Re: [Orekit Users] Question about Frames



EME2000 is the J2000 frame and ITRF is the ECEF and you want to use the 2010 IERS.  The code you would use to initialize the the ITRF/ECEF frame would be:

FramesFactory.getITRF(IERSConventions.IERS_2010, true);

Hi,

I have ECEF data I would like to convert to J2000. I have read the docs and I know how to transform, but I don't know what to use as the source frame. Is ITRF the same or very close? And if so how do I determine which of the many ITRF configurations is most appropriate for the data I have?

Thanks,
Zach
