Optus‑X (TD7): Australia’s Secretive High-Capacity Communications Satellite

Overview

Optus‑X, also known as TD7, is a geostationary communications satellite built by Northrop Grumman Innovation Systems for Optus, one of Australia’s major telecommunications providers. Launched aboard SpaceX Falcon 9 Block 5 on November 17, 2024, from Kennedy Space Center’s LC-39A, the mission officially deployed to geostationary transfer orbit (GTO) Optus and the U.S. government refer to the mission as “Optus‑X,” reflecting its dual civilian and military usage.

Purpose & Capabilities

• Secure military communications: The X-band payload supports both civilian and military networks, likely funded in part by Australia’s defense sector.
• Robust messaging and data services: Ideal for government, emergency responders, broadcasters, and remote users.

Orbital Details
Optus‑X (TD7) will operate from a geostationary slot near 87.75° East longitude, a distinctly separate orbital position compared to Optus’s existing fleet (152°–164° East).

Significance

• Marks Optus’s expansion into more secure, government-grade satellite communications
• Reflects growing integration between civilian and defense satellite operations in Australia.
• Enhances Australia’s capability in global satellite-based messaging and connectivity.
