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

The GYPRO4300 is suitable for applications such as railway, land vehicles, VTOL aircraft and UAV, marine and subsea systems, borehole drilling and surveying instruments.

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.
