A critical South Atlantic gateway for communications, space infrastructure, and global connectivity.
MissionNEX is developing the South Atlantic Digital Gateway (SADG), a secure, commercially operated space-ground and telecommunications hub in the South Atlantic supporting commercial, civil, and government missions.
Strategic Coverage Position
Secure Infrastructure
LEO • MEO • GEO
The South Atlantic is a critical geographic gap in global communications and space-ground infrastructure where few secure facilities exist today.
The region provides proximity to the South Atlantic Anomaly, an area of particular interest to satellite operators and researchers due to its unique effects on spacecraft systems and orbital operation. Low RF congestion, unique geographic positioning, and future subsea cable connectivity make the SADG a unique platform for communications, space operations, scientific research, and long-term infrastructure investment.
Direct access to key satellite orbits, polar routes, and underserved regions makes the SADG a prime candidate for expanding your mission.
Focused on location predictability with long-term operational assurance.
Minimal RF and spectrum congestion compared to northern hemisphere sites makes deconfliction and onboarding simple.
MissionNEX is developing the South Atlantic Digital Gateway, a secure communications and space infrastructure hub. SADG will combine licensed spectrum, licensed satellite earth stations, long-term site control, multi-orbit backhaul, secure data services, and future fiber integration to support commercial, civil, and government space missions. Our secure data centers are being built to meet the strictest physical and cybersecurity standards.
