Lined up with the Sun, Proba-3’s Occulter spacecraft uses its occulting disc to cast a precisely-controlled shadow onto the Coronagraph spacecraft. The pair host multiple positioning technologies to achieve millimetre level precision: GNSS receivers, radio links, optical cameras tracking flashing LEDs, a reflected laser and shadow-detecting sensors.
