High stability and repeatability for precision navigation in severe vibrations conditions
AXO314 is a cost-effective high precision digital MEMS accelerometer with ±14 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 combined with a Vibration Rectification Error (VRE) of 20 µg/g² make AXO314 a perfect candidate for integration into high performance Inertial Measurement Units (IMU) and Inertial Navigation Systems (INS) used in UAV, ships, aerial survey and mapping, and drilling guidance in mining applications.
The hermetic ceramic SMD package combined with a 24 bits SPI interface eases the integration of AXO314 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 navigation of dynamic applications
With a bias instability of 4 µg and an operating temperature from -40°C to +85°C, AXO314 is a high precision MEMS accelerometer tailored to GNSS-assisted inertial navigation and positioning of UAV, land and marine transportation systems.
In addition, it is a perfect candidate for integration into Inertial Measurement Units (IMU) used for guidance and orientation of drilling and survey instruments used in mining industry. Its miniature package allows to build high precision inertial systems exhibiting a compact form-factor that fits into a low diameter tube.
