Inherits Rotation

Members

Name	Documentation	Type	Description	Optional
SourceFrame	This value specifies the source frame that is used as the basis for the coordinate transformation. This has to be a valid SPICE name	String	A valid SPICE NAIF name or integer	No
DestinationFrame	This value specifies the destination frame that is used for the coordinate transformation. This has to be a valid SPICE name. If this value is not specified, a reference frame of ‘GALACTIC’ is used instead	String	Value of type ‘String’	Yes
FixedDate	A time to lock the rotation to. Setting this to an empty string will unlock the time and return to rotation based on current simulation time	String	A time to lock the rotation to	Yes
TimeFrame	The time frame in which the spice kernels are valid	Table	TimeFrame	Yes

Inherited members from Rotation

Name	Documentation	Type	Description	Optional
Type	The type of the rotation that is described in this element. The available types of rotations depend on the configuration of the application and can be written to disk on application startup into the FactoryDocumentation	String	Must name a valid Rotation type	No
