Constructor Detail

EstimatedMeasurementBase

public EstimatedMeasurementBase(T observedMeasurement,
                                int iteration,
                                int count,
                                SpacecraftState[] states,
                                TimeStampedPVCoordinates[] participants)

Simple constructor.

Parameters:

observedMeasurement - associated observed measurement

iteration - iteration number

count - evaluations counter

states - states of the spacecrafts

participants - coordinates of the participants in signal travel order in inertial frame of first state

Method Detail

getObservedMeasurement

public T getObservedMeasurement()

Get the associated observed measurement.

Returns:

associated observed measurement

getDate

public AbsoluteDate getDate()

Get the date.

Specified by:

getDate in interface TimeStamped

Returns:

date attached to the object

getIteration

public int getIteration()

Get the iteration number.

Returns:

iteration number

getCount

public int getCount()

Get the evaluations counter.

Returns:

evaluations counter

getStates

public SpacecraftState[] getStates()

Get the states of the spacecrafts.

Returns:

states of the spacecrafts

getParticipants

public TimeStampedPVCoordinates[] getParticipants()

Get the coordinates of the measurements participants in signal travel order.

First participant (at index 0) emits the signal (it is for example a ground station for two-way range measurement). Last participant receives the signal (it is also the ground station for two-way range measurement, but a few milliseconds later). Intermediate participants relfect the signal (it is the spacecraft for two-way range measurement).

Returns:

coordinates of the measurements participants in signal travel order in inertial frame of first state

getTimeOffset

public double getTimeOffset()

Get the time offset from first state date to measurement date.

Returns:

time offset from first state date to measurement date

getObservedValue

public double[] getObservedValue()

Get the observed value.

The observed value is the value that was measured by the instrument.

Specified by:

getObservedValue in interface ComparableMeasurement

Returns:

observed value

setObservedValue

public void setObservedValue(double[] observed)

Set the observed value.

The observed value is the value that was measured by the instrument.

Specified by:

setObservedValue in interface ComparableMeasurement

Parameters:

observed - observed value

getOriginalEstimatedValue

public double[] getOriginalEstimatedValue()

Get the original estimated value prior to any modification.

Returns:

original estimated value prior to any modification

Since:

12.1

getAppliedEffects

public IdentityHashMap<EstimationModifier<T>,double[]> getAppliedEffects()

Get the applied effects of modifiers.

The effects have already accounted for in getEstimatedValue()

Returns:

applied modifier effects

Since:

12.1

getEstimatedValue

public double[] getEstimatedValue()

Get the estimated value.

Returns:

estimated value

setEstimatedValue

public void setEstimatedValue(double... estimatedValue)

Set the estimated value.

Parameters:

estimatedValue - estimated value

See Also:

modifyEstimatedValue(EstimationModifier, double...)

modifyEstimatedValue

public void modifyEstimatedValue(EstimationModifier<T> modifier,
                                 double... newEstimatedValue)

Modify the estimated value.

Parameters:

modifier - modifier that generates this estimated value

newEstimatedValue - new estimated value

Since:

12.1

getStatus

public EstimatedMeasurementBase.Status getStatus()

Get the status.

The status is set to PROCESSED at construction, and can be reset to REJECTED later on, typically by OutlierFilter or DynamicOutlierFilter

Returns:

status

setStatus

public void setStatus(EstimatedMeasurementBase.Status status)

Set the status.

Parameters:

status - status to set
