ESA / Education / CubeSats - Fly Your Satellite!

It is time to start listening to space. To celebrate the launch of the three Fly Your Satellite! student-built CubeSats into low Earth orbit, ESA’s Education office challenges the amateur radio community to listen out for the tiny satellites. 

The first three radio amateurs to send a recorded signal from either AAUSAT4, E-st@r-II or OUFTI-1 will receive a prize from ESA's Education Office.

The satellites have been launched onboard the Soyuz VS-14 flight from the European Spaceport in Kourou, French Guiana on 25 April at 23:02 CEST. Together with CNES’ Microscope scientific satellite, they were auxiliary payloads in the launch of ESA’s Earth observation satellite Sentinel-1B, the main passenger on this flight.

Soon after being deployed into their final orbit, the CubeSats will begin transmitting signals to Earth that can be picked up by anyone with common amateur radio equipment. ESA challenges anyone to record the signal and send it to, and to the CubeSat team.

For each CubeSat, the first email received for which the signal is confirmed to belong to the CubeSat will be awarded with the following prizes:

  • ESA Fly Your Satellite! poster
  • ESA Education goodie bag
  • Scale 1:1 3D printed model of a CubeSat
