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.

FUNcube – the background
Given that:Cubesats are “cheap”Cubesats can be built quicklyCubesats 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?

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
RSGB-October 2011

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

FUNcube – telemetry reception
RSGB-October 2011
The “Ground Segment”- the FUNcube dongle
• An SDR radio designed and built by Howard Long G6LVB• The Pro version covers 61 -1700MHz• 96kHz bandwidth I/Q output – works with all freeware SDR
software & any OS• Possibilities for remote reception networks /parallel processing• Is creating a sensation!

FUNcube – Conclusions
• Educational project with benefits for every generation• Great example of volunteer teamwork• Is actually “pushing” legislation• Good publicity for amateur radio• Has spawned the development of the first amateur
VHF/UHF SDR radio • Has created a second launch opportunity for free• Is lots of FUN (and hard work)
