In Gps (Topcon GR3) i have this message:
Greek HEPOS grid files are needed for this calculation. Please go to the Carlson Software Knowledge Base to obtain the needed files.
I cannot find the solution for this problem.
I had to create a Geoid File with Carlson Xport for SurvCE?
I resolved the problem very quickly with the help of the Technical Support, Carlson EMEA
Thank you very much !
