org.orekit.estimation.measurements.modifiers.BaseRangeTroposphericDelayModifier

Direct Known Subclasses:

BistaticRangeTroposphericDelayModifier, RangeTroposphericDelayModifier

public abstract class BaseRangeTroposphericDelayModifier
extends Object

Base class modifying theoretical range measurements with tropospheric delay. The effect of tropospheric correction on the range is directly computed through the computation of the tropospheric delay. In general, for GNSS, VLBI, ... there is hardly any frequency dependence in the delay. For SLR techniques however, the frequency dependence is sensitive.
