Design and Modeling of the Properties of the Servomechanism for a Mobile Free Space Optical Link

Abstract

The paper deals with the design of a tracking system determined for mobile free space optical link communication system. The paper also contains description of two-step method of the optical-axes pointing process, description of the basic properties of servomechanisms and results of the simple simulation of the tracking-system function model. The entire model consists of four partial models, i.e. of model of trajectory, model of uneven road surface, model of vehicle and model of horizontal and vertical servos. Results of these simulations will be used to give precision to the construction design of the mobile free space optical link station and its servomechanisms.
