F80 type Medium and high precision fiber optic gyroscope
Stability time s1 Introduction
fiber optic gyroscope as a new type of all-solid-state optical gyroscope, using 1310 or 1550 scheme, has the advantages of fast start-up, wide measurement range and high reliability. F80 type single-axis medium-high precision fiber optic gyroscope instrument can be applied to the application requirements of medium-high precision inertial guidance system such as land positioning orientation, vehicle-mounted north finder, airborne heading, marine gyroscope compass, etc.
