Reconfiguration of Sun-Earth Libration Point Formations Using Solar Radiation Pressure

Formation flying reconfiguration manoeuvres via environmental forces in highly elliptical orbits

“…(Williams & Wang, 2002) examines the proper use of a solar wing in order to maintain a desired formation. Several studies have been made on the use of SRP to control formation flying around the L2 libration point in the Sun-Earth system, like the ones conducted by (Shahid & Kumar, 2010, or by (Li & Williams, 2006) in which reconfiguration of formations near one of the Sun-earth Libration points is examined. In (Kumar et al, 2014) both the SRP and aerodynamic forces are exploited in order to maintain satellite formations by controlling SRP or aerodynamic flaps, although these forces are exploited separately by considering firstly a Low Earth Orbit (LEO) and secondly a geostationary orbit.…”

On Utilization of Solar Sails in Triangular Libration Point Missions in the Earth-Moon System

“…Due to this property, instead of the tight control strategy, we took a loose one. The optimum feedback control law used in the work is similar to the one used in previous works [7][8] , but these works were mainly about the applications of solar sailing control in the missions around collinear libration point. For applications of solar sailing control around triangular libration point, seldom work has been done.…”
