Tronics Microsystems specializes in MEMS inertial sensors tailored for attitude and heading reference systems (AHRS) and flight control applications.
This innovative series of digital MEMS inertial sensors facilitates accurate navigation and positioning in advanced air mobility systems, including Vertical Take-Off and Landing (VTOL) aircraft and Unmanned Aerial Vehicles (UAVs). Their versatility extends to GNSS-assisted navigation, Inertial Navigation Systems (INS), and Inertial Measurement Units (IMU).
Tronics’ tactical-grade MEMS inertial sensors present a compact, low-SWaP (size, Weight, and Power) option to conventional quartz accelerometers and Fiber Optic Gyroscopes (FOG). They are engineered to perform exceptionally well in high-vibration environments while minimizing power consumption,thereby enhancing the operational endurance of aircraft.
The MEMS accelerometers and gyroscopes from Tronics are encased in a lightweight, compact ceramic SMD package, optimizing UAV payload capacity. Unlike analog sensors, these devices feature a digital SPI output, which not only reduces material costs but also simplifies system integration.
