Abstract

Compared with laser gyroscope, it is still difficult for the scale factor stability of high-precision fiber optic gyroscope (FOG) to achieve better than 1ppm under variable temperature conditions due to the influences of the fiber coil and the light source. We proposed to add multiple precision temperature measuring devices to the fiber coil, and established a multi-modulus temperature compensation model by measuring the temperature at multiple locations of the fiber coil. The stability of the FOG scale factor is greatly improved.
