The Indonesian government successfully launched the Republic of Indonesia Satellite (Satria-1) from Cape Canaveral Space Force Station, Florida, United States, on Sunday, June 18, 2023, local time.
The US$550 million satellite (approximately Rp 8.2 trillion) is positioned in a geostationary orbit at 146 degrees East Longitude.
Satria-1 boasts a capacity of 150 Gbps using High Throughput Satellite (HTS) Ka-Band frequency technology, claimed to reach nearly 150,000 public service facilities across Indonesia. This capacity makes Satria-1 the largest satellite in Asia and the fifth largest in the world.
With Satria-1 in orbit, Indonesia now has six active Geostationary Orbit (GSO) satellites. The other five GSO satellites are: Indostar 2, Merah Putih, Telkom 3S, Nusantara Satu, and BRIsat.
In addition to GSO satellites, Indonesia also has four active Non-Geostationary Orbit (NGSO) satellites: Lapan-A1, Lapan-A2, Lapan A-3, and Surya Satellite-1 (SS-1), launched in early June 2023.
