Unseenlabs has announced the upcoming launch of BRO-22, the first satellite from a foreign private company to fly aboard Japan’s H3 Launch Vehicle (H3 rocket). Scheduled for June 10, between 09:53 and 11:52 a.m. Japan Standard Time, the launch will take place from the Yoshinobu Launch Complex at Japan Aerospace Exploration Agency (JAXA)’s Tanegashima Space Center. The satellite will be integrated by Space BD. BRO-22 will strengthen Unseenlabs’ space-based RF detection constellation dedicated to maritime surveillance.

Building on the collaborative achievements of Unseenlabs and Space BD, including the Memorandum of Understanding signed in April 2026, this launch will further strengthen the partnership between the two companies. Furthermore, marking the first of many to come, Unseenlabs anticipates that its constellation will also be carried by the H3 rocket in the future

“This collaboration with Space BD and JAXA is important for Unseenlabs,” said Clément Galic, CEO and Co-Founder of Unseenlabs. “Japan is a strategic partner for France, and also for Unseenlabs. We are pleased to launch BRO-22 aboard Japan’s H3 rocket and to work with Space BD and JAXA on this mission. This launch is another step in the development of our constellation and supports our goal of providing reliable RF data for maritime surveillance worldwide.”

As Unseenlabs is already established in the Asia-Pacific region, with an office and team in Singapore, this collaboration with Space BD and JAXA reflects Unseenlabs’ commitment to the region and the company understanding of maritime surveillance challenges.

BRO-22 is a Gen 1 satellite in the Unseenlabs constellation. Like the rest of the constellation, it is based on the company’s exclusive monosatellite technology, meaning it is designed to operate independently from the other satellites.

BRO-22 will be dedicated to maritime surveillance using radio frequency (RF) detection. It will detect RF signals emitted by vessels at sea, further enhancing Unseenlabs’ ability to detect, geolocate, and characterize ships, including those not visible through traditional monitoring systems such as AIS.

RF data collected by Unseenlabs’ satellites helps detect and monitor maritime activity, including undeclared, suspicious, and illegal operations such as:

IUU fishing,
ocean dumping,
operations near critical infrastructure.

Over the coming months, Unseenlabs will launch its first Gen 2 satellites, further enhancing RF signal detection capabilities and expanding the company’s RF applications across sea, land, and space.
