'Satria' Advancing Indonesian Archipelago Telecommunications into the Future
June 19, 2023: SpaceX successfully launched the Indonesian satellite SATRIA (SiateliT Republic IndonesiaA) aboard the Falcon 9 v1.2 FT Block 3 rocket on Sunday, June 18, 2023. The rocket took off from Space Launch Complex 40 (SLC-40) at 22:21 UTC from Cape Canaveral Space Force Station in Florida. The first stage B1067.12 of the Falcon 9 rocket landed on the drone ship A Shortfall of Gravitas, situated 683km downrange from the Cape, in the Atlantic Ocean. The head fairing shells were planned to be recovered at sea by the support ship Doug.
SATRIA, weighing 4,580 kg in its launch configuration, will be positioned at 146°E in geosynchronous transfer orbit and is expected to become operational later this year. The satellite, with a lifespan of five years, will significantly enhance Indonesia's telecommunications capabilities. Operating on the Ka-band, SATRIA will transmit over 150 gigabits per second to various areas in Indonesia, including 90,000 schools, 40,000 hospitals, and public buildings, as well as regional government sites that currently lack satellite or terrestrial infrastructure. By connecting these areas, SATRIA aims to bridge the digital divide and contribute to the development of digital infrastructure in the country.
Thales Alenia Space, the manufacturer of SATRIA, expressed pride in achieving this important milestone. Hervé Derrey, CEO of Thales Alenia Space, highlighted the significance of SATRIA as the first Very High Throughput Satellite (VHTS) in Indonesia and the most powerful in the Asian region. Thales Alenia Space utilized its Spacebus NEO chassis and high-throughput payloads to develop SATRIA. Adi Rahman Adiwoso, CEO of the PSN consortium, the contractor for SATRIA, stated that the satellite's capacity is over three times that of the existing national capacities, making it a potential solution to Indonesia's digital divide.
The PSN Consortium formed Satelit Nusantara Tiga (SNT) as the operating company for the SATRIA project. The majority shareholders of SNT are PSN and PT Pintar Nusantara Seghtera (Pintar), and they will retain majority ownership throughout the project's life cycle. The terrestrial infrastructure, including the main control center (Primary Satellite Center) and the network center (Network Operation Center), located in Cikarang, West Java, and a reserve control station in Banjarmasin, South Kalimantan, are already fully operational. PSN collaborated with Kratos Defense and Hughes Network Systems for communication and support networks, with Kratos Defense providing SATRIA Satellite Carriers Spectrum Monitoring (CSM) and Monitoring & Control (M&C) devices, and Hughes Network offering an IP Processing Hub for SATRIA. PSN subsidiary PT Satelit Nusantara Tiga will be responsible for operating the SATRIA satellite for a period of 15 years.
