Study of Nusantara Satu Satellite parameter evaluation for broadband application in Indonesia

Abstract

This study aims to evaluate the performance of Satellite Nusantara Satu which has just been launched. Nusantara Satu Satellite is a broadband satellite that uses High Throughput Satellite (HTS) technology and uses Ku-band transponders to cover all regions in Indonesia. However, the use of Ku-band frequencies in Indonesia, which is located at a tropical region, must be evaluated because of the characteristics of the Ku-band frequency are very vulnerable to rain attenuation. In general, a broadband service requires link availability of 99.9% with a minimum speed of 100 Mbps. Our simulation results show that in the western part of Indonesia, to reach 100 Mbps with 99.9% link availability, the EIRP of the earth station VSAT is minimum at 79 dBW. In the central part of Indonesia, to reach speeds of 100 Mbps with 99.9% link availability, the EIRP of the earth station VSAT is minimum at 83 dBW. And in the eastern part of Indonesia, to reach speeds of 100 Mbps with 99.9% link availability, the EIRP of the earth station VSAT is minimum at 84 dBW.
