large area search and rescue1
Large area: search and rescue
  • Need to communicate with central command

Combat Missions
  • Search and destroy
  • Combat search and rescue

urban1
Urban
  • Need to use existing communications
  • Results of US study
  • Is a communication infrastructure even in place?

  • Must use licensed frequencies
  • Need for low cost solutions

uav refueling
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
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
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
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
Mixed air-sea-ground systems

C3

IET Seminar on Communicating with UAVs

communications
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
Formation Flying
  • Routine for piloted aircraft

IET Seminar on Communicating with UAVs

issues
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
Multi-vehicle
  • Ground, sea and air

IET Seminar on Communicating with UAVs

dynamic mission planning
Dynamic Mission Planning
  • Autonomous navigation
  • Mission planning
  • Task allocation
  • Co-ordination

IET Seminar on Communicating with UAVs

search and destroy mission
Search and destroy mission
  • Reasons for being dynamic

IET Seminar on Communicating with UAVs

work on this
Work on this
  • GAs and other evolutionary algorithms…

concluding remarks
Concluding Remarks
  • Legislation
  • Certification
