public interface AttitudeProvider
extends Serializable

This interface represents an attitude provider model set.

An attitude provider provides a way to compute an Attitude from an date and position-velocity local provider.

Method Summary

Attitude	getAttitude(Orbit orbit) Compute the attitude corresponding to an orbital state.
Attitude	getAttitude(PVCoordinatesProvider pvProv, AbsoluteDate date, Frame frame) Compute the attitude corresponding to an orbital state.
void	setSpinDerivativesComputation(boolean computeSpinDerivatives) Method to activate spin derivative computation.

Method Detail

getAttitude

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

Compute the attitude corresponding to an orbital state.

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:

OrekitException - if attitude cannot be computed

getAttitude

Attitude getAttitude(Orbit orbit)
                     throws OrekitException

Compute the attitude corresponding to an orbital state.

Parameters:

orbit - current orbit

Returns:

attitude attitude on the current orbit

Throws:

OrekitException - if attitude cannot be computed

setSpinDerivativesComputation

void setSpinDerivativesComputation(boolean computeSpinDerivatives)
                                   throws OrekitException

Method to activate spin derivative computation.

Parameters:

computeSpinDerivatives - true if spin derivatives should be computed

Throws:

OrekitException - if spin derivatives can not be computed
