Constructor Details

AngularRaDecBuilder

public AngularRaDecBuilder(GroundStation station,
 Frame referenceFrame,
 double[] sigma,
 double[] baseWeight,
 ObservableSatellite satellite)

Simple constructor.

Parameters:

station - ground station from which measurement is performed

referenceFrame - Reference frame in which the right ascension - declination angles are given

sigma - theoretical standard deviation

baseWeight - base weight

satellite - satellite related to this builder

AngularRaDecBuilder

public AngularRaDecBuilder(Observer observer,
 Frame referenceFrame,
 MeasurementQuality measurementQuality,
 SignalTravelTimeModel signalTravelTimeModel,
 ObservableSatellite satellite)

Simple constructor.

Parameters:

observer - sensor from which measurement is performed

referenceFrame - Reference frame in which the right ascension - declination angles are given

measurementQuality - measurement quality as used in estimation (in Orekit, the crossed-terms of the covariance matrix are only used by Kalman filters, not least squares)

signalTravelTimeModel - signal travel time model

satellite - satellite related to this builder

Since:

14.0

Method Details

getObserver

public Observer getObserver()

Getter for the observer.

Returns:

observer

Since:

14.0

buildObserved

protected AngularRaDec buildObserved(AbsoluteDate date,
 Map<ObservableSatellite,OrekitStepInterpolator> interpolators)

Build a dummy observed measurement.

Specified by:

buildObserved in class AbstractMeasurementBuilder<AngularRaDec>

Parameters:

date - measurement date

interpolators - interpolators relevant for this builder

Returns:

dummy observed measurement
