Array Labs

Array Labs is building clusters of four small radar satellites that fly in close formation, each receiving the echoes of the others' transmissions. A single radar satellite produces a flat image. Four synchronised viewpoints on the same scene carry height as well, so a cluster can map terrain in three dimensions in a single pass, without stitching together repeat visits.

Andrew Peterson and Isaac Robledo founded the company in Palo Alto in 2021 on a manufacturing argument: many identical small radar satellites, built cheaply and flown together, can beat one exquisite satellite on cost, coverage and revisit. The stated goal is a continuously refreshed 3D map of the whole planet, sold into mapping, infrastructure, defence, and the simulated worlds that autonomous machines train in.

Five years in, no cluster is in orbit, and even what has flown is unclear from the outside. SpaceNews reported two demonstration satellites launched in 2024; the company's own releases through mid-2026 say only that it has validated its formation flying and radar technology and is preparing to launch. The performance figures it quotes, twenty-centimetre resolution and contracted bookings in nine figures, are claims made before the product's first flight. The backers are serious, DARPA and the Air Force among the funders and Mitsubishi Electric leading a 2026 round that points the radar at tracking aircraft for Asia-Pacific defence, but the core idea is still undemonstrated in public.
