Abstract:	This paper will describe the cooperative tests executed by both naval offices NAVOCEANO and DHN in order to evaluate the seabed mapping in an earth centered earth fixed (ECEF) geocentric reference frame. The field experimentation was performed in Guanabara Bay, Rio de Janeiro, from 06 to 17 July 2009. Data collection included GPS surveys at six tide stations locations, hydrodynamic modeling, water level measurements, local datum computation using different software packages and ECEF bathymetric surveys. Data processing using both traditional method with local tide gauge measurements and ECEF method with tidal information extracted from GPS and hydrodynamic computations allowed a comparison of results, which are presented in the paper. This joint survey allowed both institutions to validate ECEF survey techniques that can potentially be utilized in areas where in-situ data do not exist or are difficult to obtain. Also permitted that Brazilian Geoidal model MAPGEO2010 could be tested for ECEF surveys applications.
