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. |
| Range |
DistanceUnit |
Real Number |
The range (i.e., distance between the primary and
secondary object) at the given time. |
| To Nadir Angle |
AngleUnit |
Real Number |
Angle between the apparent sun direction and the
nadir direction where nadir is defined as the direction to the
center of the central body. |
