  • Direct Known Subclasses:

    public abstract class BaseRangeRateIonosphericDelayModifier
    extends Object
    Base class modifying theoretical range-rate measurement with ionospheric delay. The effect of ionospheric correction on the range-rate is directly computed through the computation of the ionospheric delay difference with respect to time. 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.
