Bases: IPropagator

Class defining the SGP4 propagator.

Overview

Methods

propagate

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

Properties

step	Step size. Uses Time Dimension.
segments	Get the element set list.
automatic_update_enabled	Whether automatic update is enabled.
automatic_update_settings	Allow configuring the auto-update parameters and settings.
common_tasks	Most commonly used tasks such as importing file data, etc.
settings	Propagator settings.
ephemeris_interval	Get the propagator’s ephemeris interval.
international_designator	International designation of the satellite.

Examples

Set satellite propagator to SGP4 and propagate

# Satellite satellite: Satellite object
satellite.set_propagator_type(PropagatorType.SGP4)
propagator = satellite.propagator
propagator.ephemeris_interval.set_implicit_interval(
    root.current_scenario.analysis_workbench_components.time_intervals.item("AnalysisInterval")
)  # Link to scenario period
propagator.common_tasks.add_segments_from_online_source("25544")  # International Space Station
propagator.automatic_update_enabled = True
propagator.propagate()
