Precision acceleration and velocity measurement for GNSS-assisted navigation
AXO®315 is a high performance, closed-loop, single-axis in-plane digital MEMS accelerometer which offers a lower cost alternative to quartz accelerometers at a fraction of their size, weight and power consumption. Its hermetic SMD package combined with its 24 bits SPI interface eases its integration and reduces the BOM.
With a 1 year composite bias repeatability of 1 mg under demanding temperature and vibrations conditions, the AXO®315 overpasses all commercially available MEMS accelerometers and is a perfect candidate for integration into high performance Inertial Measurement Units (IMU) and Inertial Navigation Systems (INS).
