Unseenlabs develops satellite-based radio-frequency detection services that help customers identify and understand activity at sea and beyond. Its technology locates and characterises emissions, including signals from vessels that are not transmitting through conventional identification systems. Founded in France, the company serves public and private organisations worldwide. Building on its maritime monitoring work, Unseenlabs is extending its capabilities across land and space applications, with independently operating satellites providing an additional source of intelligence.
