When
April 9, 2026, 7:37 – 7:46 a.m.
Where
CatSat will activate its X-Band system and transmit a DVBS-2 modulated data stream centered at 10.47 GHz. The modulation will be Quadrature Phase Shift-Key (QPSK) with a 1/4 forward error correction fraction. The symbol rate will be 4M baud.
The event is scheduled as a pass over a surface point located at Maidenhead grid DM42mg. Transmission will begin when the spacecraft ascends above 5 degrees and will end when the spacecraft crosses below 5 degrees.
The spacecraft will rotate to track a ground station on the surface.
