Method Detail

getEOPHistory

EOPHistory getEOPHistory()

Get the EOP history.

Returns:

EOP history

getNonInterpolatingProvider

EOPBasedTransformProvider getNonInterpolatingProvider()
                                               throws OrekitException

Get a version of the provider that does not cache tidal corrections.

This method removes the performance enhancing interpolation features that are used by default in EOP-based provider, in order to focus on accuracy. The interpolation features are intended to save processing time by avoiding doing tidal correction evaluation at each time step and caching some results. This method can be used to avoid this (it is automatically called by FramesFactory.getNonInterpolatingTransform(Frame, Frame, AbsoluteDate), when very high accuracy is desired, or for testing purposes. It should be used with care, as doing the full computation is really costly.

Returns:

version of the provider that does not cache tidal corrections

Throws:

OrekitException - if EOP cannot be retrieved
