 ApoapsisAltitudeShape |
Describes the shape of the
ellipse. Uses Distance dimension. |
| ApoapsisAltitudeSize |
Measured from the "surface"
of the Earth to the points of maximum and minimum radius in the
orbit. For these values, the surface of the Earth is modeled as a
sphere whose radius equals the equatorial radius of the Earth. Uses
Distance dimension. |
| ApoapsisRadiusShape |
Describes the shape of the
ellipse. Uses Distance dimension. |
| ApoapsisRadiusSize |
Measured from the center of
the Earth to the points of maximum and minimum radius in the orbit.
Uses Distance dimension. |
| ArgOfLatitude |
The sum of the True Anomaly
and the Argument of Perigee. Uses Angle Dimension. |
| ArgOfPeriapsis |
The angle from the
ascending node to the eccentricity vector (lowest point of orbit)
measured in the direction of the satellite's motion and in the
orbit plane. Uses Angle Dimension. |
| EccentricAnomaly |
Angle measured with origin
at the center of the ellipse from the direction of perigee to a
point on a circumscribing circle from which a line perpendicular to
the SMA intersects the position of the satellite on the ellipse.
Uses Angle Dimension. |
| Eccentricity |
Describes the shape of the
ellipse (a real number >= 0 and <1, where="" 0="a"
circular="" orbit).="" dimensionless.=""></1,> |
| ElementType |
Which type of element
(osculating or mean). |
| Inclination |
The angle between the
angular momentum vector (perpendicular to the plane of the orbit)
and the inertial Z axis. Uses Angle Dimension. |
| LAN |
The Earth-fixed longitude
where the satellite has crossed the inertial equator (the
intersection of the ground track and the inertial equator) from
south to north based on an assumption of two-body motion. Uses
Angle dimension. |
| MeanAnomaly |
The angle from the
eccentricity vector to a position vector where the satellite would
be if it were always moving at its average angular rate. Uses Angle
Dimension. |
| MeanMotion |
The uniform rate of the
satellite in a circular orbit of the same period, typically
expressed as degrees or radians per second, or as revolutions per
day. Uses AngleRate dimension. |

Describes the shape of the
ellipse. Uses Distance dimension. |
| PeriapsisAltitudeSize |

| Period |
The duration of one orbit,
based on assumed two-body motion. Uses Time dimension. |
| RAAN |
The angle from the inertial
X axis to the ascending node measured in a right-handed sense about
the inertial Z axis in the equatorial plane. Uses Angle
Dimension. |
| SemiMajorAxis |
One-half the distance along
the long axis of the elliptical orbit. Uses Distance
Dimension. |
| TimePastAscNode |
The elapsed time since the
last ascending node crossing based on assumed two-body motion. Uses
Time Dimension. |

The elapsed time since the
last perigee passage based on assumed two-body motion. Uses Time
Dimension. |
| TrueAnomaly |
The angle from the
eccentricity vector (points toward perigee) to the satellite
position vector, measured in the direction of satellite motion and
in the orbit plane. Uses Angle Dimension. |
