Self-organising satellite constellation in geostationary Earth orbit [PDF]

, 2015
This paper presents a novel solution to the problem of autonomous task allocation for a self-organizing satellite constellation in Earth orbit. The method allows satellites to cluster themselves above targets on the Earth’s surface.
