Constructor Detail

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 Detail

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 attitude on the specified date and position-velocity state

getAttitude
