‘Artificial star’ helps test satellite navigation systems (photo)

Within an office complex along the Dutch coast lies an artificial star.

It isn’t an actual star. The complex is the European Space Agency‘s (ESA) European Space Research and Technology Centre (ESTEC), and its artificial star consists of a rotating table before a point of light that simulates the color and brightness of a given star. Engineers use this room to test star trackers.
