ResumenThe lbergeov S geoid model was published in 1995, that was thefirst gravimetric geoid ofthe 1berian peninsula. From then on have appeared new geopotential models much more precise that those used then, 1have also had a new digital terrain model, new and precise data of gravity anomalies of Spain and of Portugal and altimetry sate/lite data in the marine areas. With all these new resources has been proceeded to calculate a new geoid 1BERGEO_2006 with the same methodology used in 1995 that demonstrated to be extremely usefu!. In this new geoid computation has been used the following data types: a) the Combined Gravity Field model E1GENCG03C complete to degree and order 360 from CHAMP, GRACE and surface gravity data, released on May 12, 2005 by GeoForschungsZentrum (GFZ) de Potsdam, b) a set of 209752 validated free air gravity anomalies covering the 1berian Peninsula and surrounding regions, e) a digital terrain model ofmesh side 200x200 meters, d) altimetry sate/lite data, and e) GPS data in levelling points provided by the Geographical lnstitutes of Spain and Portugal. The method used for the computations was the same of the lbergeov S: Stokes' integral. Ajier remove a Helmert correction, a collocation approach have been applied to obtain a reference surface for heights adjusted to GPS/Leveling points. The results have been compared with those obtained in 437 points resulting a standard deviation of 1.3 centimeters and a relative precision ofO.62 ppm.
