A systems engineering approach to Guidance, Navigation, and Control (GN&C) design is essential to achieve performance objectives, minimize risk, and to meet program schedule and cost. The GN&C design is strongly coupled with all other spacecraft subsystems and subject to mission requirements and constraints. For example, environmental factors such as thermal control affect attitude sensor performance and alignment, calibration maneuvers are limited by pointing and mission constraints, structural modes and propellant slosh can cause image motion (such as smear, and jitter) that degrades optical payload performance, and control-structure interaction can cause instability of the pointing control system.
