Abstract
Recently, there is an increased interest in studying and defining the Local and Regional Geoid Model worldwide, due to its importance in geodetic and geophysics applications.
The use of the Global Positioning System (GPS) is internationally growing, yet the lack of any Geoid Model for Jordan has limited the use of GPS for geodetic applications. Therefore, this work aims to present the preliminary results that we propose for The Gravimetric Jordanian Geoid Model (GeoJordan). The model is created using gravimetric data and the GravSoft program. The validation of this model is done by using GPS measurements and precise leveling at Amman area.
However, a comparison between the Global Geopotential Models OSU91A and EGM96 showed great discrepancies through the presented results. Also, presenting the approach used to obtain the orthometric height from GPS ellipsoidal height measurements. Nevertheless, the error margin; obtained in this initial study of the GeoJordan after fitting the data with GPS/leveling measurement; is about (10cm), in tested area whereas the standard error of the created model is about (40cm).
