Nusantara Satu was built by Space Systems Loral (SSL) and was launched on 22 February 2019 on a Falcon 9 Block 5 launch vehicle along with the satellite Beresheet (2019-009B) Moon lander by SpaceIL and Israel Aerospace Industries (IAI) and the microsat S5 (2019-009D) by the U.S. Air Force Research Laboratory (AFRL).
Nusantara Satu is a communications satellite developed and designed by SSL for PT Pasifik Satelit Nusantara (PSN), the first private company in the telecommunications and information services sector in Indonesia.[3][5][7] The project's cost is US$230 million.[5][7]
The massive satellite features solar-electric ion thrusters[2] but also employs conventional chemical propellant for stationkeeping while in orbit.[2]
The Nusantara Satu satellite carries 26 C-band, 12 extended C-band transponders and 8 Ku-band transponders. The satellite offers a total bandwidth of 15 gigabits per second.[3] Its expected service time is a minimum of 15 years.[1] It will provide communications links to rural parts of Indonesia, allowing PSN to expand broadband internet services into these regions.[8]
