Design & Development of Periscope Coarse Pointing Gimbal Mechanism

This paper describes design and development of a Coarse Pointing Assembly for optical communications. The design involves a dual-axis periscope gimbal-based mechanism. It comprises of two sub-assemblies i.e. Azimuth and Elevation assembly responsible for compensating the relative motion of satellite and earth respectively. Kinematic analysis of periscope gimbal is carried out using MSC ADAMS multibody simulations. The results obtain reflect on structural feasibility and torque calculations and values. Static behavior of the design is further analyzed using CREO parametric.
