GYPRO®4300
High Stability ± 300 °/s digital MEMS Gyro
High stability and repeatability for navigation in severe temperature and vibrations conditions
GYPRO®4300 is a high-performance, closed-loop digital MEMS gyroscope with ± 300 °/s input range that offers a cost-effective alternative to Fiber-Optic Gyroscopes (FOG) at a fraction of their size, weight, and power consumption.
With an excellent bias instability of 0.4 °/h and an ARW (Angular Random Walk) of 0.07 °/√h, GYPRO4300 offers a miniature, digital and low-SWaP (Size, Weight and Power) high performance MEMS rate gyro that paves the way to a new generation of precise positioning, navigation, and stabilization functions in dynamic applications.
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.
MEMS gyros for navigation of dynamic applications
GYPRO®4300 is a high stability MEMS gyro tailored to GNSS-assisted inertial navigation and positioning of ground vehicles and trains, MRU (Motion Control Unit) for ship motion control and positioning, as well as AHRS for small aircrafts, helicopters, and drones.
In addition, it is a perfect candidate for integration into Inertial Measurement Units (IMU) used for guidance and orientation of directional drilling and survey instruments. Its miniature package allows to build high precision inertial systems exhibiting a compact form-factor that fits into a low diameter tube.
