Method Detail

getAttitude

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

Compute the attitude corresponding to an orbital state.

Specified by:

getAttitude in interface AttitudeProvider

Overrides:

getAttitude in class StrictAttitudeLegsSequence<AngularVelocitiesPolynomialProfileLeg>

Parameters:

pvProv - local position-velocity provider around current date

date - current date

frame - reference frame from which attitude is computed

Returns:

attitude attitude on the specified date and position-velocity state

Throws:

PatriusException - if attitude cannot be computed for provided date

setSpinDerivativesComputation

public void setSpinDerivativesComputation(boolean computeSpinDerivatives)

Method to activate spin derivative computation.

Specified by:

setSpinDerivativesComputation in interface AttitudeProvider

Overrides:

setSpinDerivativesComputation in class StrictAttitudeLegsSequence<AngularVelocitiesPolynomialProfileLeg>

Parameters:

computeSpinDerivatives - true if spin derivatives should be computed

getXCoefficients

public Map<AbsoluteDateInterval,double[]> getXCoefficients()

Returns:

the map containing the coefficients of the polynomial function representing x, and their time interval of validity.

getYCoefficients

public Map<AbsoluteDateInterval,double[]> getYCoefficients()

Returns:

the map containing the coefficients of the polynomial function representing y, and their time interval of validity.

getZCoefficients

public Map<AbsoluteDateInterval,double[]> getZCoefficients()

Returns:

the map containing the coefficients of the polynomial function representing z, and their time interval of validity.

getNature

public String getNature()

Returns the nature of the leg.

Specified by:

getNature in interface Leg

Returns:

The “nature” of the leg.

copy

public AngularVelocitiesPolynomialProfile copy(AbsoluteDateInterval newInterval)

Creates a new leg from this one.

Specified by:

copy in interface Leg

Parameters:

newInterval - The time interval of the leg to create

Returns:

A new Leg valid on provided interval

toPrettyString

public String toPrettyString()

Returns a nice String representation.

Specified by:

toPrettyString in interface Leg

toPrettyString in interface LegsSequence<AngularVelocitiesPolynomialProfileLeg>

Specified by:

toPrettyString in interface TimeSequence<AngularVelocitiesPolynomialProfileLeg>

Returns:

A nice String representation.

getTimeInterval

public AbsoluteDateInterval getTimeInterval()

Returns the time interval of the legs sequence.

Null is returned if the sequence is empty.

Warning: in case of sequences with holes, the sequence in the returned interval will not contain continuous data.

Sequence is supposed to be continuous.

Specified by:

getTimeInterval in interface Leg

Specified by:

getTimeInterval in interface LegsSequence<AngularVelocitiesPolynomialProfileLeg>

Overrides:

getTimeInterval in class StrictLegsSequence<AngularVelocitiesPolynomialProfileLeg>
