Each of the retroreflectors, which looks like a small 2.5 cm cube, has the capability to reflect - like a bicycle reflector at night - the laser beam exactly in the direction it was sent from. The precision of these optical devices is such that the reflection of the beam does not deviate by more than 3 mm over a distance of 300 m. This optical guidance system, built in Europe, is a brand new worldwide technology.
