Description

SGP4 propagator interface.

Public Methods

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

Public Properties

AutoUpdate	Allows configuring the auto-update parameters and settings.
AutoUpdateEnabled	Whether automatic update is enabled.
CommonTasks	Most commonly used tasks such as importing of TLEs, etc.
EphemerisInterval	The propagator's ephemeris interval.
Segments	Get the element set list.
Settings	Propagator settings.
StartTime	This property is deprecated. Use EphemerisInterval to configure the propagation interval. Start time. Uses DateFormat Dimension.
Step	Step size. Uses Time Dimension.
StopTime	This property is deprecated. Use EphemerisInterval to configure the propagation interval. Stop time. Uses DateFormat Dimension.
UseScenarioAnalysisTime	This property is deprecated. Use the new Timeline API components to configure the propagator's analysis time. Whether the scenario analysis start/stop times shall be used.

Example

Set the satellite to use the SGP4 propagator

[C#]

// Set propagator to SGP4
satellite.SetPropagatorType(AgEVePropagatorType.ePropagatorSGP4);

// Get the SGP4 propagator
IAgVePropagatorSGP4 propagator = satellite.Propagator as IAgVePropagatorSGP4;

Configure the SGP4 propagator with file source

[C#]

// Configure propagator's TLE file path
propagator.CommonTasks.AddSegsFromFile("2215", tleFilePath);

// Propagate
propagator.Propagate();

Configure the SGP4 propagator with online source

[C#]

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

// Add segments
propagator.CommonTasks.AddSegsFromOnlineSource("25544");

// Propagate
propagator.Propagate();

Configure the SGP4 propagator with file source

[Visual Basic .NET]

' Configure propagator's TLE file path
propagator.CommonTasks.AddSegsFromFile("2215", tleFilePath)

' Propagate
propagator.Propagate()

Configure the SGP4 propagator with online source

[Visual Basic .NET]

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

' Add segments
propagator.CommonTasks.AddSegsFromOnlineSource("25544")

' Propagate
propagator.Propagate()

Set the satellite to use the SGP4 propagator

[Visual Basic .NET]

' Set propagator to SGP4
satellite.SetPropagatorType(AgEVePropagatorType.ePropagatorSGP4)

' Get the SGP4 propagator
Dim propagator As IAgVePropagatorSGP4 = TryCast(satellite.Propagator, IAgVePropagatorSGP4)

Set satellite propagator to SGP4 and propagate

[Python]

# IAgSatellite satellite: Satellite object
satellite.SetPropagatorType(4) # ePropagatorSGP4
propagator = satellite.Propagator
propagator.UseScenarioAnalysisTime
propagator.CommonTasks.AddSegsFromOnlineSource('25544') # International Space Station
propagator.AutoUpdateEnabled = True
propagator.Propagate()

Set satellite propagator to SGP4 and propagate

[MATLAB]

% IAgSatellite satellite: Satellite object
satellite.SetPropagatorType('ePropagatorSGP4');
propagator = satellite.Propagator;
propagator.UseScenarioAnalysisTime;
propagator.CommonTasks.AddSegsFromOnlineSource('25544'); % International Space Station
propagator.AutoUpdateEnabled = true;
propagator.Propagate;
