Class RangeRateTroposphericDelayModifier

  • All Implemented Interfaces:
    EstimationModifier<RangeRate>

    public class RangeRateTroposphericDelayModifier
    extends Object
    implements EstimationModifier<RangeRate>
    Class modifying theoretical range-rate measurements with tropospheric delay. The effect of tropospheric correction on the range-rate is directly computed through the computation of the tropospheric delay difference with respect to time. In general, for GNSS, VLBI, ... there is hardly any frequency dependence in the delay. For SLR techniques however, the frequency dependence is sensitive.
