GYPRO®4300
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.
Its high bias stability and vibration rejection make GYPRO®4300 an industry-leading MEMS sensor to build high-performance IMU (Inertial Measurement Units) for attitude and motion control systems, as well as INS (Inertial Navigation Systems) for GNSS-aided positioning and navigation 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.
