SATRIA‑1 (Nusantara Tiga): Indonesia’s High-Throughput Internet Satellite

Overview & Purpose

SATRIA‑1 (SAteliT Republik IndonesiA), also called Nusantara Tiga, is Indonesia’s first Very High Throughput Satellite (VHTS) built to bridge the digital divide and deliver broadband internet to remote regions, including schools, health facilities, government offices, and rural communities  Boasting a 150 Gbps capacity, it represents the largest internet satellite in Southeast Asia

Manufacturer & Platform

Developed by Thales Alenia Space (France/Italy) on the Spacebus Neo electric platform, SATRIA‑1 features all-electric propulsion for efficient orbit raising and station-keeping. The satellite carries a Ka-band VHTS payload, enabling high-capacity, frequency-reuse Internet coverage across the Indonesian archipelago.

Launch Details

• Launch Date: June 18, 2023 at 22:21 UTC
• Launch Vehicle: SpaceX Falcon 9 Block 5 (booster B1067.12)
• Launch Site: Cape Canaveral SFS, Florida (SLC‑40)
• Orbit Injection: Deployed into a super synchronous transfer orbit; began autonomous orbit raising with electric propulsion
• Operational Geostationary Slot: Near 146° East longitude above eastern Indonesia
• Service Launch: Early posterior testing in October 2023, with full operations expected by late 2023 or early 2024

Ground Segment & Operations

SATRIA‑1 is monitored via eleven ground stations across Indonesia, with primary control centers in Cikarang (Java) and Banjarmasin (Kalimantan). Final payload validation was carried out in late 2023

Strategic Impact

• Enables high-speed internet for underserved communities via VSAT terminals
• Serves public facilities including schools, hospitals, local governments, as well as defense and emergency services
• The 150 Gbps capacity is approximately three times Indonesia’s prior satellite infrastructure
• A key step toward Indonesia’s digital transformation goals, fostering nationwide connectivity and economic development
