Image : PROBA-3 formation flying mission will rely on GNC software developed by NGC
Two PROBA-3 satellites are being designed: an Occulter satellite whose mission is to block the very intense light emission from the main solar disk and the Coronagraph, whose scientific mission is to align itself accurately with the Occulter and the sun in order to observe the sun corona. In addition to this scientific objective, PROBA-3 will also have the technological mission of demonstrating in orbit the formation flight of satellites.
