Class ITURP834AtmosphericRefraction

java.lang.Object
org.orekit.models.earth.ITURP834AtmosphericRefraction
All Implemented Interfaces:
Serializable, AtmosphericRefractionModel
public class ITURP834AtmosphericRefraction extends Object implements AtmosphericRefractionModel
Implementation of refraction model for Earth exponential atmosphere based on ITU-R P.834 recommendation.

This class implements the ray bending part, i.e. section 1 of the recommendation. The excess radio path length part of the model, i.e. section 6 of the recommendation, is implemented in the ITURP834PathDelay class.
