TDK RELEASES GYPRO^®4300 HIGH STABILITY DIGITAL MEMS GYRO FOR DYNAMIC APPLICATIONS

TDK Corporation has released Tronics GYPRO^®4300, a high-stability and vibration-tolerant digital MEMS gyroscope for dynamic applications. This gyro 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. The GYPRO4300 is the first product reference of Tronics GYPRO4000's new high-performance digital MEMS gyro platform which complements the recently announced AXO300 closed-loop digital accelerometers platform.

Precise navigation and positioning in dynamic applications
With an excellent bias instability of 0.5 °/h as a typical value (2 °/h maximum) and an ARW (Angular Random Walk) of 0.1 °/√h, GYPRO4300 offers a miniature, digital and low-SWaP (Size, Weight and Power) high-performance 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.

Miniature and robust gyro for systems operating under vibration conditions
The closed-loop architecture of Tronics GYPRO4300 offers a strong vibration rejection of 0.5 °/h/g² under harsh conditions. GYPRO4300 gyros are housed in a miniature, hermetic, ceramic J-lead package that ensures long operational and storage life and guarantees high compliance with the stringent thermal cycling requirements of critical applications. They embed fully hard-coded electronics with a 24-bit digital SPI interface for swift integration into INS (Inertial Navigation Systems), IMU (Inertial Measurement Units) as well as AHRS (Attitude and Heading Reference Systems). To minimize mechanical cross-coupling in multi-axis applications, 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) FOG (Fiber Optical Gyroscopes). Due to its solid-state architecture that reduces the number of internal components and system complexity, GYPRO4300 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.

GYPRO4300 gyros are ideally complemented by high-performance Tronics AXO^®300 digital accelerometers that share the same SMD J-lead ceramic package (12 x 12 x 5 mm) and same digital interface to enable low-cost integration, assembly, and reliability on PCB, even in fast-changing temperature conditions.
