High stability and repeatability for navigation
AXO®305 is a high performance, single axis closed-loop digital MEMS accelerometer with ±5 g input range that offers a performance equivalent and low-SWaP alternative to precision quartz accelerometers at a fraction of their size, weight and power.
Its superior 1-year composite bias repeatability of 1 mg makes AXO®305 a perfect candidate for integration into high performance Inertial Measurement Units (IMU), Inertial Navigation Systems (INS) with GNSS data fusion and Motion Reference Units (MRU) for land, railway, marine and subsea applications.
The hermetic ceramic SMD package combined with a 24 bits SPI interface eases the integration of AXO®305 and reduces the BOM. The built-in self-test ensures initial verification of the sensor’s integrity and continuous in-operation functionality test.
MEMS accelerometer for land and marine navigation
With a bias instability of 3 µg, AXO®305 is a high performance MEMS accelerometer for positioning and navigation of manned and unmanned ground vehicles, underwater robots and drones, and boats.
In addition, it is a perfect candidate for integration into Motion Reference Units (MRU) used for ship motion control and dynamic positioning, platform stabilization and precision robotics.
