Keplerian Elements
Keplerian elements are a set of six numbers that precisely describe the shape, size, and orientation of an elliptical orbit for a celestial body or spacecraft.
TECHNICAL DEFINITION
Keplerian elements are a set of six classical orbital parameters (semi-major axis, eccentricity, inclination, longitude of the ascending node, argument of periapsis, true anomaly at epoch) that uniquely define the two-body elliptical orbit of a celestial object or spacecraft.
BACKGROUND
Space-based solar power is the concept of collecting solar power in outer space with solar power satellites (SPS) and distributing it to Earth. Its advantages include a higher collection of energy due to the lack of reflection and absorption by the atmosphere, the possibility of very little night, and a better ability to orient to face the Sun. Space-based solar power systems convert sunlight to some other form of energy which can be transmitted through the atmosphere to receivers on the Earth's surface.
