A-5. Mission Planning Control Flow Diagram

Figure A-6 depicts the time ordering of processes in Mission Planning. Certain processes require vehicle-specific configuration information. This data is input into databases and knowledge bases at system configuration time, when the configuration of the TT&C system for a particular satellite or satellite family is defined.

During the normal daily planning cycle, the processes are ordered based on possible needs of subsequent processes. Not all processes must be performed in each cycle. For example, if no attitude maneuver planning is necessary, none will be performed. Additional variations on this processing sequence may occur during launch and early orbit operations.

Attitude maneuver planning is accomplished first because an orbit maneuver may require that an attitude maneuver be planned prior to the orbit maneuver. Since, orbit maneuver planning must request the attitude maneuver planning activity, the process may be more complicated than depicted in the CFD.

Once all maneuvers are planned, maneuver requirements and any other SOH requirements are consolidated for the Schedule Resources process. The scheduling process itself is iterative, involving submission of requests to the RMS and possible negotiation regarding those requests.

The final process is the generation of pass plans for inclusion in the final Timeline.
