Start with institutions that need a connection
SATRIA, short for Satelit Republik Indonesia, was designed to extend internet access to Indonesian public-service locations that lacked adequate existing connections. The program links a spacecraft to a social objective: enabling institutions such as schools, hospitals and government offices to communicate. Thales Alenia Space built the satellite for the Satelit Nusantara Tiga partnership on behalf of Indonesia’s communications ministry.
The spacecraft launched in June 2023. Its advertised 150 gigabits per second describes aggregate design throughput, not a guaranteed rate for every institution. SATRIA and Nusantara Tiga refer to the same spacecraft project in this context. Treating them as two independent satellites would inflate capacity or launch counts. The program’s success must also be evaluated through the sites and users it actually serves.

A later operating example
In July 2026, Komdigi described using SATRIA capacity at 286 existing access locations while repairs were prepared for a damaged submarine cable segment. The report listed 106 sites in Sangihe, 48 in Sitaro and 132 in Talaud. It described different increases in available bandwidth according to local needs, rather than assigning an identical rate to every location.
Add the three reported site counts: 106 plus 48 plus 132 equals 286. That arithmetic checks the internal consistency of the reported total. It does not measure the number of individual users, their connection quality or how long each site remained available. Nor does a planned cable-repair completion date establish that the repair actually finished on schedule. Different claims require different kinds of evidence.
Check the unit being counted
Original teaching diagram. July 2026 report. 106 + 48 + 132 sites. 286 access locations. Different questions. How many people use them?. How reliably do they work?. A verified site total is useful, but it does not answer every service question.

The last connection is part of the program
Imagine a school with a commissioned satellite terminal but unreliable classroom power and no working local network. Radio capacity can reach the terminal while students still cannot use the lesson materials. A useful deployment therefore includes installation, local distribution, maintenance and support. Teachers and other institutional users also need services suited to their work, not just a large number in a satellite specification.
SATRIA’s public-service focus provides a way to ask better evaluation questions. Which previously underserved locations gained usable access? Does the connection work during the hours when it is needed? Can faults be reported and repaired? How does performance change under shared demand? A satellite program becomes socially valuable through the services enabled on the ground. The spacecraft and its orbital position are essential infrastructure, but the educational or clinical outcome occurs at the receiving end.
