The FUNcube Project - Educational Outreach with Amateur Radio Transponder

The FUNcube Project aims to provide educational outreach in STEM subjects through a satellite with an amateur radio transponder. The project also includes a ground segment with a FUNcube dongle for receiving and processing data.

  1. The FUNcube Project – the background Given that: Cubesats are “cheap” Cubesats can be built quickly Cubesats 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? 22/06/10 1

  2. The 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 22/06/10 2

  3. Amateur 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 22/06/10 3

  4. The “Ground Segment”- the FUNcube dongle • 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

  5. The “Ground Segment”- the FUNcube dongle

  6. FUNcube-1 Hardware “CCT” Command Control + Telemetry Board • Xilinx CPLD command decoder • Freescale CPU for telemetry generation • 2 x I2C Bus • 3.3V supply • Average power consumption 15mW • Peak power 33mW

  10. 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
