Abstract
Coordinate time series are, by definition, trajectories, so the kinematic models that geodesists and geophysicists use to describe these time series are trajectory models. We describe various classes of trajectory models, and present a dozen case studies that illustrate the use of these models and also illuminate the diversity of ways in which the Earth moves and deforms. We distinguish between the deterministic approach to trajectory modelling, which emphasizes the physical meaning of the various components of the trajectory, and a more automatic, autonomous and heuristic approach to finding and fitting a trajectory model.
