Constructor Details

PhaseCentersRangeModifier

public PhaseCentersRangeModifier(FrequencyPattern stationPattern,
 FrequencyPattern satellitePattern)

Simple constructor.

Parameters:

stationPattern - station pattern

satellitePattern - satellite pattern

Method Details

getParametersDrivers

public List<ParameterDriver> getParametersDrivers()

Get the drivers for parameters.

Specified by:

getParametersDrivers in interface ParameterDriversProvider

Returns:

drivers for parameters

getObserver

public Observer getObserver(EstimatedMeasurementBase<Range> estimated)

Retrieve observer.

Specified by:

getObserver in class PhaseCentersGroundReceiverBaseModifier<Range>

Parameters:

estimated - estimated measurement to modify

Returns:

observer associated with measurement

modifyWithoutDerivatives

public void modifyWithoutDerivatives(EstimatedMeasurementBase<Range> estimated)

Apply a modifier to an estimated measurement without derivatives.

Specified by:

modifyWithoutDerivatives in interface EstimationModifier<Range>

Parameters:

estimated - estimated measurement to modify

dependsOnParticipantsStates

public boolean dependsOnParticipantsStates()

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 the date, the non-modified value, etc. The negative case shall be exploited for performance and is the default implementation.

Specified by:

dependsOnParticipantsStates in interface EstimationModifier<Range>

Returns:

dependence flag
