GMV is evaluating image-based navigation software for ESA's Asteroid Impact Mission by having its navigation camera scrutinise imagery that ESA’s Rosetta comet chaser acquired during its 2010 flyby of the 100 km-diameter Lutetia asteroid, on the way to its Comet 67P/Churyumov–Gerasimenko. The software calculates the spacecraft's position in space based on the changing position of surface features on the asteroid.
