Techno-Economic of the Ka-Band HTS to Minimize Broadband Services Gap for Indonesian Government

Abstract

Satellite technology has a vital role in delivering big archipelagic country communication services, including Indonesia, for many years. It is not surprising that there are many satellites above Indonesia regions, either foreign or Indonesian satellites. From those satellites, the majority of them still use conventional satellites in C or Ku Bands. As time goes by, these C and Ku Band’s use is very limited in generating channel capacity to extend the capacity for responding to the massively increasing number of capacity demand in the broadband era. This paper discussed the potential use of the next generation high throughput satellite (HTS) in the Ka-Band frequency spectrum using a techno-economic analysis perspective. The technical result shows that it potentially fulfill 114.67 – 1,031.51 Gbps using 244 beams (61 Frequency Reuse Factor). Then, the economic result obtained the NPV of Rp13,168,414,276,316.20 (positive value > 0), the IRR of 15% (more than WACC), the profitability Index of 2.94 (greater than 1), and the HTS implementation can reach a payback period of around nine years two months.
