Dear Mr/Mrs Geodesy Engineer, Cartographers and AIS Specialists
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 standard for Vertical Reference System.
Question is raised regarding to Annex-15, 188.8.131.52:
....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. Instead, wWe are using the Baltic sea level value /1940-1970/ in Air Navigation.
My 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: ∆X, ∆ Y, ∆ Z, X rotation, Y rotation, Z rotation, Scale... etc. Is this correct?
