Operational Database

The operational database contains all relevant telemetry and telecommand information.

For detailed insights, please refer to the attached file PoCat TM_TC DATABASE.xlsx. This Excel document contains a list of all the telemetry data and telecommands that allow the control of the satellite and the successful execution of the mission.
