Rancang Bangun Alat Pointing Antena VSAT Berbasis Mikrokontroler
Journal Title: Jurnal INFOTEL - Year 2016, Vol 8, Issue 1
Abstract
In this research, we discuss an application of microcontroller Atmega16 which is used as a pointing media for VSAT antenna. We use a linear change of potentiometer to choose azimuth and elevation angle. The potentiometer which connected with microcontoller are used as angle sensors to determine the azimuth and elevation angle. The ADC internal is used to convert an analog linear change of potentiometer into digital form. The main purpose of this research is to compare the electrical parameter of antenna as a result of manual and electronic pointing. Parameters used as reference for result of these pointing device are signal strength, signal quality, BER and C/N. The experimental result using two difference satellite target, we have shown the manual pointing better than the electronic pointing to get signal strength and quality, while the BER and C/N value are almost similar. Using the manual pointing and Satellite Telkom 1 as a target, the average value of electrical parameter of antenna are signal strength of 37%, signal quality of 56%, BER of 10-5, C/N of 8dB, while using the electronic pointing, the average value of electrical parameter of antenna are signal strength of 36%, signal quality of 55.4%, BER of 10-5, C/N of 7.9dB. Using the manual pointing and Satellite PALAPA D as a target, the average value of electrical parameter of antenna are signal strength of 43.5%, signal quality of 59.5%, BER of 10-5, C/N of 8.5 dB, while using the electronic pointing, the average value of electrical parameter of antenna are signal strength of 36%, signal quality of 40.9%, BER of 10-5, C/N of 8.5 dB.
