Method Summary

Modifier and Type	Method	Description
void	addModifier(EstimationModifier<T> modifier)	Add a modifier.
T	build(AbsoluteDate date, Map<ObservableSatellite,OrekitStepInterpolator> interpolators)	Generate a single measurement.
default T	build(AbsoluteDate date, SpacecraftState[] states)	Generate a single measurement.
List<EstimationModifier<T>>	getModifiers()	Get the modifiers that apply to a measurement.

Method Detail

init

void init(AbsoluteDate start,
          AbsoluteDate end)

Initialize builder at the start of a measurements generation.

This method is called once at the start of the measurements generation. It may be used by the builder to initialize some internal data if needed, typically setting up parameters reference dates.

Parameters:

start - start of the measurements time span

end - end of the measurements time span

addModifier

void addModifier(EstimationModifier<T> modifier)

Add a modifier.

Parameters:

modifier - modifier to add

getModifiers

List<EstimationModifier<T>> getModifiers()

Get the modifiers that apply to a measurement.

Returns:

modifiers that apply to a measurement

See Also:

addModifier(EstimationModifier)

getSatellites

ObservableSatellite[] getSatellites()

Get the satellites related to this measurement.

Returns:

satellites related to this measurement

Since:

12.0

build

T build(AbsoluteDate date,
        Map<ObservableSatellite,OrekitStepInterpolator> interpolators)

Generate a single measurement.

Parameters:

date - measurement date

interpolators - interpolators relevant for this builder

Returns:

generated measurement

Since:

12.0

build

default T build(AbsoluteDate date,
                SpacecraftState[] states)

Generate a single measurement.

Warning: This method uses "shiftedBy" so it is not as accurate as the method above that uses interpolators.

Parameters:

date - measurement date

states - all spacecraft states (i.e. including ones that may not be relevant for the current builder)

Returns:

generated measurement
