Abstract

PADA SATELIT IRIDIUM YANG BEROPERASI PADA FREKUENSI UPLINK 1650 MHz. Rori Arkan Ibadillah Kartiko ArdimWidodo Sotyohadi roriarkanibadillah@gmail.com Abstrak Satelitiridium merupakan satelit dengan orbit rendah dan merupakan salah satu type satelit LOW (Low Earth Orbital). Konstelasi satelit iridium terdiri dari 66 satelit aktif di orbitnya, yang menyediakan pelayanan suara dan data ke telepon satelit, pager dan transceiver terintegrasi di seluruh permukaan bumi. Rugi-rugi lintasan (dB) didefinisikan sebagai perbedaan antara daya yang di transmisikan dengan daya yang diterima. Yang disebabkan oleh karakteristik media perantara serta adanya pengaruh lingkuangan cuaca,dll. Penelitian untuk mengetahui rugi-rugi lintasan pada satelit iridium dengan Uplink 1650 MHz pada kondisi lingkungan dan cuaca yang ada diperlukan untuk mengetahui feasibility system komuikasi tersebut. Hasil pengukuran daya terima melalui antenna penerima yang dihubungkan dengan sebuah spectrum analyzer dibandingkan dengan hasil perhitungan teoritis daya terima dalam dB. Dari kedua hasil tersebut dilakukan Analisa dan evaluasi terhadap perbedaan yang ada. Dalam penelitian dikaji terhadap tiga buah satelit iridium yaitu satelit iridium 32,45,dan 60 serta di kaji juga terhadap kondisi cuaca cerah dan mendung. Lokasi penelitian ini dilakukan di Gedung workshop Teknik elektro ITN malang kampus 2. Hasil Analisa menunjukkan semakin besar jarak maka daya terima makin kecil, yang berarti juga rugi-rugi lintasan semakin besar. Terdapat perbedaan hasil pengukuran dengan teoritis 2 – 4 dB. yang disebabkan antara lain factor cuaca, redaman atmosfer,serta gain dari gain antenna penerima. Sedangkan untuk kondisi cuaca cerah dan mendung, daya terima satelit iridium tidak begitu berbeda. Kata kunci:satelit iridium, rugi-rugi lintasa, feasibility system,daya terima. ANALISIS RUGI-RUGI LINTASAN PADA SATELIT IRIDIUM YANG BEROPERASI PADA FREKUENSI UPLINK 1650 MHz. Rori Arkan Ibadillah Kartiko ArdimWidodo Sotyohadi roriarkanibadillah@gmail.com Abstract Iridium satellite is a satellite with low orbit and is one type of satellite LOW (Low Earth Orbital). The iridium satellite constellation consists of 66 active satellites in its orbit, which provide voice and data services to satellite phones, pagers and integrated transceivers across the entire surface of the earth. Track losses (dB) are defined as the difference between the transmitted power and the received power. Which is caused by the characteristics of the intermediary media and the influence of the weather environment, etc. Research to determine the path losses on iridium satellites with Uplink 1650 MHz on existing weather and environmental conditions is needed to determine the communication feasibility system. The measurement results of receiving power through the receiving antenna connected to a spectrum analyzer compared to the results of theoretical calculations of acceptability in dB. From the two results, an analysis and evaluation of the differences was carried out. In the study studied three iridium satellites, i.e. iridium 32.45 and 60 satellites and also studied the conditions of sunny and cloudy weather. The location of this research was carried out at the Electrical Engineering Workshop in ITN campus 2. The analysis results showed that the greater the distance, the smaller the receiving power, which meant the greater the loss of the track. There are differences in the measurement results with theoretical 2-4 dB. caused by weather factors, atmospheric attenuation, and gain from the receiver antenna gain. As for sunny and cloudy weather conditions, the reception of iridium satellites is not so different. Keywords: iridium satellite, track loss, feasibility system, receiving power.
