SatelliteOrbit

Satellite orbit from 2LE or TLE/3LE

class SatelliteCameraViewer.SatelliteCamera.SatelliteOrbit.SatelliteOrbit

Bases: object

Attributes:

tle

tle - return array of TLE strings (2 or 3 lines long)

Methods

eci_position_vector(obs_time)	Returns ECI (Earth-Centered Inertial) position (km) at UTC time obs_time.
eci_velocity_vector(obs_time)	Returns ECI (Earth-Centered Inertial) velocity (km/s) at UTC time obs_time.
icrs(obs_time)	icrs - convert satellite and time into a ICRS value
sat_in_eclipse(obs_time)	in_eclipse - Returns True if saetellite is in Earth's umbra (full shadow).
sat_lon_lat_alt(obs_time)	sat_lon_lat_alt - Return satellite geodetic lat, lon, alt.
