Apparent LLA State

The apparent position and velocity of the object, expressed in LLA elements, as a function of time. The coordinate system is the requested frame of the scenario's central body. The apparent position is computed with respect to the scenario's central body; the rates are computed as observed in the scenario central body requested frame.

Available for these objects: Planet

Type: Time-varying data.

Data Provider Groups

Name	Description
TrueOfDateRotating	A variation of the Fixed system where pole wander is ignored. The equator is the same as the TrueOfDate equator and the frame spins about the TrueOfDate z-axis.
Fixed	A coordinate system attached to the central body and rotating with it. The z-axis is nominally along the rotation axis.

Name	Dimension	Type	Description
Time	Date	Real Number or Text	Time.
Lat	Latitude	Real Number or Text	The detic latitude (i.e., angle between the detic subpoint's surface normal vector and the XY plane.).
Lon	Longitude	Real Number or Text	The detic longitude (i.e., angle from the X-axis locating the projection of the detic subpoint's surface normal vector onto the XY plane.) Longitude increases in the direction found using the right-hand rule about the Z-axis.
Alt	Distance	Real Number	The altitude value (i.e., magnitude of the relative position vector between the object and its detic subpoint).
Lat Rate	AngleRate	Real Number	The rate of change of the detic latitude.
Lon Rate	AngleRate	Real Number	The rate of change of the detic longitude.
Alt Rate	Rate	Real Number	The rate of change of the altitude value.
