Safran STIM300 Tactical-Grade High-Performance MEMS IMU
Vendor: Safran Navigation & Timing (法国, 原 Sensonor)
Product: STIM300 战术级高精度 IMU
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.
