Geodetic

This attribute retrieves the values for Geodetic elements used to define the spacecraft's Initial State.

Syntax

Astrogator_RM <Satellite Object Path> GetValue <Astrogator Object Path>.Geodetic.<Element>

Description

If you select Geodetic as the Coordinate Type, the following six 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.
