Orbital mission planning indicator

摘要

An orbital mission planning indicator device provides a visual indication of the relationship between the plane of orbit of an artificial earth satellite and the angle of incidence of solar energy thereon, for all seasons of the year and for arbitrary times and places of launch of such satellite. It also provides indications of the relationship of deep space points of interest to the same orbital plane for adaptability of pointable sensors such as telescopes, antennas and solar arrays to orbital missions calling for use of such equipments.
