GYPRO®4300: High performance ± 300 °/s MEMS gyroscope with digital interface

GYPRO4300 HIGH PERFORMANCE DIGITAL MEMS GYRO

High bias stability for precision positioning and navigation in dynamic aerospace applications

GYPRO®4300 is a high-performance, closed-loop digital MEMS gyroscope with ± 300 °/s input range and 200 Hz that offers a cost-effective alternative to entry-level Fiber Optic Gyroscopes (FOG) and Dynamically Tuned Gyroscopes (DTG) at a fraction of their size, weight, and power consumption.

With an excellent bias instability of 0.4°/h as typical value (2°/h maximum) and an Angular Random Walk (ARW) of 0.07 °/√h, GYPRO®4300 brings to the market a miniature, digital and low-SWaP (Size, Weight and Power) high performance MEMS gyro that paves the way to a new generation of precise positioning, navigation, and stabilization functions in dynamic applications such as VTOL (Vertical Take-Off and Landing) aircraft and UAV (Unmanned Aerial Vehicles).
