TDK has introduced the GYPRO 4300 digital MEMS gyroscope with high stability for dynamic applications

TDK has introduced Tronics GYPRO 4300, a digital MEMS gyroscope with high stability and excellent vibration resistance. The element is ideal for dynamic applications with an input range of ±300°/s, a support bandwidth of 200 Hz, a delay of 1 ms, and a closed-loop structure that ensures high linear accuracy and stability even in dynamic environments.

The GYPRO4300 is the first product prototype of Tronics' GYPRO4000 new high-performance digital MEMS gyroscope platform, which complements the recently announced AXO300 closed-loop digital accelerometer platform.

Accurate navigation and positioning in dynamic applications

A miniature, digital, and low-swap (size, weight, and power) high-performance MEMS gyroscope, the GYPRO4300 features a typical zero-bias stability of 0.5°/h (up to 2°/h) and an ARW of 0.1°/√h (gyro Angle random Walk). It lays the foundation for a new generation of precision positioning, navigation and stabilization capabilities in a variety of dynamic applications, such as railways, land vehicles, VTOL (vertical takeoff and landing) aircraft and UAVs (unmanned aerial vehicles), Marine and subsea systems, as well as drilling and measuring instruments.

Small and robust gyroscope for systems under strong vibration conditions

Tronics GYPRO4300 gyroscope adopts closed-loop structure design, with excellent vibration resistance up to 0.5°/h/g², suitable for harsh working conditions. The gyroscope's micro-sealed J-lead ceramic package ensures a long operating and storage life, meeting the stringent thermal cycle requirements of critical applications. In addition, the gyroscope is embedded with a fully hard-coded electronics with a 24-bit digital SPI interface for rapid integration into INS (Inertial Navigation System), IMUs (Inertial Measurement Unit), and AHRS (Attitude and Heading reference System). To minimize mechanical cross-coupling in multi-axis applications, the GYPRO4300 is also available in 3 frequency ranges.

Low SWaP gyroscope with high cost performance and high reliability

Featuring a miniature package and low power consumption, the Tronics GYPRO4300 gyroscope provides a digital, low-cost, and low-swap alternative that is well suited to replace other bulky, expensive, and power-hungry solutions such as DTG (power-tuned gyroscope) and FOG (fiber optic gyroscope). The solid state structure of the GYPRO4300 also reduces the number of internal components and system complexity, and the MTBF (mean time between failures) exceeds 1,000,000 hours, more than 10 times the current equivalent performance of DTG and FOG. In addition, the built-in self-test function not only initially verifies the integrity of the sensor, but also enables continuous operational functional testing.

The GYPRO4300 gyroscope is a useful complement to the high-performance Tronics AXO®300 digital accelerometer. Both Gypro4300 Gypro4300 Gypro4300 Gypro4300 Gypro4300 Gypro4300 Gypro4300 Gypro4300 Gypro4300 Gypro4300 Gypro4300 Gypro4300 Gypro4300 is a useful complement to the high-performance Tronics AXo ®300 digital accelerometer. Both Gypro4300 Gypro4300 gyroscopes share SMD J lead ceramic package (12 x 12 x 5 mm) and are equipped with the same digital interface. Even in severe conditions of sudden temperature change is no exception.
