MEMS gyro for motion control and positioning

High performance ± 300 °/s MEMS gyroscope with digital interface

High bias stability for precision navigation and positioning in dynamic applications

GYPRO®4300 is a high-performance, closed-loop digital MEMS gyroscope with ± 300 °/s input range 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 GNSS and sensor-fusion precise positioning, navigation, stabilization functions in dynamic applications such as railway, land vehicles, VTOL (Vertical Take-Off and Landing) aircraft and UAV (Unmanned Aerial Vehicles), and marine systems.

The hermetic ceramic SMD package combined with a 24 bits SPI interface eases the integration of GYPRO®4300 and reduces the BOM. The built-in self-test ensures initial verification of the sensor’s integrity and continuous in-operation functionality test.
