Class TDOAIonosphericDelayModifier

java.lang.Object

org.orekit.estimation.measurements.modifiers.TDOAIonosphericDelayModifier

All Implemented Interfaces:

EstimationModifier<TDOA>, ParameterDriversProvider

public class TDOAIonosphericDelayModifier
extends Object
implements EstimationModifier<TDOA>

Class modifying theoretical TDOA measurements with ionospheric delay.

The effect of ionospheric correction on the TDOA is a time delay computed directly from the difference in ionospheric delays for each downlink.

The ionospheric delay depends on the frequency of the signal.
