Six Portuguese-made satellites were successfully launched on 30 March from California aboard a SpaceX rocket. The mission marks a significant step toward establishing a robust, dual-use maritime navigation service for both civilian and military applications, officials said.
The satellites represent Portugal’s contribution to the Atlantic Constellation, a high-resolution, 12-satellite Earth-observation network started with Spain in 2025.
Once fully integrated, the system is set to deliver a real-time information service to vessels at sea, operating in a manner similar to road traffic alerts. This service will offer crucial updates, including weather and pirate warnings, distress requests, and notification of floating icebergs and oil spills. The network is designed to ensure affordable communication access for any ship at sea.

Beyond maritime security, the Atlantic Constellation’s data will reinforce dual-use capabilities across Portugal and Europe, providing crucial information for defence, security, disaster response, precision agriculture, carbon mapping, and wider environmental monitoring.
Initial data is expected to become available within three months, though the full navigation service will not be fully operational until 2027 when all 12 satellites are successfully in orbit.
Portugal’s economy minister Castro Almeida celebrated the launch, describing it as the “most striking day” for Portugal’s engagement in space. He also confirmed future plans, noting that additional satellites are scheduled for launch later this year, alongside the development of a domestic launcher facility in the Azores islands.
