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]
In 2025 and 2026, the Spanish company Satlantis launched two precursor satellites: Garai A and Gerai B named after Basque explorer Juan de Garai. The satellites are testing the multispectral instruments ISIM-90 and ISIM-170.[11][12]
Spain will contribute 11 of the Atlantic Constellation satellites. The contract to build the original eight 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] The Spanish satellites will be named by students of Spanish primary and secondary schools.[13] In early 2026, Spanish government approved additional €325 million for development of three further satellites as part of Atlantic Constellation expanded satellite programme ESCA+, bringing the Spanish contribution to 11.[14]
Portugal will contribute other eight satellites. The UK will launch its single satellite, also built by Open Cosmos, to the same orbital plane as three of the Portuguese spacecraft. This is expected to increase the revisit frequency for the first orbital plane by 33%.[6]
