PropagatorJ4Perturbation

class ansys.stk.core.stkobjects.PropagatorJ4Perturbation

Bases: IPropagator

Class defining the J4 perturbation propagator.

Overview

Methods

propagate

Propagates the satellite’s path using the specified time interval.

Properties

step	Step size. Uses Time Dimension.
initial_state	Get the initial state.
ephemeris_interval	Get the propagator’s ephemeris interval.
propagation_frame	Get or set the propagation frame.
supported_propagation_frames	Return supported propagation frames.
display_coordinate_type	The propagator’s display coordinate type.

Examples

Set satellite propagator to J4 and assign cartesian position

# Satellite satellite: Satellite object
satellite.set_propagator_type(PropagatorType.J4_PERTURBATION)
propagator = satellite.propagator
icrfCoordinates = [6678.14, 0, 0, 0, 6.78953, 3.68641]
propagator.initial_state.representation.assign_cartesian(CoordinateSystem.ICRF, *icrfCoordinates)
propagator.propagate()
