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 recalibrating and is totally maintenance free. They have very high reliability (MTBF) and no maintenance requirements during its service life.

Designed for autonomous navigation and guidance of aviation, land, marine and subsea vehicles, Fiber Optical Solution’s strapdown inertial navigation systems are compact, robust and maintenance-free, low-consumption units.
