Access: AER Data: NorthEastDown

Axes aligned with North (X), East (Y), and Down (Z) of the detic subpoint of the base object (i.e., the detic projection of the base object's position to its central body's ellipsoid. Elevation is measured positive toward the -Z-axis (i.e, Up).

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.
