Command and Data Handling (C&DH)The C&DH system is responsible for monitoring the health and safety of the observatory. This includes collecting telemetry and housekeeping data, monitoring temperatures, sending out hardware commands. It will also store up to four terabytes of science data in its Science Data Recorder (SDR) for downlink to the ground when a ground station is in view.
