High stability digital MEMS gyro
Low ARW, high accuracy and high repeatability MEMS gyroscope
High precision ± 300 °/s closed-loop MEMS gyroscope with digital interface
High bias stability & vibration tolerant angular rate MEMS gyro
GYPRO®4300 is a miniature, tactical-grade, low ARW and low drift digital MEMS gyroscope 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.
It features a ± 300 °/s input measurement range, 200 Hz bandwidth and 1 ms latency with a closed-loop architecture that ensures high linearity and stability in dynamic environments.
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 precision MEMS gyro that paves the way to a new generation of precise positioning, navigation, and stabilization functions in dynamic applications such as railway, land vehicles, VTOL (Vertical Take-Off and Landing) aircraft and UAV (Unmanned Aerial Vehicles), marine and subsea systems, borehole drilling and surveying instruments.
Precision MEMS gyro
Due to its solid-state architecture that reduces the number of internal components and system complexity, GYPRO®4300 high precision gyro demonstrates a MTBF higher than 1,000,000 hours, more than 10 times better than incumbent DTG and FOG with similar performances.
In addition, its built-in self-test ensures both an initial verification of the sensor’s integrity and a continuous in-operation functionality test.
