FUNcube (AO-73)

FUNcube ModelAMSAT-UK is working on a new amateur satellite project – The FUNcube Project– that features a 435 to 145 MHz Linear Transponder for SSB/CW operation. FUNcube-1 is a complete educational single CubeSat project with the goal of enthusing and educating young people about radio, space, physics and electronics.


The primary and secondary mission objectives are summarized below:

Provide an in-orbit tool for science education and outreach, by means of the following:

  • Perform a materials science experiment in space.
  • Provide for telemetry which is receivable by un-trained teachers and schoolchildren using a handheld receiver.
  • Provide a message service similar to Text/Twitter messages. These messages to be uploadable by designated control stations, and to be transmitted. These messages to be known as “Fitter” messages.

Provide a linear transponder which can be used by radio amateurs to make 2-way radio contacts using a modest equipment setup.
