Oh, my condolences! Still looking forward to hearing more from the university
team!
All the best,
Marcus

Hi Marcus,
Unfortunatly, the rocket encountered a problem and the flight terminaison system had to be
activated at about an altitude of 150km.
As a consequence, CASAA-SAT will never transmit. We don't know at the moment if the lab
will rebuild it for another launch.
Best regards,
Fabien.

Hi Fabien,
darn! Missed the launch! This is exciting news! Please keep us updated! Do you
have a GNU
Radio Flowgraph with which interested readers could monitor the satellite? TLEs?
Best regards,
Marcus
