The Atlantic Constellation (Constelación Atlántica) is a future satellite constellation of Earth observation satellites under development by Spain and Portugal, funded by the European Union (EU)[1][2][3][4] and coordinated by the European Space Agency (ESA),[5] with additional contributions by the United Kingdom (UK), via the UK Space Agency.[6][7] The constellation, focused on coastal surveillance, environmental management, and climate monitoring,[8] will consist of high and very high resolution sub-spectral and multi-spectral Earth observation satellites[9] with revisit times of 24 hours, thrice shorter than Copernicus.[10] The project's first satellite (Atlantic Constellation Pathfinder) is expected to be launched by the UK Space Agency in 2026.[10]

Satellites

Spain will contribute 8 of the satellites. The contract to build them was awarded to the UK-based Open Cosmos in October 2025. These satellites, expected to be delivered by 2027, will be equipped with high-resolution multispectral optical cameras, GNSS reflectometry receivers, AIS receivers, and Internet of Things connectivity.[8] Portugal will contribute other 8 satellites. The UK will launch its single satellite, also built by Open Cosmos, to the same orbital plane as 3 of the Portuguese spacecraft. This is expected to increase the revisit frequency for the first orbital plane by 33%.[6]
