public class RelativisticJ2ClockOneWayGNSSPhaseModifier
extends AbstractRelativisticJ2ClockModifier
implements EstimationModifier<OneWayGNSSPhase>

Class modifying theoretical one-way phase measurements with relativistic J2 clock correction.

Relativistic clock correction of the effects caused by the oblateness of Earth on the gravity potential.

The time delay caused by this effect is computed based on the orbital parameters of the emitter's orbit.
