Strapdown inertial navigation systems based on fiber-optic gyroscopes

Strapdown inertial navigation systems (SINS) are basic parts of modern integrated navigation systems in various vehicles. Currently, fiber-optic gyroscopes (FOGs) with closed-loop feedback are finding increasing use for inertial navigation systems. The paper presents SINS-500K, SINS-500M and SINS-501 developed and produced by the Russian Research & Production Company Optolink with Optolink FOGs. The test results are discussed. Optolink FOGs and SINS’s are compared with similar devices of world leading manufacturers.
