Add to Cart
16488HA is a high-performance MEMS inertial measurement unit combining a three-axis gyroscope and a three-axis accelerometer to provide accurate angular rate and acceleration data. Measuring up to ±450°/s and ±20 g, with 0.3°/h gyro zero-bias instability and 0.25 mg accelerometer bias, it ensures high-precision inertial navigation. Onboard compensation corrects temperature variations (-45~85 °C), installation misalignment, and nonlinear effects. Its SPI communication at 8–15 MHz, compact design, 1.5 W power consumption, 250 Hz bandwidth, and 0.1 % cross-axis coupling make it ideal for UAVs, industrial automation, autonomous vehicles, robotics, and mobile mapping systems.
