Rugged High Performance Surface Gyrocompass 1 Axis Fibre Optic Gyroscope for Vessels FOG600


Product Description

FOG600 Single Axis Fiber Optic Gyroscope uses a single axis fibre optic gyro sensor, mounted inside an extruded aluminum housing and can typically reduce heading drift errors more effectively than most magnetically referenced aircraft gyros.

An on-board processor manages the gyro sensor interface, mode selection, power supplies and water ingress sensing.

FOG600 provides internal compensation for pitch and roll angles and adopts proprietary slaving algorithms, it then provides an output of stabilized heading with low drift rate optimized for pitch and roll angles.

SkyMEMS’s FOGs are setting the new benchmark for tactical and navigational grade gyros for a wide variety of guidance, navigation and aeronautics applications. FOG600 is the Right choice when selecting a precision solid-state gyroscope component for tactical grade applications.

FAQ

What is the Operation of fiber optic gyroscope?

Two beams from a laser are injected into the same fiber but in opposite directions. Due to the Sagnac effect, the beam travelling against the rotation experiences a slightly shorter path delay than the other beam. The resulting differential phase shift is measured through interferometry, thus translating one component of the angular velocity into a shift of the interference pattern which is measured photometrically.

Beam splitting optics launches light from a laser diode into two waves propagating in the clockwise and anticlockwise directions through a coil consisting of many turns of optical fibre. The strength of the Sagnac effect is dependent on the effective area of the closed optical path: this is not simply the geometric area of the loop but is enhanced by the number of turns in the coil. The FOG was first proposed by Vali and Shorthill in 1976. Development of both the passive interferometer type of FOG, or IFOG, and a newer concept, the passive ring resonator FOG, or RFOG, is proceeding in many companies and establishments worldwide.
