Abstract
An airborne geoid mapping system is in development within the AGMASCO Project. The goal is the establishment of a system to be used mainly for regional, near coastal seasurface topography determination by combining airborne gravity, airborne altimetry, DGPS and INS. Such a system can complimentary solve the problems of geoid modelling and sea-surface topography determination, bridging the gap between land areas and open ocean. It is therefore well suited for coastal and island areas. The reliability of the system is proven by using quasi-simultaneously ground truth shipborne gravity, ADCP and CTD measurements, and comparisons with satellite altimetry data.
The AGMASCO system, consisting of a laser and radar altimeter, a gravimeter, two GPS receivers, an INS and a data logging unit, was used in September 1996 to survey the Skagerrak sea area. Quasi simultaneous shipborne measurements were carried out by M/S Haakon Mosby, the research vessel owned by the University of Bergen.
In the paper we describe the system used in this campaign, present the methodology adopted for data processing and discuss the results achieved. The campaign in the Azores region is scheduled for October 1997. Details of the installation of the system, in a CASA C212 aircraft of the Portuguese Air Force, for this campaign will also be presented.
