The Mars surveyor operations project command generation process
The methods employed by the Mars surveyor operations project (MSOP) flight team to accelerate the command generation process are described. The approach adopted was to develop a ground system which could simultaneously support as many as three spacecraft in various phases of flight and two in development. The uplink element of the MSOP is discussed, including the control of the science instruments and the spacecraft bus using real-time commands as well as time-tagged stored sequences. The non-interactive payload command process, the express command process, the coordinated command process and the stored sequence process are described. The automation of these processes resulted in flight operations cost savings while maintaining a minimum of risk.
