AUVSI’s Unmanned Systems: Mission Critical magazine published an article on MEMs (microelectromechanical) devices used in today’s world. The author highlights MEMs sensors used in unmanned systems, specifically those produced by Xsens. Xsens is a leader in IMU (inertial measurement units), ADHRS (attitude and heading reference systems), and INS (inertial navigation systems), which is used in Area-I’s PTERA UAS. The article can be found in the Winter 2012 magazine.
