org.orekit.models.earth.EarthITU453AtmosphereRefraction

All Implemented Interfaces:

Serializable, AtmosphericRefractionModel

public class EarthITU453AtmosphereRefraction
extends Object
implements AtmosphericRefractionModel

Implementation of refraction model for Earth exponential atmosphere based on ITU-R P.834-7 recommendation.

Refraction angle is computed according to the International Telecommunication Union recommendation formula. For reference, see ITU-R P.834-7 (October 2015).
