Abstract

Abstract:

Radio and optical telescope are used for studying radiation emitted by extra terrestrial sources. The radio telescope is astronomical equipment consisting of radio receivers and antenna system used to detect radio frequency emission emitted by extraterrestrial sources. The optical telescope is used for studying and analyzing radiation from the visible portion of the electromagnetic spectrum. The performances of space observational 
equipment’s are limited by various factors; 1) The accuracy of the reflecting surface that may depend on the ideal shape because of manufacturing 
irregularities. 2) The effect of wind load 3) Thermal deformation that causes differential expansion and contraction 4) Deflection due to changes in 
gravitational forces as the antenna is pointed to different parts of the sky.  Human and natural phenomenon like wind load heavy rainfall storm and 
manual shift (intentional or unintentional) can cause mechanical displacement of the observational equipment thereby causing many receivers move from their designated position. This affects signal reception needed for frontline space research. We propose a dish or telescope positioning control system capable of monitoring and controlling any misalignment of dish orientation through azimuth and elevation. We incorporate motors that can receive command via micro controller connected to the system. This work entails the demonstrative model and the idea is to deliver a system which will control the movement of the observational telescope in all direction in order to overcome the difficulty experienced when adjusting the system manually.
