Description

The STK Ephemeris type for the Export Ephemeris/Attitude Tool.

Public Methods

Exports the ephemeris file.

Public Properties

CentralBodyName	Gets or sets the central body of the coordinate system in which to express the ephemeris.
CoordinateSystem	Gets or sets the coordinate system in which to express the ephemeris. Some frames are allowed for use only when the CentralBodyName is Earth. If Earth or the Sun is the central body, the Inertial coordinate system is not an available option - use ICRF instead.
CovarianceType	Choose to export position covariance (3x3), position/velocity covariance (6x6), or no covariance information. CovarianceType is valid only if the vehicle has ephemeris with covariance.
IncludeInterp	Include or ignore interpolation boundaries.
StepSize	If the Use Ephemeris Steps option is not selected, enter a Step Size to be used for the vehicle.
TimePeriod	Sets the time period. Options are Use Entire Ephemeris - STK creates a data file using the Start and Stop Time specified in the vehicle's Orbit tab or Specify Time Period - STK creates a data file using the Start and Stop Time specified here.
UseVehicleCentralBody	Uses vehicle's central body.
VersionFormat	Provides the option to generate files compatible with prior versions of STK.

Example

Export a vehicle STK ephemeris to an external file

[C#]

// set export parameters
stkEphem.CoordinateSystem = AgEStkEphemCoordinateSystem.eStkEphemCoordinateSystemFixed;
stkEphem.IncludeInterp = true;
stkEphem.VersionFormat = AgEExportToolVersionFormat.eExportToolVersionFormatCurrent;
stkEphem.TimePeriod.TimePeriodType = AgEExportToolTimePeriod.eExportToolTimePeriodSpecify;

// Set the ephemeris to the Scenario start and stop times
stkEphem.TimePeriod.Start = scenario.StartTime;
stkEphem.TimePeriod.Stop = scenario.StopTime;

stkEphem.StepSize.StepSizeType = AgEExportToolStepSize.eExportToolStepSizeEphem;
stkEphem.Export(ephemFilePath);

Export a vehicle STK ephemeris to an external file

[Visual Basic .NET]

' set export parameters
stkEphem.CoordinateSystem = AgEStkEphemCoordinateSystem.eStkEphemCoordinateSystemFixed
stkEphem.IncludeInterp = True
stkEphem.VersionFormat = AgEExportToolVersionFormat.eExportToolVersionFormatCurrent
stkEphem.TimePeriod.TimePeriodType = AgEExportToolTimePeriod.eExportToolTimePeriodSpecify

' Set the ephemeris to the Scenario start and stop times
stkEphem.TimePeriod.Start = scenario.StartTime
stkEphem.TimePeriod.[Stop] = scenario.StopTime

stkEphem.StepSize.StepSizeType = AgEExportToolStepSize.eExportToolStepSizeEphem
stkEphem.Export(ephemFilePath)
