Minitact gyroscope-the low cost alternative

The allure of the solid state optical gyros is being challenged by the invention of a new spinning mass device providing superior low noise drift performance, high reliability at a very low cost. The Minitact is a unique two axis gyroscope advancing the technology of spinning mass devices to set new low cost standards. Minitact provides all the low noise performance benefits of tuned rotor gyroscopes without the vagaries of flexure suspension systems. The Minitact design integrates together the advantages of a spherical hydrodynamic gas bearing and a three axis permanent magnet DC commutated motor and torquer, into a miniature two axis gyroscope with a dynamic range of greater than 10⁷. The design is described and performance data presented illustrating the capability of this low cost next generation rate gyroscope. The Minitact is the result of integrated product development (IPD) and design to unit production cost (DTUPC) design processes and is expected to become the tactical performance benchmark
