Abstract The time-honoured method that operations engineers use to check that the mission (space and ground control) is performing as expected is by implementing checks in the operational databases. These are typically checks to see if spacecraft parameter values are between predefined limits or in predefined states. There are also command verification checks contained in the procedures or integrated into the control system. These are checks to see if spacecraft parameter values are between predefined limits or in predefined states after a command has been sent. Two important trends to note are that the number of spacecraft telemetry parameters and telecommands keeps increasing with time and the manpower for operating the ground systems keeps being reduced. This means that the present systems, involving engineers defining these checks individually and manually in operational databases/procedures, are by nature incomplete. What is needed in the future is a system that can derive checks automatically from historical data. Once such an automatic system exists, it can be expanded to check many more spacecraft telemetry parameters, verify more commands and check more procedure steps with very little effort on the ground side. It can also be used to check much more useful features in the telemetry than the present limit and status checks employed.
