CAS-4A NORAD Cat ID 42761 Decayed from orbit on or about 9 October 2025
CAS-4A and CAS-4B have been decommissioned
At present, the remote sensing payloads on CAS-4A and CAS-4B satellites have been decommissioned, and the on-orbit attitude management of these two satellites on the ground has ended. As the attitude errors of the satellites gradually increase, the solar array panels will not be well aligned with the sun, and the satellite’s power supply will gradually deteriorate, resulting in the amateur radio payload not being able to work continuously without interruption.
CAS-4A over middle east
Still all the same after a year, beaming packets left right and center, over a year >80 OBC resets. Maybe also a bit more uplink activity seen in RX AGC

CAS-4B test mode
Thought something wrong with CAS-4B – seems it went into test mode it is still transmitting but not decoding telemetry
