The study of dynamics can be divided into two parts: kinematics, which treats only geometrical aspects of motion, and kinetics, which is the analysis of the forces causing the motion. For marine craft moving in six degrees of freedom, six independent coordinates are necessary to determine the position and orientation. These are: surge, sway, heave, roll, pitch and yaw. Geographical reference frames are usually chosen as tangent planes on the surface of the Earth. Wide‐area or terrestrial guidance and navigation implies that the position should be related to the Earth center instead of a local frame on the Earth's surface. The chapter describes the kinematic transformation between Earth‐centered Earth‐fixed and North–East–Down parametrized in terms of longitude, latitude and height. The relationship between the angular variables course, heading and sideslip is important for maneuvering of a marine craft in the horizontal plane.
