ESA: Be The First to Catch Signals From Student-built AAUSAT5 Cubesat
AAUSAT5 Cubesat

To celebrate the launch of the student-built AAUSAT5 CubeSat from the International Space Station into low Earth orbit, ESA’s Education office challenges the amateur radio community to listen out for the tiny satellite.
Be the first to send in your recorded signal from AAUSAT5 and you will receive a prize from ESA’s Education Office.

Launched on 19 August to the ISS, the Danish student CubeSat is now waiting for its deployment from the Japanese Kibo module’s airlock. Sometime in the week of 5 October, an astronaut will manipulate a robotic arm to lift AAUSAT5 from the airlock and place it in orbit.

Once launched from the International Space Station the CubeSat 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 us ( and Aalborg University (

The first correct email received will win the following prices:

– ESA/AAUSAT5 poster with signatures of the team members
– ESA Education goodie bag
– Scale 1:1 3D printed model of the AAUSAT 5 satellite

AAUSAT5 is the 5th CubeSat designed and built by the University of Aalborg, Denmark. It is the 2nd AAUSAT satellite tested under ESA’s supervision as part of the ESA Education Office’s Fly Your Satellite programme.

The technical objective of AAUSAT5 is to test an improved version of an Automatic Identification System (AIS), which aims to track and identify ships transiting away from coastal areas and those in remote areas.

If successful, a satellite-based AIS system could enable the establishment and use of safe new shipping lanes.

For more information please see the ESA AAUSAT5 website and the team site from the University of Aalborg.
