Hi, I would like to add the Philippine Geoid Model 2018 to Trimble MX and into your knowledge base (https://kb.orbitgt.com/261/technology/core/crs). I don't think there's an EPSG code for it. Her's a link to download a .7z file containing two files:

• geoid2018.98_wgsfit.xyz: the geoid model fitted with WGS84.

• geoid2018.98_itrffit.xyz: the geoid model fitted with ITRF.

My customer would like to have both integrated in the software and, least importantly, in the KB.

Detailed information about the geoid can be found here. The geoid's .ggf and .gri files can be downloaded here.
