Constructor Details

AggregateBoundedAttitudeProvider

public AggregateBoundedAttitudeProvider(Collection<? extends BoundedAttitudeProvider> providers)

Constructor.

Parameters:

providers - attitude providers that provide the backing data for this instance. There must be at least one attitude provider in the collection. If there are gaps between the BoundedAttitudeProvider.getMaxDate() of one attitude provider and the BoundedAttitudeProvider.getMinDate() of the next attitude provider an exception may be thrown by any method of this class at any time. If there are overlaps between the the BoundedAttitudeProvider.getMaxDate() of one attitude provider and the BoundedAttitudeProvider.getMinDate() of the next attitude provider then the attitude provider with the latest BoundedAttitudeProvider.getMinDate() is used.

Method Details

getAttitude

public Attitude getAttitude(PVCoordinatesProvider pvProv,
 AbsoluteDate date,
 Frame frame)

Compute the attitude corresponding to an orbital state.

Specified by:

getAttitude in interface AttitudeProvider

Parameters:

pvProv - local position-velocity provider around current date

date - current date

frame - reference frame from which attitude is computed

Returns:

attitude on the specified date and position-velocity state

getAttitude

public <T extends CalculusFieldElement<T>>
FieldAttitude<T> getAttitude(FieldPVCoordinatesProvider<T> pvProv,
 FieldAbsoluteDate<T> date,
 Frame frame)

Compute the attitude corresponding to an orbital state.

Specified by:

getAttitude in interface AttitudeProvider

Type Parameters:

T - type of the field elements

Parameters:

pvProv - local position-velocity provider around current date

date - current date

frame - reference frame from which attitude is computed

Returns:

attitude on the specified date and position-velocity state

getAttitudeRotation

public Rotation getAttitudeRotation(PVCoordinatesProvider pvProv,
 AbsoluteDate date,
 Frame frame)

Compute the attitude-related rotation corresponding to an orbital state.

Specified by:

getAttitudeRotation in interface AttitudeProvider

Parameters:

pvProv - local position-velocity provider around current date

date - current date

frame - reference frame from which attitude is computed

Returns:

attitude-related rotation on the specified date and position-velocity state

getAttitudeRotation

public <T extends CalculusFieldElement<T>>
FieldRotation<T> getAttitudeRotation(FieldPVCoordinatesProvider<T> pvProv,
 FieldAbsoluteDate<T> date,
 Frame frame)

Compute the attitude-related rotation corresponding to an orbital state.

Specified by:

getAttitudeRotation in interface AttitudeProvider

Type Parameters:

T - type of the field elements

Parameters:

pvProv - local position-velocity provider around current date

date - current date

frame - reference frame from which attitude is computed

Returns:

rotation on the specified date and position-velocity state

getMinDate

public AbsoluteDate getMinDate()

Description copied from interface: BoundedAttitudeProvider

Get the first date of the range.

Specified by:

getMinDate in interface BoundedAttitudeProvider

Returns:

the first date of the range

getMaxDate

public AbsoluteDate getMaxDate()

Get the last date of the range.

Specified by:

getMaxDate in interface BoundedAttitudeProvider

Returns:

the last date of the range

getEventDetectors

public Stream<EventDetector> getEventDetectors()

Get the discrete events related to the model.

This method is not intended to be called several time, only once by a propagator, as it has the side effect of rebuilding the events detectors when called

Specified by:

getEventDetectors in interface AttitudeProvider

Specified by:

getEventDetectors in interface EventDetectorsProvider

Returns:

stream of event detectors

getFieldEventDetectors

public <T extends CalculusFieldElement<T>>
Stream<FieldEventDetector<T>> getFieldEventDetectors(Field<T> field)

Get the discrete events related to the model.

This method is not intended to be called several time, only once by a propagator, as it has the side effect of rebuilding the events detectors when called

Specified by:

getFieldEventDetectors in interface AttitudeProvider

Specified by:

getFieldEventDetectors in interface EventDetectorsProvider

Type Parameters:

T - extends CalculusFieldElement<T>

Parameters:

field - field to which the state belongs
