Fiber Optical Solution’s fiber-optic strapdown inertial navigation systems (SINS) have complete solid-state design with no rotating or other moving parts. Because it has no moving parts, there is nothing to go out of alignment and therefore it never requires re-calibrating and is totally maintenance free. They have very high reliability (MTBF) and no maintenance requirements during its service life.
