DATO Problem ModellingDescent Trajectory (1/3)Basic Assumptions1. Rigid body;2. Two-dimensional motion.MotionThe motion is considered lying in theXLYL plane and the position of thevehicle is characterised by sphericalcoordinates (R, !), with !=90 [deg].The vehicle’s rotation is representedby the pitch angle "="(t).
