From ESA:
Calling all radio amateurs! ESA is challenging anyone with amateur radio equipment to catch the first signals from OPS-SAT, ESA’s brand new space software laboratory.
On 17 December, OPS-SAT will be launched into low-Earth orbit on a Soyuz rocket from Kourou, French Guiana, together with ESA’s Cheops exoplanet-tracker.
Once launched, the satellite will deploy its solar panels and ultra-high frequency antenna, and then start to send signals back home.
Could you be the first on Earth to catch them? ESA’s mission control team in Darmstadt are asking for your help to find the fledgling CubeSat.
