public class OneWayGNSSRangeIonosphericDelayModifier
extends BaseOneWayGNSSRangeIonosphericDelayModifier
implements EstimationModifier<OneWayGNSSRange>

Class modifying theoretical range measurement with ionospheric delay.

The effect of ionospheric correction on the range is directly computed through the computation of the ionospheric delay.

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.

Since 10.0, state derivatives and ionospheric parameters derivates are computed using automatic differentiation.

Since:

8.0
