This attribute sets the values for Geodetic elements used to define the spacecraft's Initial State.
Astrogator <Satellite Object Path> SetValue <Astrogator Object Path>.Geodetic.<Element> <Value> <Unit>
If you select Geodetic as the Coordinate Type, the following elements need to be specified:
Element | Description |
---|---|
Radius | Radius is measured from the center of the Earth. Specified as distance above or below the reference ellipsoid. |
Altitude | Altitude is measured along an outward normal to the surface of the ellipsoid. |
Latitude | Measured in degrees from -90.0 deg to +90.0 deg. The geodetic latitude of a point is the angle between the normal to the reference ellipsoid and the equatorial plane. |
Longitude | Measured in degrees from -360.0 deg to +360.0 deg. The longitude of a point is the angle between the projection of the position vector in the equatorial plane and the prime meridian. |
RadiusRate | The rate of change of the radius. |
AltitudeRate | The rate of change of the altitude. |
LatitudeRate | The rate of change of the satellite's latitude. |
LongitudeRate | The rate of change of the satellite's longitude. |
