2025年10月16日According to Satnow’s report on January 19th, the Space Flight Laboratory (SFL) has confirmed the successful launch and deployment of Norway’s NorSat-4 maritime monitoring microsatellite. This is the seventh spacecraft developed by SFL for the Norwegian Space Agency (NOSA). “NorSat-4” is equipped with the fifth generation Automatic Identification System (AIS) tracking receiver and a pioneering low light imaging camera.
The NorSat-4 is built on the SFL space validated 35 kilogram Defiant microsatellite platform and was launched from Vandenberg Space Force Base in California on January 14th aboard SpaceX’s Transporter-12 carpool launch mission. The ground control center has confirmed the establishment of communication with the spacecraft.
Dr. Robert E. Zee, Director of SFL, stated that ‘NorSat-4’ consolidates Norway’s leading position in the field of space-based maritime situational awareness through its cost-effective small satellite project. The newly added low light imaging camera in this mission continues the tradition of the Norwegian Space Agency testing cutting-edge onboard technologies. ”
The low light optical camera enhances the Norwegian Coast Guard’s ability to detect and track ships in its Arctic territorial waters by supplementing AIS receivers on satellites. Some maritime vessels may deactivate their AIS transmitters or forge signals with incorrect location/identity data for malicious purposes. Safran Reosc, a French company, has signed a contract with a Norwegian defense research institution to manufacture this camera for optical detection of ships over 30 meters in length in the dark Arctic environment.
