HRG by Sagem from laboratory to mass production

Abstract

For more than two decades, Sagem has built up its expertise through different developments and applications of CVG (Coriolis Vibrating Gyros). One example is the well-known HRG (Hemispherical Resonator Gyroscope). This paper shows the large panel of applications covered with HRG, in a nominal configuration system and in a redundant inertial skewed system. We also evoke the ultimate performance application obtained with specific system configuration, thanks to the remarkable properties of the HRG. In the end, we describe the industrial aspects deployed to address all these applications.
