In the design and performance evaluation of a navigation system, the orbit dynamics model, attitude kinematics model, and environment model should be established. This chapter first addresses orbital perturbation model, establishes orbit dynamic equations, and then elaborates on four typical parametric forms for attitude description, the conversion relations between attitude parameters, and the attitude kinematics model corresponding to each parameter. Finally, Mars and asteroids are taken as examples to introduce the modeling methods of celestial environment, including celestial body shape modeling and gravitational field modeling.
