Researchers at DTU Space have designed and refined AI-based methods along with advanced digital imaging systems that enable satellites to autonomously detect and track one another from several away. These systems allow them to approach within just a few meters and maintain tightly coordinated formation flying with submillimetre precision.

Each satellite is equipped with a distinct star-like pattern on its surface. Onboard navigation cameras recognize these patterns on the companion satellite and use them to calculate relative position and distance with exceptional accuracy in space. When smaller satellites fly in highly precise formation across distances of hundreds of meters, they can effectively function as a single, large mirror. This concept opens the door to capturing sharper images of distant stars and galaxies than what conventional space telescopes can achieve.

After completing the first scientific observations of the Sun’s corona, DTU Space was given control of the spacecraft for one week to fully test its navigation technology. During this time, the satellites successfully located one another independently, adjusted their trajectories, and aligned in formation with extraordinary precision, comparable to hitting the centre of a coin with a laser from three kilometres away.

With the first dedicated strategy for space research and innovation launched in the end of 2024, the government has identified space as a key area for innovation and economic development, and has doubled the funding for Danish and ESA projects. The strategy also introduced a new national program within Innovation Fund Denmark, where foreign partners can participate and receive funding for R&D together with Danish companies.

Furthermore, the ESA Business Incubator Program (ESA BIC) has been expanded so four Danish Universities participate and support companies in Denmark to stay competitive in today’s rapidly changing space economy.
