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. |
| Angle Off
Boresight |
AngleUnit |
Real Number |
The complimentary angle to the elevation (i.e., 90
deg minus the elevation). |
| Horizontal Angle |
AngleUnit |
Real Number |
The apparent angle to the target object from the
base object, defined by arctan(cos(azimuth)/tan(elevation)). |
| Vertical Angle |
AngleUnit |
Real Number |
The apparent angle to the target object from the
base object, defined by arctan(sin(azimuth)/tan(elevation)). |
| Range |
DistanceUnit |
Real Number |
The range (i.e., distance between the primary and
secondary object) at the given time. |
| Distance
Off Boresight |
Unitless |
Real Number |
The apparent angle to the target object from the
base object, defined by tan(angle off boresight). |
