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.
