ParameterDriver : several estimated values on several dates / time intervals
In order to be able to estimate EOP and do more precise orbit determination it would be very interesting to be able to estimate precisely EOP. Something about it already exist in Orekit in the Ground Station class but it is done in a clumsy and not very rigorous way. It might be better to estimate EOP at frame level by creating a new provider EstimatedITRFProvider.
A preliminary step is necessary : ParameterDriver should be able to have several estimated values on several interval or at several dates, which is not implemented for now. ParameterDriver could have a value TimeSpanMap as attribute (instead of a simple double value) and a name TimeSpanMap (cut accordingly to the value TimeSpanMap to keep coherence (same intervals/date)) to be able to keep the actual orbit determination process (Jacobian columns naming process…).
A discussion has been opened about it here : https://forum.orekit.org/t/parameterdriver-with-timespanmap-value-for-futur-eop-estimation/1949
