AXO315 MEMS Accelerometer
Digital accelerometer with high bias stability & repeatability for railway, drones, autonomous vehicles and robotics
The AXO315 is a digital high-performance closed-loop MEMS accelerometer designed as a performance-equivalent yet more SWaP (size, weight and power)-efficient alternative to incumbent analogue force-rebalance quartz and mechanical servo-accelerometers. Featuring very low noise and excellent linearity, the AXO315 delivers best-in-class composite bias repeatability and scale factor repeatability under demanding temperature and vibration conditions.
Enclosed in a hermetically-sealed SMD (surface mount device) ceramic package, the miniature accelerometer provides a 24-bit SPI interface for easy integration and reduced part counts in PCB designs.
The system is designed with fully hard-coded electronics and no embedded software, and features built-in temperature compensation and self-test.
The digital accelerometer shares the same interface as our GYPRO high performance gyros, making the two MEMS sensors complementary and easy to integrate in IMU and INS. It is also free from dual-use export control.
The versatile MEMS sensor is ideal for a wide range of unmanned systems applications, including:
GNSS-aided positioning and navigation of trains and land vehicles
Incorporation into IMUs (inertial measurement units) for ROVs (remotely operated vehicles), railway, drones and autonomous vehicles
Integration into INS (inertial navigation systems) for UGVs (unmanned ground vehicles) and land-based robotics
Digital closed-loop accelerometer with high resolution and stability for high-vibration environments
The AXO®301 is a high-accuracy single axis closed-loop MEMS accelerometer designed to provide acceleration and deceleration measurements for high-vibration applications such as UGVs (unmanned ground vehicles), land robotics and automated train control.
Providing a performance-equivalent and cost-effective alternative to quartz and servo-accelerometers, the miniature accelerometer is enclosed in a hermetic SMD package, making it ideal for even the most SWaP (size, weight and power)-limited applications.
Featuring a 24-bit digital SPI interface, the AXO®301 can be easily integrated into high-performance IMU and INS designs. The system’s built-in self-test capability ensures initial verification of the sensor’s integrity and continuous in-operation functionality.
Digital closed-loop accelerometer for unmanned vehicle IMU & INS
The AXO®305 is a high-performance single-axis closed-loop digital MEMS accelerometer with a ± 5g input range. Featuring an excellent 1-year composite bias repeatability of 1mg, it is ideal for integration into IMUs, INS and MRUs for high-precision navigation and positioning of drones and robotics.
The low-SWaP accelerometer is highly suited as a replacement for bulkier and costlier quartz accelerometers, featuring a 24-bit digital SPI interface for ease of integration and reduction in BOM components.
The hermetically sealed unit also includes a built-in self-test capability that provides initial verification of the sensor’s integrity and continuous in-operation functionality.
Precision angular rate sensor for railway, drones and autonomous vehicles
The GYPRO high-performance digital closed-loop MEMS gyroscopes provide angular rate measurement with ultra-low noise, low latency and high linearity. Designed to provide a digital SMD alternative to expensive and bulky FOG, DTG or quartz gyros, the MEMS sensors offer high bias stability and scale factor repeatability and low angular random walk.
Weighing just 2 grams, the miniature digital gyroscopes are housed in a hermetically-sealed SMT package, and provide a 24-bit SPI interface for easy integration and reduced bills of materials compared to analogue sensors.
The design is built around fully hard-coded electronics with no embedded software, and features built-in temperature compensation and self-test.
GYPRO gyros are factory calibrated and temperature-compensated to provide high-accuracy digital output over a broad temperature range. An embedded temperature sensor allows on-chip or external compensation.
