Models of movement of indicators of the course and glidepath with pendular system of stabilization of optical axes

The objects of research in this article are the course displays and glidepath indicators (CD/GI) assigned for visual landing of helicopters on naval vessels boards during the day and night, in simple and adverse weather conditions. The mathematical models of CD/GI for regular and irregular ship motion are considered in this article. The comparison of these models shows the good coincidence between the results obtained using the each model.
