Real Number |
Time. |
| Azimuth |
LongitudeUnit |
Real Number |
Dihedral angle between north vector and velocity
vector about the detic nadir vector. The velocity vector is the
velocity of the object, as observed in the object's central body
fixed coordinate system. |
| Elevation |
AngleUnit |
Real Number |
Angle between the velocity vector and the local
horizontal plane. The velocity vector is the velocity of the
object, as observed in the object's central body fixed coordinate
system. |
| Horiz Rate |
Rate |
Real Number |
Speed in the local horizontal plane, as observed in
the object's central body fixed coordinate system. |
| Velocity |
Rate |
Real Number |
The magnitude of the velocity vector, as observed
in the object's central body fixed coordinate system. |
