SD232 Optical Fiber Inertial Navigation System

The product has self-calibration, self-alignment and self-detection functions, and can realize independent maintenance and protection at the base level. It is a typical intelligent single machine; it has a built-in dual-axis index locking mechanism and has multiple positions under the three-self function. The dual working attributes of “flip” and “reliable locking during flight”; The product is a Strapdown Inertial Navigation System consisting of high-precision fiber optic gyroscope and quartz accelerometer. The main features of the product are as follows:
