AbstractA preliminary investigation of the early warning of solar storms caused by Coronal Mass Ejection has been carried out. A long warning time could be obtained with a sailcraft synchronous with the Earth-Moon barycenter, and stationed well below the L1 point. In this paper, the theory of heliocentric synchronous sailcraft is set up, its perturbed orbit is analyzed, and a potential solution capable of providing an annual synchrony is carried out. A simple analysis of the response from a low-mass electrochromic actuator for the realization of station-keeping attitude maneuvers is put forwards, and an example of propellantless re-orientation maneuver is studied.
HighlightsThis paper regards a solution to geomagnetic storms caused by Coronal Mass Ejection.An early-warning mission concept by photon sailcraft is introduced.The sailcraft is not constrained around the Sun-Earth L1 point.Heliocentric synchrony-on-average is computed via small attitude maneuvers.Sail maneuver propellantless electro-chromic devices are preliminarily investigated.
