On routing for extending satellite service life in LEO satellite networks [PDF]
2014 IEEE Global Communications Conference, 2014 We address the problem of routing for extending the service life of satellites in Iridium-like LEO constellations. Satellites in LEO constellations can spend over 30% of their time under the earth's umbra, time during which they are powered by batteries. While the batteries are recharged by solar energy, the depth of discharge they reach during eclipse

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.
