Inertial navigation with high performance MEMS inertial sensors
Digital MEMS accelerometers and gyros with high bias stability and repeatability
Precision acceleration and angular rate measurement for inertial navigation
Discover AXO®315
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).
Discover GYPRO®4300
The GYPRO®4300 is a high performance, closed-loop digital MEMS gyroscope with ± 300 °/s input range that offers a lower cost alternative to entry-level Fiber-Optic Gyroscopes (FOG) at a fraction of their size, weight and power consumption. It features a hermetic SMD ceramic package and a 24 bits SPI interface that ease its integration and reduce the BOM.
Its superior bias stability and repeatability of 10°/h make GYPRO® 4300 an industry-leading MEMS sensor to build high performance IMU (Inertial Measurement Units) for attitude and motion control systems, as well as INS (Inertial Navigation Systems) for GNSS-aided positioning and navigation in dynamic applications
