RK4Propagator

class ssapy.propagator.RK4Propagator(accel, h)[source][source]

Bases: RKPropagator

Runge-Kutta 4th order numerical integrator.

Parameters:

  • accel (ssapy.Accel) – Accel object containing the acceleration model by which to propagate.

  • h (float) – Step size in seconds. Reasonable values are ~50s for LEO propagations over a ~day for ~meter accuracy, or 1000s for GEO propagations over a few days with ~meter accuracy. For best results, check for convergence.
