High Throughput Satellite using Ka-Band for Government Multifunctional Services in Indonesia: Study of Link Budget and Capacity Analysis

Satellite infrastructure has a vital role in delivering communication services throughout Indonesia as one of the biggest archipelagic countries in the world. The high throughput satellite (HTS) can be the best choice considering the uneven distribution of terrestrial infrastructure networks, especially in the corners and isolated areas of Indonesia. In this paper, a study is conducted related to link budget and capacity analysis on the high throughput satellite using the proposed Ka-band frequency plan. The purpose of this study is to find out how far the link capability and capacity can be provided by HTS if it is operating in the proposed Ka-band frequency plan associated with Indonesia's environmental conditions. The result of this study on link budget analysis shows that using its Ka-Band frequency plan as the proposed assigned frequency is suitable and feasible to be implemented in the near future of the HTS system for government multifunctional services over Indonesia. It is indicated by the positive value of C/N obtained from link budget analysis for each link of each scenario in this research. Besides that, the estimation for capacity analysis of communication that is able to be provided by its HTS is enormous enough to handle the data services needs over Indonesia, which is 38.41 – 93.54 Gbps depends on environment condition.
