Ephemeris data in Emlid Studio

I am new and I have a question regarding these corrections, I had understood that to correct it was necessary to read the emlid, CORS data and NASA ephemerides. In the Emlid Studio it only asks for the EMLID data and the CORS data, in the Emlid Studio result I got 2mm of error (the reading was 7 hours).

Hi,

Welcome to our community forum!

Not sure I understand you correctly, but Emlid Studio requires a navigation file to post-process the logs. Ephemeris is part of the navigation file respectively. How did you manage to post-process without it? Perhaps you took it from the CORS data?

Do you the Precise Orbit+Clock data, that they provide?
If you literally mean Ephemeris, then the .nav / .22n file from Emlid data is perfectly fine to use.
