The HTG series three-axis integrated high-precision fiber optic gyro is based on single axis fiber optic gyroscope technology, adopting a design where the sensor head, light source, and circuit are separated. The three-axis gyroscope shares an erbium-doped fiber light source and a signal processing circuit, achieving the design goal of three-axis integration. This series of fiber optic gyro has the advantages of no preheating, low power consumption, good synchronization, and strong overload resistance. At the same time, the design is relatively flexible, making it easier to achieve the “three in one” design requirements of generalization, serialization, and combination. The IMU (Inertial Measurement Unit) based on this type of fiber optic gyroscope is one of the main development directions of the company.
