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.

CASAA-Sat launch 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,MarcusOn 26.12.24 08:53,
