Discover Tronics GYPRO®4300, a high stability and vibration-tolerant digital MEMS gyro for mining and oil & gas applications. Housed in a miniature ceramic package, it features a bias instability of 0.4 °/h and a vibration rectification error of 0.5 °/h/g², which make it a digital and low-SWaP alternative to Fiber Optic Gyros for directional drilling guidance and survey applications.

Precise guidance and orientation in mining and oil and gas applications

GYPRO4300 is the first product in Tronics GYPRO4000 MEMS gyro series. With an excellent bias instability of 0.5 °/h and an ARW (Angular Random Walk) of 0.1 °/√h, GYPRO4300 is a miniature, high-stability digital MEMS gyro for precise guidance and orientation of directional drilling and survey instruments.

Miniature and robust gyro for drilling and survey instruments operating under harsh conditions

The closed-loop architecture of GYPRO4300 allows to achieve a strong vibration rejection of 0.5 °/h/g² under harsh vibrating conditions. GYPRO4300 gyro is housed in a miniature and hermetic J-lead package that ensures long operational and storage life. Its small form-factor allows to build compact multi-axis inertial systems that fit into a low-diameter cylinder. To minimize mechanical cross-coupling effects, GYPRO4300 is available in 3 frequency ranges.

Low-SWaP, cost-effective and high reliability gyroscope

Thanks to its miniature package and low-power consumption, Tronics GYPRO4300 gyro offers a digital, cost-effective, and low-SWaP alternative to bulky, expensive, and power-consuming solutions like DTG (Dynamically Tuned Gyros) and FOG (Fiber Optical Gyroscopes). With its solid-state architecture that reduces the number of components and system complexity, GYPRO4300 exhibits a MTBF higher than 1,000,000 hours, more than 10 times better than DTG and FOG with similar performances. The built-in self-test ensures both an initial verification of the sensor’s integrity and a continuous in-operation functionality test.
