TheAtlantic Constellation (Constelación Atlántica) is a futuresatellite constellation ofEarth observation satellites under development bySpain andPortugal, funded by theEuropean Union (EU)[1][2][3][4] and coordinated by theEuropean Space Agency (ESA),[5] with additional contributions by theUnited Kingdom (UK), via theUK 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] withrevisit times of 24 hours, thrice shorter thanCopernicus.[10] The project's first satellite(Atlantic Constellation Pathfinder) is expected to be launched by theUK Space Agency in 2026.[10]
Spain will contribute 8 of the satellites. The contract to build them was awarded to the UK-basedOpen 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, andInternet of Things connectivity.[8] Portugal will contribute other 8 satellites. The UK will launch its single satellite, also built byOpen Cosmos, to the sameorbital plane as 3 of the Portuguese spacecraft. This is expected to increase the revisit frequency for the first orbital plane by 33%.[6]
