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