Geoid models are always an essential tool to take advantage of GNSS 3D positioning to produce orthometric heights. Cartographic products and applications continue to grow in detail and now its vertical control is completely reliant on GNSS surveys. It is in this environment that the national cartographic agency in Mexico (INEGI) works in collaboration with the University of New Brunswick to renew the official geoid model. In this work we present the model xGGM23, a gravimetric solution with significant improvements in relation to its predecessor GGM10, mostly due to advances in the modeling technique and the inclusion of better gravity data coverage. The solution was achieved implementing the UNB’s Stokes-Helmert technique, combining terrestrial gravimetry with the geopotential model GOCO06s. The initial analysis of difference between modeled geoidal heights and GNSS/leveling suggest that the accuracy of xGGM23 is 10 cm. This model represents additionally a contribution to the international efforts to generate a regional geoid model for North and Central America.
