Unseenlabs is a European company headquartered in France and is a pioneer in space-based radio-frequency (RF) detection for Maritime Domain Awareness. The company owns and operates its constellation of satellites. Each satellite is equipped with exclusive, in-house developed technology that enables the detection, characterisation, and geolocation of shipborne RF emitters in maritime areas worldwide, anytime and regardless of weather conditions. Unseenlabs provides its customers with RF data and solutions.

As of August 2024, the Unseenlabs constellation consists of 15 satellites, 2 more satellites will be launched in 2024 with plans to expand to a total of 25 satellites by the end of 2025. Currently, the constellation offers a revisit time of approximately 3 hours, depending on the area of interest and the required level of service. It will be reduced to less than 1 hour once the full constellation is operational. The geolocation of each detected emitter can reach 1 kilometre accuracy. During every single pass, each mono-satellite intercepts RF signals and covers a wide area, up to 300,000 km2 (550 x 550 km or 300 x 300 Nm).

The Unseenlabs constellation is specifically designed to address the gaps in maritime surveillance, particularly those arising from the limitations of the Automatic Identification System (AIS). AIS is a tracking system used on ships and by traffic services to monitor and exchange information such as the ships' identity, position, speed, and course. AIS transponders automatically broadcast this data to nearby ships and shore stations, enhancing maritime safety by preventing collisions and aiding in navigation. While AIS is the most conventional maritime security shipborne system, it can be turned-off voluntarily, easily jammed or spoofed, leading to significant blind spots when monitoring the maritime traffic. By capturing and analyzing RF signals emitted by onboard systems, the Unseenlabs solution provides a more comprehensive and reliable overview of the maritime traffic.
