I have developed a controller for spacecraft rendezvous using low thrust propulsion system. In the controller, it appears that we need to have a knowledge of jerk and snap (first and second derivative of acceleration) of the spacecraft, as inputs. However, we know that jerk, and more so, snap are hardly measurable, and differentiating acceleration to get these values would be full of noise. How can you handle such scenarios?
