Abstract
Satellite communication system is one of the communication methods which is very important and widely used now a days. Through this communication system, we are able to communicate with anyone, any time in any place around the world. Information is freely transmitted along the air space without utilizing any cable or wire. Thus, this communication method became really important for human in need in order to communicate with more convenience and faster. However, this system causes the transmitted signal to be easy to get expose towards any disturbance. One of the factors that causes this disturbance is the unpredictable of weather condition such as rain, humidity, air temperature and wind speed that are liable to change. For that reason, this project has been executed to analyze the effectiveness of these atmospheric factors in attenuating the satellite signal. By using Minitab software, correlation analysis is done towards rainfall, humidity, air temperature and wind speed and satellite signal (beacon signal) data in order to determine the strength of relationship between these factors upon the satellite signal. Through this analysis, rainfall and wind speed seems to be more dominant in attenuating the satellite signal rather than other atmospheric factors. Then, regression analysis is done in purpose to model the satellite signal prediction system which is able to estimate an exact satellite signal in mutable weather condition. This system is created in order to amplify back the attenuated signal to reach the satellite signal receiver, so that, the disturbance in satellite communication system is prevented or at least is reduced. However, the model which has been created only explained 63% of the total variation in Beacon signal. This is happened because the data used is uncompleted. Therefore, some improvement should be done to enhance the accuracy and effectiveness of this system in the future. As conclusion, this research has achieved the objectives of the project, and hopefully it will give some benefits to future research.
