Tronics Microsystems has developed a new generation of high-performance MEMS inertial sensors designed to meet the demanding requirements of VTOL and aerospace applications, including eVTOL aircraft and UAVs.
While traditional navigation-grade inertial sensors used in commercial aviation have long been bulky and expensive, Tronics’ MEMS-based accelerometers and gyros offer a cost-effective, compact, and energy-efficient alternative without compromising on performance.
Engineered for environments that involve rapid temperature fluctuations and high vibration levels, Tronics sensors deliver exceptional stability, repeatability, and reliability. These digital MEMS accelerometers and gyros feature excellent bias stability and shock rejection, making them ideal for GNSS-assisted navigation systems and Attitude and Heading Reference Systems (AHRS). Their low-SWaP (size, weight, and power) design ensures compatibility with the payload and power constraints of modern VTOL aircraft and UAVs.
Key applications include flight control systems, GNSS-assisted positioning and navigation, aerial surveying and mapping, standby flight instruments, and gimbal or optical sensor stabilization.
Tronics’ AXO®300 accelerometers provide a low bias residual error of just 0.5 mg and 1 mg composite bias repeatability over a wide temperature range. Complementing them, the GYPRO®4000 gyros offer low Angular Random Walk (ARW) and bias instability for precise navigation and attitude control. Housed in lightweight ceramic SMD packages with digital SPI outputs, these sensors streamline integration and minimize system complexity, empowering the next generation of high-performance, lightweight aerospace platforms.
