3-axis Rate Gyro (VSG-based)

The silicon micro-machined ring gyroscope was designed to provide high performance under harsh environmental conditions, the device uses a silicon vibrating structure gyro angular rate sensor. Originally, they were made at BAE's Inertial Products Division, located in Plymouth, UK, which was bought out and became Atlantic Inertial Systems in 2007 (and then became several others including UTC due to various buy outs); it is now part of Collins Aerospace. (UTC Aerospace Systems won a 2013 Queen’s Award for Enterprise, in the category of Innovation, which recognised the international success of the business’ unique, miniature, solid state gyroscopic devices). All of them seem to be initial runs or prototypes of current products. These rugged inertial measurement units (IMUs) help guide a wide variety of systems including air and land vehicles, missiles and shells.
