Class AngularRadioRefractionModifier

java.lang.Object

org.orekit.estimation.measurements.modifiers.AngularRadioRefractionModifier

All Implemented Interfaces:

EstimationModifier<AngularAzEl>, ParameterDriversProvider

public class AngularRadioRefractionModifier
extends Object
implements EstimationModifier<AngularAzEl>

Class modifying theoretical angular measurement with tropospheric radio refractive index. A radio ray passing through the lower (non-ionized) layer of the atmosphere undergoes bending caused by the gradient of the relative index. Since the refractive index varies mainly with altitude, only the vertical gradient of the refractive index is considered here. The effect of tropospheric correction on the angular measurement is computed directly through the computation of the apparent elevation angle.
