Boundary Target Data
Reports down track and cross track range over time for each boundary point of the AreaTarget/LineTarget for an access involving the AreaTarget/LineTarget and a moving object (or sub-object). The range measures make use of the moving object's reference plane, defined as the plane containing the position vector of the moving object and its velocity vector measured with respect to the object's central body fixed system.While allowed, the data obtained when the From object is not moving is not informative.
Available for these objects: Access
Restrictions: Access - Applies when one object is an AreaTarget or LineTarget.
Type: Interval data. Intended to be used only with elements from this same data provider.

| Time | Date | Real Number or Text | Time. |
| Point Number | Unitless | Integer | Point number. |
| Access Number | Unitless | Integer | A count of the intervals. |
| DownTrack Range | Distance | Real Number | An approximation of the (signed) surface distance between the centric subpoint of the moving object to the projection of the boundary point's centric subpoint to the moving object's reference plane. |
| CrossTrack Range | Distance | Real Number | An approximation to the (signed) surface distance between the boundary point's centric subpoint and the moving object's reference plane. |
| Pass Number | Unitless | Text | Satellite pass number at the stated time. |
