pymgp.satorb.keplernu#
- pymgp.satorb.keplernu(nu, ecc)[source]#
Compute mean and eccentric anomaly from true anomaly (Kepler’s equation).
- Parameters:
- nuarray_like
True anomaly (radians)
- eccarray_like
Eccentricity (unity)
- Returns:
- Marray_like
Mean anomaly (radians)
- Earray_like
Eccentric anomaly (radians)
Notes
This routine should only be used for elliptical orbits. Parabolic and hyperbolic orbits are not supported and give false results (this is nowhere checked for).
