Or do I need to transform ECEF coordinates in the NTRIP client?Why do I need to "map into the LLH domain, then map back into ECEF in the WGS84 frame"? Did you mean LLH(ETRS2000)->ECEF(ETRS2000)->ECEF(ITRF2014)? Why not ETCF (ETRS2000) -> ETEF(ITRF2014) directly if 1005 comes in ECEF format?On How to avoid position bias/shift when the rover connects to the base station (EPN – EUREF network)?Crop
