GYPRO®4300

Excellent repeatability and stability for navigation in extreme environments

With a ± 300 °/s input range, the high-performance, closed-loop digital MEMS gyroscope, GYPRO®4300 provides a viable substitute for Fiber-Optic Gyroscopes (FOG) at a fraction of the size, weight, and power consumption.

It has an excellent bias instability of 0.4 °/h and an ARW (Angular Random Walk) of 0.07 °/√h. This paves the way for a new generation of precise positioning, navigation, and stabilization functions in dynamic applications.

The 24 bits SPI interface and hermetic ceramic SMD package make it easier to integrate the GYPRO4300 and lower the BOM. Initial sensor integrity verification and ongoing in-operation functionality testing are guaranteed by the integrated self-test

Tailored to dynamic applications

Our high stability gyro is designed for GNSS-assisted inertial navigation and positioning of ground vehicles and trains, MRU (Motion Control Unit) for ship motion control and positioning, and AHRS for light aircrafts, helicopters, and drones.

Furthermore, it is an ideal option for incorporation into directional modules which are employed in survey and directional drilling tools. Because of its small size, it is possible to construct very accurate inertial systems with a small form factor that can be contained in a small diameter tube.
