Instance methods

altitude_km

Height above the WGS-84 ellipsoid in kilometres.

NOTE: above the ellipsoid, not above mean sea level. The two differ by up to about 100 metres depending on where you are. For pointing an antenna the difference is irrelevant; it is called out because a user entering a GPS altitude is usually entering an ellipsoidal height anyway.

latitude

Source

latitude_radians

Latitude in radians.

Source

longitude

Longitude in degrees, positive east, in -180..180.
