org.orekit.estimation.measurements.modifiers.AngularIonosphericDelayModifier

All Implemented Interfaces:

EstimationModifier<AngularAzEl>

public class AngularIonosphericDelayModifier
extends Object
implements EstimationModifier<AngularAzEl>

Class modifying theoretical angular measurement with ionospheric delay. The effect of ionospheric correction on the angular measurement is computed through the computation of the ionospheric delay. The spacecraft state is shifted by the computed delay time and elevation and azimuth are computed again with the new spacecraft state. The ionospheric delay depends on the frequency of the signal (GNSS, VLBI, ...). For optical measurements (e.g. SLR), the ray is not affected by ionosphere charged particles.
