The cased 3-Space™ USBC-H-C provides 10-DOF sensing and onboard orientation processing in a compact package with screwdown or strapdown mounting. The AHRS/VRU/IMU incorporates a triaxial gyroscope, dual auto-selecting accelerometers, magnetometer, and barometric pressure sensor for robotics and unmanned vehicle integration.
Low-range acceleration sensing ranges from ±2g to ±16g, with high-range measurements up to ±320g. QGRAD3 or Extended Kalman filtering provides update rates up to 2,000 Hz, with an integrated World Magnetic Model for true, magnetic, or grid north heading. USB-C, UART, and RS232 interfaces provide host connectivity.
A board-level variant, the USBC-H-B, is also available.
