Proximity Operations of Formation Flying Spacecraft

Proximity Operations of Formation Flying Spacecraft

Giuseppe Corrao - 1/8/2018

The formation flying concept is becoming really important these days, especially since the development of nano, micro, or small satellites capable of carrying Earth Observation payloads. The usage of this kind of satellite instead of a single, massive satellite improves flexibility and reliability, and greatly reduces cost.
