Implementation of Automatic Satellite Dish Positioning to Multiple Satellites

Abstract

Nowadays most of TV operators use satellites to provide a broadcast coverage to wide area. User within the covered area must have a satellite dish that is directly pointed to the satellite with clear line of sight conditions. The number of broadcast TV satellites is increased potentially in the past few years and users prefer to watch channels belong to different satellites. Receiving signals from multiple satellites using a single satellite dish antenna require moving it manually to receive the intended satellite signal which is too difficult because it take long time and much effort. The main objective of this project is to make it easier for moving from one satellite to anotherproviding smart solution for controlling the alignment of the satellite dish from one satellite to another. To achieve such goal an android application running on an android device is responsible for computing the required antenna look angles and then it wirelessly communicates with anARDUINO using Bluetoothto move stepper motors to these computed angles, as a result the user will receive strong signal. Simulation results demonstrated an ARDUINO is able to drive stepper motors to the intended positions. System was implemented using two stepper motors, ARDUINO, Bluetooth module and CD. The behavior of the system is evaluated by means of angles of rotation by using a Serial monitor
