Time. |
| Yaw |
AngleUnit |
Real Number |
The yaw angle for the primary object's ellipsoid at
the given time. The yaw angle locates from the tangential direction
the projection of the major axis of the ellipsoid onto the plane
whose normal is the cross-track direction. |
| Pitch |
AngleUnit |
Real Number |
The pitch angle for the primary object's ellipsoid
at the given time. The pitch angle locates the major axis of the
ellipsoid from the plane whose normal is the cross-track
direction. |
