AXO305 is a high‑performance digital MEMS accelerometer (inertial sensor) launched by Tronics, a subsidiary of TDK.

Accelerometer sensors can calculate the tilt of a device using gravity to detect device orientation.They are used to sense screen orientation switching or hand gestures for smartphones and game consoles. On drones, they work in conjunction with gyroscope sensors for attitude and heading control.

The AXO305 is a high‑performance digital MEMS accelerometer (inertial sensor) from Tronics, a subsidiary of TDK. Part of the AXO®300 series, it is designed for precision motion control and navigation in land, marine and robotic applications.

AXO305 Accelerometer

Core Functions

Measures linear acceleration within the ±5g range and outputs digital signals via the SPI interface.Adopts a closed‑loop architecture to maintain high linearity and stability even under heavy vibration, with a vibration‑rejection performance of 20 μg/g².Delivers 4 μg bias stability and ±0.5 mg full‑temperature‑range bias error to support high‑precision inertial navigation.

Core Value

Serves as the core sensing unit for IMU/INS to enable continuous navigation in GNSS‑denied environments.Applied in Motion Reference Units (MRU) to support vessel dynamic positioning and attitude stabilization.Provides high‑precision tilt and vibration feedback for platforms, antennas and cranes to ensure stable control.Enables motion control for AUV/ROV underwater navigation and precision robots.

Application Scope

Land Systems: GNSS‑aided navigation and motion control for manned/unmanned vehicles and railway locomotives.Marine Engineering: Vessel dynamic positioning, offshore platform attitude monitoring, and AUV/ROV underwater navigation.Industrial Automation: Precision robots, crane stabilization systems, and anti‑shake control for antennas and platforms.
