Evaluation of a double equipped MEMS IMU based on real flight trial scenarios

Abstract

The Inertial Measurement Unit (IMU) investigated within the presented work consists of two (optional three) dissimilar sets of MEMS accelerometers and gyros, respectively. Both sets are mounted in one enclosure and thus are subject to the same calibration procedure. Different combinations of these dual sensor sets can be used to exploit the complementary sensor properties, e.g. measurement range, resolution and noise characteristics as well as to benefit from redundancy in airborne applications.
