Detection range ±400°/s, bias stability ≤0.03°/h, accelerometer, magnetic sensor, barometer, GNSS, capable of continuous operation for over 10,000 hours.
The INS912 series uses fiber optics in its gyroscope. Detection range ±400°/s Bias stability <0.03°/h (INS912-2A) <0.07°/h (INS912-3A) <0.3°/h (INS912-3B) Additionally, it consists of accelerometers using quartz, a 3-axis magnetic sensor, a barometer, and a multi-mode GNSS module, which optimally fuses information from inertial navigation, GNSS, and speedometer using navigation algorithms. Even in conditions where GNSS cannot be relied upon, it provides highly accurate information on attitude, heading, position, and speed. It can also connect with various external sensors, enabling continuous operation for over 10,000 hours.
