I Have a problem:
There are Greenwich coordinates (ECEF),$$\eta_1=2850144.282468, \eta_2=2197962.005840, \eta_3=5248530.328116.$$
Calculate the values of geographical coordinates (Geodetic), for these coordinates.
I can't find any information about relationship between these system of coordinates and literature where I can read about this. It would be great if you helped me, because I've lost a lot time to find useful information,
Thanks for the help!
