Access: AER Data: VVLH CBI

Axes aligned with the VVLH axes based on the CBI velocity of the base object. Elevation is measured positive toward the -Z-axis.

Name	Dimension	Type	Description
Access Number	Unitless	Integer	A count of the access intervals.
Time	DateFormat	Real Number	Time.
Azimuth	LongitudeUnit	Real Number	Angle measured from the X-axis of the direction of the relative position vector, positive about the axis used to measure positive elevation.
Elevation	AngleUnit	Real Number	Angle measured from the XY-plane to the direction of the relative position vector.
Range	DistanceUnit	Real Number	Magnitude of the relative position vector. The relative position vector reflects the access settings for light time delay, aberration, and refraction.
AzimuthRate	AngleRateUnit	Real Number	The rate of change of azimuth.
ElevationRate	AngleRateUnit	Real Number	The rate of change of elevation.
RangeRate	Rate	Real Number	The rate of change of range.
Path Delay	TimeUnit	Real Number	The range divided by the speed of light.
From Precision Pass	Unitless	Real Number	The precision pass number of the base object. Applicable only for Satellites.
To Precision Pass	Unitless	Real Number	The precision pass number of the target object. Applicable only for Satellites.
From Precision Path	Unitless	Real Number	The precision path number of the base object. Applicable only for Satellites.
To Precision Path	Unitless	Real Number	The precision path number of the target object. Applicable only for Satellites.
Strand Name	Unitless	Text	The name representing the access.
Local Hour Angle	AngleUnit	Real Number	The local hour angle of the target object with respect to the base object. The local hour angle is the angle from the X-axis of the central body Fixed axes to the projection of the relative position vector into the XY-plane of the central body Fixed axes.
