BRO (Breizh Reconnaissance Orbiter) developed by UnseenLabs, are a series of satellites providing a spectrum monitoring and electromagnetic intelligence service (SIGINT) for maritime and aerial traffic surveillance.

The satellites, built by GOMSpace, is a 6U CubeSat featuring the UnseenLabs built spectrum monitoring payload.

This is the first step towards a future constellation using advanced spectrum monitoring dedicated to a disruptive maritime surveillance service.

UnseenLabs will launch 5 to 6 more satellites in 2020.
