All Implemented Interfaces:

EstimationModifier<RangeRate>, ParameterDriversProvider

public class RelativisticClockRangeRateModifier
extends AbstractRelativisticClockModifier
implements EstimationModifier<RangeRate>

Class modifying theoretical range-rate measurement with relativistic frequency deviation. It works only with orbit-based states.

Relativistic clock correction is caused by the motion of the satellite as well as the change in the gravitational potential
