Class 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).
