  1. FUNcube Satellite 22/06/10 1 Shefford - May 2011

  2. Introduction • Background information about AMSAT and AMSAT-UK • Brief history of “OSCAR” satellites • Info on today's operational spacecraft • Background of FUNcube • FUNcube – what it will do • Expected timelines • The follow on spacecraft • Some conclusions 22/06/10 2 Shefford - May 2011

  3. AMSAT–UK 500 individual members –most are active radio amateurs. One of more than 20 such groups worldwide. In Europe, AMSAT groups exist in France, Germany, Italy, Spain, Portugal, Denmark , Sweden, and the UK.

  4. OSCAR Satellites Oldest - Oscar 1 - launched 1961

  5. OSCAR Satellites • Largest – Oscar 40 – launched 2000 • 450kg to HEO on an Ariane 5

  6. OSCAR Satellites Oldest still operational - Oscar 7 - launched 1974

  7. OSCAR Satellites Latest –HW-1 – launched Dec 2009 - Oscar 68

  8. OSCAR Satellites Created by groups in – US, Japan, UK, Russia, China, France, Germany, Australia, Argentina, Brazil, Canada, Korea, Israel, Italy, Portugal, Saudi Arabia, Malaysia, Mexico, Thailand, India, Netherlands, South Africa

  9. AMSAT-UK provided an S band transmitter/transponder in June 2004 and it was launched in October 2005 – Oscar 53

  10. In the beginning - AO51 We offered a 3 watt S band PA in April 2004 It was launched in June 2004

  11. Columbus L/S Band Antennas

  12. The Amateur Satellite Service ITU regulated frequency bands: HF @ 7, 14, 21 & 28MHz VHF @ 145MHz UHF @ 435, 1260* & 2400MHz Microwave @ 3.4GHz*, 5.6GHz*, 5.8GHz*, 10GHz, 24GHz + * - with some limitations .

  13. .

  14. Cubesats Standard - less than I.3 kg 100x100x100mm Double and triples also possible Standard deployment mechanisms “PODS” .

  15. PSLV launcher . CubeSat deployers

  16. Current cubesat statistics 40 launched already 200+ being developed Created by groups in: US, India, Netherlands, France, Switzerland, Italy, Germany, Denmark, Norway, Austria, Spain, Portugal Poland, Estonia, Japan, Turkey, Mexico etc etc….. .

  17. FUNcube – the background • Given that: • Cubesats are “cheap” • Cubesats can be built quickly • Cubesats should be “simple” • So: • Could we create an educational outreach mission? • Could it also have a amateur transponder? • Could we create a team of volunteers with the skills/passion? • Could we develop the actual educational outreach? • Could we fund it? 22/06/10 19 Shefford - May 2011

  18. FUNcube – primary objective • EDUCATIONAL OUTREACH • STEM subjects • Radio – practical understanding of communication • Electronics – how radios work • Physics – Data from 40+ telemetry channels • Orbital mechanics - Doppler • Materials science payload • -Demonstrate loss of heat energy by radiation from two materials with differing surface finishes • “Fitter Message” • - Short greetings messages 22/06/10 20 Shefford - May 2011

  19. FUNcube Satellite • 1-Unit CubeSat • COTS CubeSat structure, EPS, Solar panels, PMAS and antennas • Bespoke CCT (Command, Control & Telemetry) Board • Bespoke RF and HPA boards • VHF telemetry downlink– 1k2 BPSK with FEC (Forward Error Correction) • Materials science experiment • Mode UV linear transponder (20kHz, 1W PEP) • Designed for SSO at around 600km (with a >5 year mission life!) • AMSAT-UK’s first spacecraft 22/06/10 21 MKARS Presentation Feb 2011
