Xsens, a supplier of 3D motion tracking systems, signed an agreement today with Sagem (Safran Group) for the supply of advanced sensor fusion signal processing modules for integration in a new line of inertial system products from Sagem. Sagem chose Xsens after a careful technology and supplier selection process. As part of the supply agreement, Xsens has customized its proven 3D motion tracking sensor fusion algorithms to take full benefit of Sagem’s advanced Coriolis resonating gyros and high grade silicon accelerometers. Building on the XKF-3™ sensor fusion algorithms for 3D orientation estimation, Xsens is delivering a custom DSP module which outputs very accurate vertical reference values, even in dynamic situations.
