Re: [Orekit Developers] Earth Centered ICRF



Sounds good.  I'm not sure that I do.  What are we traditionally benchmarking our frame accuracies against?

Hello all,

Looking over the coordinate systems that are available, I can't figure out
a way to get an earth-centered (or for that matter central body centered)
ICRF coordinate system directly. I know I may just be overlooking
something.  If it isn't possible, would this be something that others would
be interested in having in the Orekit FramesFactory object?

If you have a use case for this, why not?
Adding predefined frames in FramesFactory is not costly as they are built only as needed, so we can add as much as we want.

By the way, if you have an accurate definition of what the old B1950 frame really is, this is also one frame that could be worth adding. There is a B1950-frame branch in the Git repository, but it was never sufficiently validated. It is also not in sync with master. If anybody want to give a look at it, they are welcome.

best regards,
Luc


Hank
