Dear Mr/Mrs Geodesy Engineers
I have a quite deep question here,
AIP data locations are determined by geographic coordinates /X & Y axis/ and vertical values /Z axis/ via Geodesy science.
ICAO adopted EGM-96 is standard for Vertical Reference System.
Question is raised regarding to Annex-15, 126.96.36.199 "......When a geoid model other than the EGM-96 model is used, a description of the model used, including the parameters required for height transformation between the model and EGM-96, shall be provided in the Aeronautical Information Publication (AIP)."
In Mongolia, We are not using EGM-96 for Vertical Reference System. We are using Baltic sea level value /1940-1970/ in Air Navigation.
Question is: How to figure out the parameters required for height transformation between any model and EGM-96 for AIP publication?
In my thinking the parameters must contain following values: delta X, delta Y, delta Z, X rotation, Y rotation, Z rotation, Scale... etc. Is this correct?
