Description

Object Model

Public Methods

Export

Exports the ephemeris file.

Public Properties

CentralBodyName	The central body of the satellite.
CoordinateSystem	Whether the resulting data file should be in the Fixed, J2000, or Inertial coordinate system. If Earth or the Sun is the central body, the Inertial coordinate system is not an available option.
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.
