Abstract:	In this paper, we discuss several dynamical models of moving objects for kinematic GPS positioning by utilizing L1 and L2 carrier phase measurements. In precise kinematic GPS positioning, a suitable choice of the dynamical model for the moving object is important. Up to the present, many research activities have been focusing on determination of adequate dynamical model and their performance. The most popular model proposed for kinematic GPS positioning is that three coordinates of accelerations or velocities of moving objects are described by first order Markov processes. In this paper, these dynamical models are extended to be more suitable for the moving object such as the land vehicles. And then, new dynamical models and traditional models are compared in terms of the positioning accuracy and the ambiguity resolution. Finally, some comparative experiments using computer simulation are carried out and those results are shown.
