Proposed IEEE Coriolis Vibratory Gyro standard and other inertial sensor standards

A new Coriolis Vibratory Gyro (CVG) Specification Format Guide and Test Procedure is being developed by the IEEE/AESS Gyro and Accelerometer Panel for consideration by the IEEE Standards Association as IEEE Std. 1431. It provides guides for specifying CVG performance and gives test procedures for verifying compliance with requirements. It also describes the various types of CVG, ranging from vibrating shell macro-sized devices to low-cost silicon and quartz chip micro-sized devices. Model equations are given for the various CVG operating and readout modes: whole-angle, open-loop, force-rebalance, and ratiometric. Also discussed in this paper are the IEEE standards that have been published for single- and two-degree-of-freedom spinning wheel gyros, laser gyros, interferometric fiber optic gyros, angular accelerometers, linear accelerometers, accelerometer centrifuge testing, and inertial sensor terminology, and an inertial sensor test equipment and analysis document and an inertial systems terminology document that are under development.
