Research & Development (R&D)

GRAVIONIC is a spin-off of the Institute of Flight Guidance and Control (IFF) of the Technical University of Braunschweig/Germany. Due to this special background, our team has unique skills in the analysis, modelling and modification of dynamic systems (sensors, vehicles, aircraft, etc.) and also in special precise GNSS/INS positioning and navigation. In result we team up with the following background: aerospace engineering, mechanical engineering, electrical engineering, physical and satellite geodesy, geophysics, navigation and positioning, flight control and mechanics, geology and also biology. As we are generally specialized in the development of complex sensor systems, into the past years we developed the marine and airborne gravity system iCAGS. This system is also suitable for vehicle born gravity and for operation on small and fast boats.

Furthermore we developed special test procedures and test benches to verify the quality of airborne gravity sensors.
