[Termes IGN] positionnement par GNSSRésumé : (Auteur) The official Croatian geoid model HRG2000 was developed as a surface for con--version of GNSS-derived ellipsoidal heights into orthometric heights. CROatian POsitionig System (CROPOS), based on 30 permanently working GNSS reference station, had been esta-blished last year. Since HRG2000 geoid model characterizes some weaknesses regarding abso-lute orientation we have used CROPOS service to define new points which will be a base for creation of the new Croatian geiod model HRG2009. For this purpose over the whole Croatian territory more than 500 GNSS/levelling geodetic points were stabilized and measured according to the approximate raster of10x10km. All measured points were connected to the nearest ben-chmarks of the new Croatian vertical datum by precise levelling. The GNSS/Levelling survey provides reliable geoid undulation but only at the points where the survey is made. Therefore for the construction of an accurate HRG2009 geoid model afterwards the gravimetric geo-id model, which should be calculated from all new measured gravity points and old availa-ble gravity data, will befitted to the geoid undulation data from a GNSS/levelling survey. The recently determined geoid undulation calculated from GNSS/Levelling data at the measured geodetic points were analyzed additionally in relation to the geoid undulation from the geoid model HRG2000. The range of geoid undulation and orthometric height differences at measu-red points between old and new geoid model shows an important progress concerning quality in definition of heights for the Republic of Croatia.

[Termes IGN] quasi-géoïdeRésumé : (auteur) The archipelago of New Caledonia is located in the Pacific Ocean, near the New Hebrides Trench. The gravity field is extremely rough in this area, free-air gravity anomalies varying from –230 to +200 mgal. Two vain attempts to compute a geoid model in 2000 and 2004 led the Territorial Government of New Caledonia to put IGN (French National Geographic Institute) in charge of a new calculation. Gravity data were provided by several institutions (Bureau Gravimétrique International, Institut de Recherches pour le Développement, Genavire, IGN) and were of various quality, so that data cleaning has been an important stage. Using the GRAVSOFT package, height anomalies have been computed by the residual terrain method combined with Stokes integration. By comparison of the quasi-geoid with levelled GPS points on the main island, accuracy has been estimated to be better than 9 cm, which shows a significant improvement with previous solutions. A grid to convert ellipsoidal heights into heights above mean sea level has been derived from the quasi-geoid and levelled GPS points. Its accuracy is about 4.5 cm. The shifts between vertical reference systems of principal islands of the archipelago have been determined. Differences between the geoid and the mean sea level at tide gauges, and their correlation with oceanic currents have also been studied and discussed in the paper.
