DIRECTION CONTROLLING OF DISH ANTENNA

Presented By: Hajira Sadia 07H81A0405

INTRODUCTIONINTRODUCTION

• The combination of software and hardware and some The combination of software and hardware and some mechanical parts require to built a product is called as mechanical parts require to built a product is called as ‘EMBEDDED’ system.‘EMBEDDED’ system. • Generally in previous days we don’t have dish antennas and all Generally in previous days we don’t have dish antennas and all the star connections are connected by cables and even today 80% the star connections are connected by cables and even today 80% of the people are using the cables when compared to the modern of the people are using the cables when compared to the modern connection of DTH.connection of DTH.

• For the distributors it is difficult to adjust the direction of the For the distributors it is difficult to adjust the direction of the antenna in minute angles by manually. That’s why we are antenna in minute angles by manually. That’s why we are designing an automated system for the direction controlling of designing an automated system for the direction controlling of the dish antenna.the dish antenna.
