  1. HAP Network Concept

  2. SkyNet - JAPAN

  3. Milestones for Development of HAPs (Designed by NAL, Japan) 2006~ 2002~2003 Commercial Flights Technology Demonstrator Flight 2003~2004 Ground-to-Stratosphere Test Flight (45-m class, non-powered, Payload 40kg) Low-Altitude Station-Keeping Flight (65-m class, powered, Payload 250kg) (150-m class, powered, Payload~500kg?) (250-m class, Powered) Total system test, Telecom and observation mission Test on materials, Thermal control, Environmental observation ~20km ~15km Control, Operation, Telecom mission ~4km See www2.crl.go.jp/mt/b181/research/spf/index-e.html

  4. The CAPANINA Consortium • €5.6M total, €3.1M EU Contribution • 64 people involved • Balanced research, development and exploitation activities • 1 Overseas collaborator National Institute of Information and Communications Technology of Japan

  5. SkyStation - USA See www.skystation.com

  6. ATG StratSat - UK 200 m class airship. Communications Payload 1000-2000 kg See www.airship.com

  7. StratSat Malaysia (UK Consortium)

  8. StratSat Malaysia

  9. AeroVironment craft • Unmanned • Wing span 247 ft • Achieved height of 96863ft Aug 2001 • Range of craft • NASA funded • (now spin off company called Skytower Inc to handle comms links) See www.aerovironment.com,www.skytowerglobal.com

  10. A Complementary or Disruptive Technology? Complementary - augment existing systems - niche markets - small number of users Time Disruptive - well developed technology - large number of users - replace terrestrial/satellite services - mobile, B-FWA

  11. Lenticular airship Satellite backhaul for areas with no infrastructure B-FWA 150km diameter footprint Mobile ‘3G’ up to 1000km diameter footprint?

  12. Backhaul via satellite for remote areas Local Backhaul to Hub for less remote areas Fibre Network Fibre Network HAP Architecture Broadband Services 60km

  13. HAP Supersonic Aircraft Structure of the Atmosphere IONOSPHERE THERMOSPHERE 100 km 80 km MESOSPHERE 50 km STRATOSPHERE 10 km TROPOSPHERE 0 km

  14. Using Site Diversity to Overcome Rain Attenuation Site Diversity on the backhaul link Backhaul Ground Stations

  15. CONFIDENCE INVESTMENT DEMONSTRATION DEVELOPMENT So, will HAPs really Happen?

  16. Either airships or planes Situated typically 17-22km above the Earth HAPs - What are they ?

  17. 5º elevation Coverage from a HAP • Potentially very large coverage. • E.g. - 1 HAP over London @ 20 km altitude: line of sight:

  18. MedNet: Planned network of HAPs - each covering a city region
