Collision Avoidance for Satellites in Formation Flying
According to later reports there are more than 18000 artificial satellites in space, with more than 35000 objects larger than 10cm and another million objects large enough to cause serious damage to the satellites. With so many potentially dangerous objects in an orbit around the surface of the earth, a collision-avoidance system becomes often necessary. This problem is of greater concern with the ever-increasing number of satellites that are being planned with multiple new projects involving large constellations.
