Aircraft: Lighting AER: ECIVVLH

Earth centered inertial vehicle velocity local horizontal frame. This frame has the Z axis aligned with the anti-radial direction and the X axis constrained toward the inertial velocity direction. This frame is not restricted to Earth oriented vehicles despite its name.

Name	Dimension	Type	Description
Time	DateFormat	Real Number	Time.
Azimuth	LongitudeUnit	Real Number	Dihedral angle between north vector and velocity vector about the detic nadir vector. The velocity vector is the velocity of the object, as observed in the object's central body fixed coordinate system.
Elevation	AngleUnit	Real Number	Angle between the velocity vector and the local horizontal plane. The velocity vector is the velocity of the object, as observed in the object's central body fixed coordinate system.
Range	DistanceUnit	Real Number	The range (i.e., distance between the primary and secondary object) at the given time.
To Nadir Angle	AngleUnit	Real Number	Angle between the apparent sun direction and the nadir direction where nadir is defined as the direction to the center of the central body.
