ostk.physics.environment.Ephemeris

class Ephemeris

Bases: pybind11_object

Abstract base class for ephemeris models.

An ephemeris provides the position and orientation of celestial objects as a function of time. This is the base class for various ephemeris implementations including Analytical and SPICE-based ephemerides.

Returns:

The reference frame.

Return type:

Frame

is_defined(self: ostk.physics.environment.Ephemeris) → bool
