Safran Navigation & Timing (formerly Sensonor, Norway) STIM300 is a small, lightweight, high-performance non-GPS-aided tactical-grade MEMS IMU containing 3 highly accurate MEMS gyros, 3 high-stability accelerometers and 3 inclinometers, factory calibrated and temperature compensated. Gyro full scale ±400 °/s (output capped at ±480 °/s) with 262 Hz bandwidth and up to 2000 samples/s; 0.3 °/h bias instability and 0.15 °/√h angular random walk (Allan variance, 25 °C), 3 °/h drift-rate stability over temperature; the ±10 g accelerometer shows 0.04 mg bias instability and 0.07 m/s/√h velocity random walk; axis misalignment is just 1 mrad. Single +5 V supply at 1.5~2 W, RS422 interface, 55 g mass, ITAR-free — a cost-effective FOG-class alternative for precision navigation on humanoid robots, robot dogs, unmanned systems and stabilization platforms.
Analog Devices (USA) ADIS16470 is the iSensor wide-dynamic-range miniature MEMS IMU, integrating triaxial digital gyroscope and accelerometer with signal conditioning in an ~11 × 15 × 11 mm 44-ball BGA module. Gyro full range ±2000 °/s with 8 °/h in-run bias stability and 0.008 °/s/√Hz rate noise density; accelerometer ±40 g range. Every axis is factory calibrated for sensitivity, bias and alignment (calibration range −10 to +75 °C); SPI interface with automatic/manual bias correction, −25 to +85 °C operation. With its high dynamics and low drift, the ADIS16470 is widely used for SLAM, attitude estimation and stabilization on humanoid robots, robot dogs, drones and mobile platforms.
