Public Methods

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

Public Properties

AvailableBodyNames	Gets a list of available body names.
BodyName	Body name.
EphemerisInterval	Get the propagator's ephemeris interval.
Segments	Get the segment list.
Spice	Name of SPICE file.
Step	Step size. Uses Time Dimension.

Example

Set the satellite to use the SPICE propagator

[C#]

// Set propagator to SPICE
satellite.SetPropagatorType(AgEVePropagatorType.ePropagatorSPICE);

// Get the SPICE propagator
IAgVePropagatorSPICE propagator = satellite.Propagator as IAgVePropagatorSPICE;

Configure the SPICE propagator

[C#]

// Set the SPICE file
propagator.Spice = spiceFile;

// Configure time period
propagator.EphemerisInterval.SetExplicitInterval("1 Jan 2012 12:00:00.000", "2 Jan 2012 12:00:00.000");
propagator.Step = 60.0;
propagator.BodyName = "-200000";

// Propagate
propagator.Propagate();

Configure the SPICE propagator

[Visual Basic .NET]

' Set the SPICE file
propagator.Spice = spiceFile

' Configure time period
propagator.EphemerisInterval.SetExplicitInterval("1 Jan 2012 12:00:00.000", "2 Jan 2012 12:00:00.000")
propagator.[Step] = 60
propagator.BodyName = "-200000"

' Propagate
propagator.Propagate()

Set the satellite to use the SPICE propagator

[Visual Basic .NET]

' Set propagator to SPICE
satellite.SetPropagatorType(AgEVePropagatorType.ePropagatorSPICE)

' Get the SPICE propagator
Dim propagator As IAgVePropagatorSPICE = TryCast(satellite.Propagator, IAgVePropagatorSPICE)

Set satellite propagator to SPICE and propagate

[Python - STK API]

# IAgSatellite satellite: Satellite object
# IAgStkObjectRoot root: STK Object Model Root
satellite.SetPropagatorType(AgEVePropagatorType.ePropagatorSPICE)
propagator = satellite.Propagator
propagator.Spice = r'C:\Program Files\AGI\STK 12\STKData\Spice\planets.bsp'   # Make sure this is a valid path
propagator.BodyName = 'MARS'

propagator.EphemerisInterval.SetImplicitInterval(
    root.CurrentScenario.Vgt.EventIntervals.Item("AnalysisInterval"))  # Link to scenario period
propagator.Step = 60.0
propagator.Propagate()

Set satellite propagator to SPICE and propagate

[MATLAB]

% IAgSatellite satellite: Satellite object
% IAgStkObjectRoot root: STK Object Model Root
satellite.SetPropagatorType('ePropagatorSPICE');
propagator = satellite.Propagator;
propagator.Spice = 'C:\Program Files\AGI\STK 12\STKData\Spice\planets.bsp';   % Make sure this is a valid path
propagator.BodyName = 'MARS';

propagator.EphemerisInterval.SetImplicitInterval( ...
    root.CurrentScenario.Vgt.EventIntervals.Item("AnalysisInterval")) % Link to scenario period
propagator.Step = 60.0;
propagator.Propagate();
