Access AER Data
Provides azimuth, elevation, and range (AER) over time between access pairs in the strands of a Chain. The report is organized into subsections, one subsection per pair. Each subsection reports over intervals that are the intersection of the pair's access intervals with the Chain's complete access intervals.Azimuth and elevation angles are reported with respect to the Default AER frame of the first object.
The object class determines the Default AER frame- Facilities, places, targets, area targets, and line targets use NorthEastDown
- Aircraft, ships, ground vehicles, planets and stars use VVLH CBF
- Satellites, missiles, and launch vehicles use VVLH CBI
- Child objects use the default frame of their parent except that linked transmitters, receivers, and radars use the parent of the linked antenna
- See the Access AER Data data provider for the description of each frame.
Available for these objects: Chain
Type: Time-varying data. Intended to be used only with elements from this same data provider.

Data Provider Elements
| Name | Dimension | Type | Description |
|---|---|---|---|
| Time | Date | Real Number or Text | Time. |
| Azimuth | Angle | Real Number or Text | Dihedral angle from the X-axis to the relative position vector measured about the Z-axis. The value is positive when the vector has a positive Y component. The relative position vector reflects the access settings for light time delay, aberration, and refraction. |
| Elevation | Angle | Real Number or Text | Angle measured from the XY-plane to the relative position vector. The value is positive depending on the sign of the Z component of the vector. See the reference frame description to determine whether a positive or negative Z component leads to a positive elevation angle value. The relative position vector reflects the access settings for light time delay, aberration, and refraction. |
| Range | Distance | Real Number | Magnitude of the relative position vector. The relative position vector reflects the access settings for light time delay, aberration, and refraction. |
| RangeRate | Rate | Real Number | The rate of change of range. |
| AzimuthRate | AngleRate | Real Number | The rate of change of azimuth. |
| ElevationRate | AngleRate | Real Number | The rate of change of the elevation angle. |
| Strand Name | Unitless | Text | The strand name. |
