Classes
class	supernovas::DynamicObserver
	An observer whose momentary position and velocity is defined dynamically through a state provider function. More...
class	supernovas::EphemerisObserver
	An observer whose position and velocity is defined by ephemeris data, which can be obtained by the currently configured novas_ephem_provider function. More...
class	supernovas::GeocentricObserver
	An observer location and motion, defined relative to the geocenter, such as for an Earth-orbit satellite, or for a virtual observer located at the geocenter itself. More...
class	supernovas::GeodeticObserver
	An observer location at a geodetic (longitude, latitude, altitude) location at the surface or above it (such as in an aircraft or on balloon). More...
class	supernovas::Observer
	An abstract observer location. More...
class	supernovas::OrbitalObserver
	An observer whose position and velocity is defined by Keplerian orbital parameters around a major Solar-system body (such as the Sun, Moon, major planets, or barycenters). More...
class	supernovas::Site
	An Earth-based (geodetic) observer site location, or a momentary airborne observer location. More...
class	supernovas::SolarSystemObserver
	An observer location anywhere in the Solar System, defined by its momentary barycentric position and velocity vectors. More...

Detailed Description

Defining the observer location, or accessing properties thereof.

Observers may be placed anywhere on Earth, around Earth or anywhere in the Solar system. Earth-based observers have a defining geodetic location, which may be a fixed site on the ground (such as an observatory), or an instantaneous airborne location (such as an airplane or balloon observatory) and ground velocity. Observers may also be placed at virtual locations, such as the geocenter, or the Solar-system barycenter.
