Tronics Microsystems - TDK CorporationTronics Microsystems, a subsidiary of TDK Corporation, is a leading manufacturer of high-precision digital accelerometers and MEMS gyros for demanding unmanned systems and autonomous vehicle applications.

We are the market’s only supplier of both high-performance force-rebalance digital SMD accelerometers and gyros, and our MEMS sensors are ideal for incorporation into IMUs and INS for UAVs (unmanned aerial vehicles) and UGVs (unmanned ground vehicles) operating in highly dynamic and challenging environments.

AXO315 MEMS Accelerometer

Digital accelerometer with high bias stability & repeatability for railway, drones, autonomous vehicles and robotics

Precision accelerometers

The AXO315 is a digital high-performance closed-loop MEMS accelerometer designed as a performance-equivalent yet more SWaP (size, weight and power)-efficient alternative to incumbent analogue force-rebalance quartz and mechanical servo-accelerometers. Featuring very low noise and excellent linearity, the AXO315 delivers best-in-class composite bias repeatability and scale factor repeatability under demanding temperature and vibration conditions.

axo high-performance Linear accelerometerEnclosed in a hermetically-sealed SMD (surface mount device) ceramic package, the miniature accelerometer provides a 24-bit SPI interface for easy integration and reduced part counts in PCB designs.

The system is designed with fully hard-coded electronics and no embedded software, and features built-in temperature compensation and self-test.

The digital accelerometer shares the same interface as our GYPRO high performance gyros, making the two MEMS sensors complementary and easy to integrate in IMU and INS. It is also free from dual-use export control.

GYPRO MEMS Gyroscopes

Precision angular rate sensor for railway, drones and autonomous vehicles

GYPRO MEMS Gyros family

The GYPRO family of high-performance digital closed-loop MEMS gyroscopes provides angular rate measurement with ultra-low noise, low latency and high linearity. Designed to provide a digital SMD alternative to expensive and bulky FOG, DTG or quartz gyros, the MEMS sensors offer high bias stability and scale factor repeatability and low angular random walk.

high precision gyroscopesWeighing just 2 grams, the miniature digital gyroscopes are housed in a hermetically-sealed SMT package, and provide a 24-bit SPI interface for easy integration and reduced bills of materials compared to analogue sensors. The design is built around fully hard-coded electronics with no embedded software, and features built-in temperature compensation and self-test.gypro high-performance mems gyroscopes

GYPRO gyros are factory calibrated and temperature-compensated to provide high-accuracy digital output over a broad temperature range. An embedded temperature sensor allows on-chip or external compensation.

The GYPRO family includes four variants:

GYPRO2300 – low noise gyro, standard configuration
GYPRO2300LD – low noise gyro, low delay configuration
GYPRO3300 – low noise gyro, improved vibration tolerance and ultra-low delay configuration
GYPRO4300 – low noise gyro, high bias stability and low ARW – sampling now

GYPRO MEMS gyroscopes are non-classified under dual-use export control.

The versatile sensors are ideal for a wide range of unmanned systems applications, including:

  • GNSS-aided positioning and navigation of trains and land vehicles
  • Antenna and gimbal stabilization and pointing
  • IMU, INS and AHRS (attitude and heading reference systems) for drones and autonomous vehicles
