An earth pole-sitter using hybrid propulsion [PDF]
AIAA/AAS Astrodynamics Specialist Conference, 2010 In this paper we investigate optimal pole-sitter orbits using hybrid solar sail and solar electric propulsion (SEP). A pole-sitter is a spacecraft that is constantly above one of the Earth's poles, by means of a continuous thrust.
