Method Details

getUnderlyingAttitudeProvider

AttitudeProvider getUnderlyingAttitudeProvider()

Get the underlying attitude provider.

Returns:

underlying attitude provider

getAttitude

default 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

default <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

getEventDetectors

default Stream<EventDetector> getEventDetectors(List<ParameterDriver> parameterDrivers)

Get the discrete events related to the model from a list of ParameterDriver

Date detectors are used to cleanly stop the propagator and reset the state derivatives at transition dates (if any) of the parameter drivers.

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

Specified by:

getEventDetectors in interface EventDetectorsProvider

Parameters:

parameterDrivers - list of parameter drivers

Returns:

stream of event detectors

getFieldEventDetectors

default <T extends CalculusFieldElement<T>>
Stream<FieldEventDetector<T>> getFieldEventDetectors(Field<T> field,
 List<ParameterDriver> parameterDrivers)

Get the discrete events related to the model from a list of ParameterDriver

Date detectors are used to cleanly stop the propagator and reset the state derivatives at transition dates (if any) of the parameter drivers.

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

Specified by:

getFieldEventDetectors in interface EventDetectorsProvider

Type Parameters:

T - extends CalculusFieldElement<T>

Parameters:

field - field to which the state belongs

parameterDrivers - list of parameter drivers

Returns:

stream of event detectors

getParametersDrivers

default List<ParameterDriver> getParametersDrivers()

Get the drivers for parameters.

Specified by:

getParametersDrivers in interface AttitudeProvider

Specified by:

getParametersDrivers in interface ParameterDriversProvider

Returns:

drivers for parameters

getFrozenAttitudeProvider

static AttitudeProviderModifier getFrozenAttitudeProvider(AttitudeProvider attitudeProvider)

Wrap the input provider with a new one always returning attitudes with zero rotation rate and acceleration. It is not physically sound, but remains useful for performance when a full, physical attitude with time derivatives is not needed.

Parameters:

attitudeProvider - provider to wrap

Returns:

wrapping provider
