SeriesPropagator

class ssapy.propagator.SeriesPropagator(order=2)[source][source]

Bases: Propagator

Propagate using Taylor series expansion of Keplerian motion. This is quite a bit faster than the full Keplerian propagator, but only valid for short time intervals. Using order=2 for a few seconds of time though is definitely reasonable.

Parameters:

order (int, optional) – Order of series expansion. 1 = constant velocity, 2 = constant acceleration
