TDK Corporation has unveiled the Tronics GYPRO4300, a digital MEMS gyroscope designed for high stability and resistance to vibrations, making it ideal for dynamic applications.
This innovative gyroscope boasts an input measurement range of ±300 °/s,a bandwidth of 200 Hz,and a latency of just 1 ms. It’s closed-loop design guarantees remarkable linearity and stability, even in challenging environments. The GYPRO4300 marks the inaugural product in the new high-performance digital MEMS gyro platform, GYPRO4000.
Accurate Navigation and Positioning for Dynamic environments
With a typical bias instability of 0.5 °/h (maximum of 2 °/h) and an Angular Random Walk (ARW) of 0.1 °/√h, the GYPRO4300 is a compact, digital, and low-SWaP MEMS gyroscope. TDK envisions this technology as a catalyst for a new era of precise navigation, positioning, and stabilization in various dynamic applications, including vertical takeoff and landing (VTOL) aircraft, unmanned aerial vehicles (UAVs), marine systems, railway transport, land vehicles, borehole drilling, and surveying tools.
Compact and Resilient Gyroscope for vibration-Prone Systems
The closed-loop design of the Tronics GYPRO4300 provides robust vibration rejection, rated at 0.5 °/h/g², even under severe conditions. Encased in a miniature, hermetically sealed ceramic J-lead package, the GYPRO4300 ensures longevity and meets stringent thermal cycling standards essential for critical applications. It features fully hard-coded electronics with a 24-bit digital SPI interface, facilitating seamless integration into Inertial Navigation Systems (INS), Inertial Measurement Units (IMU), and Attitude and Heading Reference Systems (AHRS). To reduce mechanical cross-coupling in multi-axis setups, the GYPRO4300 is available in three distinct frequency ranges.
Cost-Effective,Low-SWaP,and Highly Reliable Gyroscope
Thanks to its compact design and low power requirements,TDK positions the Tronics GYPRO4300 as a digital,cost-effective,and low-SWaP option to larger,more expensive,and power-hungry solutions like Dynamically Tuned Gyros (DTG) and Fiber Optical Gyroscopes (FOG). its solid-state architecture minimizes internal components and system complexity, resulting in a Mean Time Between Failure (MTBF) exceeding 1,000,000 hours—over ten times better than traditional DTG and FOG with comparable performance.Additionally, the built-in self-test feature provides initial verification of the sensor’s integrity and ongoing functionality checks during operation.
The GYPRO4300 is ideally paired with the high-performance Tronics AXO300 digital accelerometers, which share the same SMD J-lead ceramic package (12 x 12 x 5 mm) and digital interface, allowing for cost-effective integration and reliability on PCBs, even in rapidly changing temperature environments.
Future expansions of the GYPRO4000 gyros platform will introduce new product references tailored to specific application needs, such as enhanced bias stability, reduced ARW, and lower in-band noise for accurate attitude determination.
