Geodetic Coordinate Type

STK makes the Geodetic coordinate type available only if the coordinate system is set to Fixed.

Geodetic coordinate options

Field	Value
Radius or Altitude	Radius is measured from the center of the Earth. Specified as distance above or below the reference ellipsoid. 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.
Radius Rate or Altitude Rate	The rate of change of the radius or altitude.
Latitude Rate	The rate of change of the satellite's latitude.
Longitude Rate	The rate of change of the satellite's longitude.
