Unseenlabs will launch BRO-21, its latest radio frequency (RF) detection satellite, on May 2 at 11:59 p.m. PT. (May 3 at 08:59 a.m. France Time) aboard a SpaceX Falcon 9 as part of the CAS500-2 mission from Vandenberg Space Force Base in California. Payload integration is managed by Exolaunch.
With this launch, the Unseenlabs constellation will reach 21 satellites, a milestone that directly enhances the company's core capabilities: faster revisit times over any given area of the ocean, and increasingly precise geolocation of RF signals emitted by vessels at sea.
A denser constellation, sharper maritime surveillance
Each satellite added to the Unseenlabs network compounds the value of the whole. A 21-satellite constellation means more frequent passes, shorter gaps in coverage, and tighter constraints on where and when a vessel can go undetected. For the operators, navies, coast guards, and insurers who rely on Unseenlabs data, this translates directly into more timely and reliable data.
Sovereign technology, global reach
BRO-21 is a further demonstration of Unseenlabs' ability to build, deploy, and operate a high-performance space-based RF detection system at scale. From its orbit, the satellite will join a constellation that monitors maritime activity across every ocean, delivering coverage that no surface-based system can match.
Next horizons
BRO-21 is one step in a longer journey. Unseenlabs is already preparing the second generation of satellites platforms built to go further, monitor more, and serve a broader range of use cases across both maritime, land and space environments.
