Tronics Microsystems, a leading developer of high-precision digital MEMS accelerometers and gyros for demanding unmanned systems and autonomous vehicle applications, has partnered with Unmanned Systems Technology (“UST”) to demonstrate their expertise in this field. The ‘Silver’ profile highlights how their 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.

MEMS accelerometersThe 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.

Enclosed in a hermetically-sealed SMD 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 sensors complementary and easy to integrate in IMU and INS. It is also free from dual-use export control.

high precision gyroscopesThe 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 sensors offer high bias stability and scale factor repeatability and low angular random walk.

Weighing just 2 grams, the miniature gyros 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 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.
