  1. Issues and Challenges for Co-operative UAV Missions Chris Halliday and Tony Dodd

  2. Overview • Co-operative UAV missions • The Challenges • The Issues • Command, Control and Communications • Concluding remarks IET Seminar on Communicating with UAVs

  3. Large area: search and rescue IET Seminar on Communicating with UAVs

  4. Large area: search and rescue • Need to communicate with central command IET Seminar on Communicating with UAVs

  5. Combat Missions [3] IET Seminar on Communicating with UAVs

  6. Combat Missions • Search and destroy • Combat search and rescue IET Seminar on Communicating with UAVs

  7. Urban [1] IET Seminar on Communicating with UAVs

  8. Urban • Need to use existing communications • Results of US study • Is a communication infrastructure even in place? IET Seminar on Communicating with UAVs

  9. Agriculture, remote sensing, survey etc. [4] IET Seminar on Communicating with UAVs

  10. Agriculture, remote sensing, survey etc. • Must use licensed frequencies • Need for low cost solutions IET Seminar on Communicating with UAVs

  11. UAV Formation Flying/Refueling [2] [5] IET Seminar on Communicating with UAVs

  12. 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

  13. 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

  14. 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

  15. 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

  16. Mixed air-sea-ground systems IET Seminar on Communicating with UAVs

  17. C3 IET Seminar on Communicating with UAVs

  18. Communications • GPS – location (but what about urban) • Inter-vehicle comms – information sharing, deconfliction, mission planning… • Back-to-base IET Seminar on Communicating with UAVs

  19. Formation Flying • Routine for piloted aircraft IET Seminar on Communicating with UAVs

  20. 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

  21. Multi-vehicle • Ground, sea and air IET Seminar on Communicating with UAVs

  22. Dynamic Mission Planning • Autonomous navigation • Mission planning • Task allocation • Co-ordination IET Seminar on Communicating with UAVs

  23. Search and destroy mission • Reasons for being dynamic IET Seminar on Communicating with UAVs

  24. Work on this • GAs and other evolutionary algorithms… IET Seminar on Communicating with UAVs

  25. Concluding Remarks • Legislation • Certification IET Seminar on Communicating with UAVs
