AccelKepler

class ssapy.accel.AccelKepler(mu=398600441800000.0)[source][source]

Bases: Accel

Keplerian acceleration. I.e., force is proportional to 1/|r|^2.

Parameters:: mu (float, optional) – Gravitational constant of central body in m^3/s^2. (Default: Earth’s gravitational constant in WGS84).

Methods Summary

__call__(r, v, t, **kwargs)

Evaluate acceleration at particular place/moment.
