A Study on the Fabrication of a Fiber Optic Gyrocompass for Ships

A fiber optic gyrocompass for ships was made in consideration of cost, reliability and convenience. In order to reduce the cost a cheaper fiber sensor was used in this system. The accuracy was increased by replacing a 180ppr-slit disk with a 1000ppr-encoder. The reliability was also increased by improving the signal processing electronics. This system was made as a heading display type for convenience. Although more inexpensive FOG than that of the previous system was used, the accuracy of this compass was increased about 0.5˚. Moreover, it has a very fast warm-up time of about 5 minutes. Therefore, this compass can show the prospect of practical use on ships if it is installed on a stabilizer against the dynamic motion such as rolling and pitching.
