Description

Ballistic propagator interface.

Object Model



Public Methods

Public Method IsImpactLocationTypeSupported Gets a value indicating whether the specified type can be used.
Public Method IsLaunchTypeSupported Gets a value indicating whether the specified type can be used.
Public Method Propagate Propagates the missile's path using the specified time interval.
Public Method SetImpactLocationType Method to set the impact location type.
Public Method SetLaunchType Method to set flight parameters type.

Public Properties

Public Property EphemerisInterval The propagator's ephemeris interval.
Public Property ImpactLocation Get the impact location.
Public Property ImpactLocationSupportedTypes Returns an array of valid choices.
Public Property ImpactLocationType Get impact location type.
Public Property Launch Get launch parameters.
Public Property LaunchSupportedTypes Returns an array of valid choices.
Public Property LaunchType Get flight parameters type.
Public Property StartTime This property is deprecated. Use EphemerisInterval to configure the propagation interval. Start time. Uses DateFormat Dimension.
Public Property Step Step size. Uses Time Dimension.
Public Property StopTime This property is deprecated. Use EphemerisInterval to configure the propagation interval. Stop time. Uses DateFormat Dimension.
Public Property 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.
