IET Seminar on Communicating with UAVs
Formation Flying • Routine for piloted aircraft IET Seminar on Communicating with UAVs
Issues • Different UAVs will have different capabilities - Global Hawk vs MAV • Different users have access to different techologies/legal frequencies • Makes very difficult to standardise IET Seminar on Communicating with UAVs
Multi-vehicle • Ground, sea and air IET Seminar on Communicating with UAVs
Dynamic Mission Planning • Autonomous navigation • Mission planning • Task allocation • Co-ordination IET Seminar on Communicating with UAVs
Search and destroy mission • Reasons for being dynamic IET Seminar on Communicating with UAVs
