Project Summary

With the increasing popularity of Television satellite reception systems, there has been a tendency to apply the available technology in connection with recreational vehicles. Such vehicles also have achieved considerable popularity and accordingly, a need has developed for practical, inexpensive and readily adaptable systems for dish antenna installation on recreational vehicles so that the vacationer/traveller can enjoy satellite-transmitted television programs.Satellite television is a miracle of modern technology, delivering clear, crisp picture and sound from satellites thousands of miles away, captured by a relatively small satellite dish.

Over the past decade, TVRO antennas have grown substantially in popularity and are typically found in geographical areas where cable or broadcast television is not prevalent. The advent of such commercially available programming from these satellites has found growing popularity among recreational vehicle (RV) users who would like to tap into this programming during their trips around the country in recreational vehicles. Initial satellite TVRO systems for recreational vehicles were simply comprised of a small TVRO dish antenna placed on the ground near the RV which was then manually adjusted with great care and time to locate and tune into an individual satellite. The tuning process would be repeated for tuning into another satellite. This approach was somewhat effective but resulted in considerable set-up time by the consumer and usually resulted in low quality signals in the television set.

We are designing two-axis control system for a receiving antenna (BSS) over a moving platform. We will calculate angle of elevation and azimuth angle from latitude and longitude values obtained from GPS. The ATmega328p will compare these angles with current angles of the dish antenna, taken using HMC5883 and MPU6050 placed along the dish antenna. If the angles are not aligned, then the controller will adjust current position of our dish antenna by moving it through stepper motors connected. Once the respective angles provided by user are in accordance with dish angles, we will receive proper output from our dish receiver. In this way, our dish antenna will automatically adjust to provide dish channels on our moving vehicles.

Project Objectives

This project requires a hand-on experience of the following subjects:

• Electronics
• Microprocessor Systems
• Programming
• Structure Designing
• Control Systems

So, through this project we wish to integrate our theoretical knowledge with practical experience to gain further insight and redefine our skills in all the fields mentioned above.

One of the biggest applications of this project is in Recreational vehicles (RVs).

Project Implementation Method

We are designing a two-axis control system for a receiving antenna (BSS) over a moving platform. We will get the Latitude and longitude from GPS module. After that we calculate desired azimuthal and elevation angle then we will compare these angles with current angles of the dish antenna, taken using MPU6050 placed along the dish antenna. If the angles are not aligned, then the controller will adjust current position of our dish antenna by moving it through stepper motors connected. Once the respective angles provided by user are in accordance with dish angles, we will receive proper output from our dish receiver. In this way, our dish antenna will automatically adjust to provide dish channels on our moving vehicles.

Benefits of the Project

With the increasing popularity of Television satellite reception systems, there has been a tendency to apply the available technology in connection with recreational vehicles. Such vehicles also have achieved considerable popularity and accordingly, a need has developed for practical, inexpensive and readily adaptable systems for dish antenna installation on recreational vehicles so that the vacationer/traveller can enjoy satellite-transmitted television programs.

Technical Details of Final Deliverable

Our project involves Neo-6m that provides latitude and longitude to ATmega328p to calculate angles (elevation and azimuth). These are the desired angles of elevation and azimuth of the dish. Now to get current angle of elevation and azimuth, we used gyroscope MPU 6050. Arduino nanouse calculated values to configures MPU 6050 gyroscope, calculate PID values and control actuators. In this way, Arduino nano controls the stepper motors. Stepper motors will control the dish and move the dish to the desired angle. As a result, the LNB receiver will receive signals and send it to the TV stationto provide dish channels on our moving vehicles.
