PropagatorSPICE

class ansys.stk.core.stkobjects.PropagatorSPICE

Bases: IPropagator

Class defining the SPICE propagator.

Overview

Methods

propagate

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

Properties

step	Step size. Uses Time Dimension.
spice	Name of SPICE file.
body_name	Body name.
segments	Get the segment list.
available_body_names	Get a list of available body names.
ephemeris_interval	Get the propagator’s ephemeris interval.

Examples

Set satellite propagator to SPICE and propagate

# Satellite satellite: Satellite object
# STKObjectRoot root: STK Object Model Root
satellite.set_propagator_type(PropagatorType.SPICE)
propagator = satellite.propagator
if os.name == "nt":
    installPath = r"C:\Program Files\AGI\STK 12"
else:
    installPath = os.environ["STK_INSTALL_DIR"]
bspPath = ["STKData", "Spice", "planets.bsp"]
propagator.spice = os.path.join(installPath, *bspPath)  # Make sure this is a valid path
propagator.body_name = "MARS"

intvl = root.current_scenario.analysis_workbench_components.time_intervals.item("AnalysisInterval")
propagator.ephemeris_interval.set_implicit_interval(intvl)  # Link to scenario period
propagator.step = 60.0
propagator.propagate()
