public class RelativisticClockOneWayGNSSRangeRateModifier
extends AbstractRelativisticClockOnBoardRangeRateModifier<OneWayGNSSRangeRate>

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

Constructor Details

RelativisticClockOneWayGNSSRangeRateModifier

public RelativisticClockOneWayGNSSRangeRateModifier(double gm)

Simple constructor.

Parameters:

gm - gravitational constant for main body in signal path vicinity.

Method Details

modifyWithoutDerivatives

public void modifyWithoutDerivatives(EstimatedMeasurementBase<OneWayGNSSRangeRate> estimated)

Apply a modifier to an estimated measurement without derivatives.

Parameters:

estimated - estimated measurement to modify

dependsOnParticipantsStates

public boolean dependsOnParticipantsStates()

Description copied from interface: EstimationModifier

Method stating if the modifier requires for its computation the storage of the measurement's participants full dynamical states (position, velocity and acceleration) rather than just the date, the non-modified value, etc. Note that the SpacecraftState of the estimated trajectories (if applicable) can still be retrieved. The negative case shall be exploited for performance and is the default implementation.

Returns:
