In a notable development for international space collaboration, a French maritime surveillance satellite is set to launch aboard Japan’s H3 Launch Vehicle. This event marks the first time a foreign private spacecraft will utilize Japan’s new flagship rocket.

International Collaboration

Unseenlabs, a company based in Rennes, France, has confirmed that its BRO-22 satellite will be part of the launch scheduled for June 10, 2026. The launch will take place from the Yoshinobu Launch Complex at the Tanegashima Space Center, operated by the Japan Aerospace Exploration Agency (JAXA). Space BD, a Japanese space business company, is responsible for integrating the satellite onto the rocket.

This mission is a result of the ongoing partnership between Unseenlabs and Space BD, formalized through a memorandum of understanding signed in April 2026. Unseenlabs plans to continue using the H3 rocket for future constellation launches.

Technological Advancements

The BRO-22 satellite is a Gen 1 model, featuring exclusive monosatellite technology that allows it to operate independently in orbit. Its primary mission is to track radio frequency (RF) signals emitted by vessels at sea, enabling the identification of ships that disable or lack traditional tracking systems such as the Automatic Identification System (AIS).

The data collected by the satellite is crucial for detecting illicit ocean activities, including illegal, unreported, and unregulated (IUU) fishing, ocean dumping, and suspicious activities near critical offshore infrastructure.

Strategic Expansion

This project aligns with Unseenlabs’ broader strategy to expand into the Asia-Pacific market, where it already has a regional office in Singapore. Following the launch of BRO-22, Unseenlabs intends to introduce its first Gen 2 satellites to enhance its signal detection capabilities across sea, land, and space.
