摘要：The paper addresses the application of the mathematical definition of a particle’s trajectory in maritime traffic. After the introductory definition of the concept of a particle’s trajectory, it goes on to provide a definition of the concept necessary for the understanding of the issues in question: the concept of the manoeuverability. Next, an example is given which defines the concept of a wave particle’s trajectory and the method of ship manoeuvring along a trajectory. Finally, there is a definition of the trajectory error and the method how to calculate it. There is also following the description of block scheme which depicts the way of steering a ship along a given trajectory with corresponding transfer functions. At the end, there is a conclusion.
