Fibre Optic Gyroscopes (FOG) Spare Parts Suppliers
A fibre optic gyroscope, or FOG, measures rotation with no moving parts: it sends light both ways around a coil of fibre and reads the tiny shift that rotation creates. That solid-state design is why it has replaced spinning-mass gyros in marine gyrocompasses, inertial navigation systems, and motion reference units, and why it fails so rarely. When one does fail, it is precision optics and electronics, and the fix is a part matched to the exact unit. Fibre optic gyroscope spare parts suppliers carry those parts, for makers such as iXblue, KVH, EMCORE, and Advanced Navigation.
What Gets Ordered
Because a FOG has no bearings to wear, the parts that fail are the electronics rather than anything mechanical. The order is usually the sensor module itself, the detector and processing boards, the power supply, or the interface that ties the gyro into its gyrocompass or INS. The fibre coil at the heart is rarely serviced on its own; a failed sensor is replaced as a unit. Because the gyro is a sensor inside a larger system, it often reaches the ship as part of an inertial navigation system spares package rather than on its own.
Match and Export Control
A fibre optic gyroscope is a closed, calibrated device, so a spare is specified against the exact model and usually supplied through the OEM or an authorised channel. Many fiber optic gyroscopes are also dual-use and export-controlled, which brings end-use documentation into the order alongside the part number. These are high-value items, often supplied as exchange or reconditioned units against a core, and fitting a replacement means recalibration, handled through fibre optic gyroscope services rather than a straight swap.
Give the gyroscope maker, the model, and whether the fault sits in the sensor or its electronics, and the fibre optic gyroscope spare parts suppliers listed here can identify the module or board that fits. Nothing in this category is generic, and the calibration that follows is as much part of the job as the part itself.
