Design Objectives Objective 1 –Measure of effectiveness Objective 2 –MOE Don’t need to list them all,but do list the primary objectives Could include the Objective Hierarchy on next chart Objective 1 –Measure of effectiveness Objective 2 –MOE Don’t need to list them all,but do list the primary objectives Could include the Objective Hierarchy on next chart

Objective Hierarchy To design the best possible space system O1. To maximize the performance O2. To minimize the cost O1.2 To maximize the lifetime O1.1 To minimize pointing error O2.2 To minimize operations cost O2.1 To minimize production cost M1.1 pointing error in radians M1.2 lifetime in years M2.1 production cost in $ O2.2.2 min facilities cost O2.2.1 min personnel cost M2.2.1 personnel cost in $ M2.2.2 facilities cost in $ O# Objectives M# Measures of Effectiveness

Design Approach Linkages between subsystems A block diagram illustrating the design flow would be useful here Linkages between subsystems A block diagram illustrating the design flow would be useful here Subsystem Analysis and Design Subsystem Analysis and Design Design variables Inputs from other subsystems Inputs from other subsystems Outputs to other subsystems Outputs to other subsystems iteration

Mission Overview The mission timeline looks something like this…. May take more than one slide to do this The mission timeline looks something like this…. May take more than one slide to do this
