heyoka.model.gpe_is_deep_space(n0: float, e0: float, i0: float) bool#

Check whether a GPE is deep-space.

Added in version 7.0.0.

This function takes in input the mean motion, eccentricity and inclination from a general perturbations element set (GPE), and determines whether or not the propagation of the GPE requires the SDP4 deep-space algorithm.

Parameters:
  • n0 – the mean motion from the GPE (in [rad / min]).

  • e0 – the eccentricity from the GPE.

  • i0 – the inclination from the GPE (in [rad]).

Returns:

a flag signalling whether or not the input GPE requires deep-space propagation.
