The FUNcube Project – the backgroundThe FUNcube Project – the background
Given that:Cubesats are “cheap”Cubesats can be built quicklyCubesats should be “simple”
So in 2009 we asked ourselves: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?

The FUNcube Project – primary objectiveThe FUNcube Project – 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
The spacecraft transmits 1k2 BPSK telemetry on 145.935MHz

Amateur radio operationsAmateur radio operations
• During the local night (eclipse) the sub-system switches into amateur radio mode:
• Receives on UHF (435.150 – 435.130 MHz) and transmits on VHF (145.950 – 145.970 MHz)
• The amateur radio transponder can be used to demonstrate radio communications to schoolchildren and students of all ages
• Students are able to hear amateur voice signals when the satellite passes overhead

The “Ground Segment”- the FUNcube The “Ground Segment”- the FUNcube dongledongle
• An SDR radio designed and built by Howard Long G6LVB• The Pro+ version covers 150 KHz -1.9 GHz• 192kHz bandwidth I/Q output – works with all freeware SDR
software & any OS• Possibilities for remote reception networks /parallel processing

FUNcube-1 Telemetry FUNcube-1 Telemetry
1200 BPS BPSK with forward error correction with 54 Telemetry channels
Telemetry is sent in 24 x 5second frames over 2 minute period
“Real time” every 5 secs, “Whole orbit” data sampled every 60 secs stored for 104 minutes and “High Res” data sampled at 1 second intervals for 60 seconds
Text messages- 9 x 200 character greetings messages & 27 additional messages stored in memory
Very distinctive sound to enable easy identification 4.3 seconds of data + 0.7 seconds of BPSK mark tone
