Fiber Optic Gyro (FOG) - Stability under pressure

Saab’s Fiber Optic Gyros (FOG) are a vital component in many different platforms, including radar, gun, camera and antenna applications. We design gyro solutions by adapting sensors and modular electronics to suit each individual requirement.

Saab’s Fiber Optic Gyros

Our Fiber Optic Gyros (FOG) are a vital component in many different platforms, including radar, gun, camera and antenna applications. We design gyro solutions by adapting sensors and modular electronics to suit each individual requirement.

The Saab FOG sensor is a fiber optic ring interferometer comprising fiber coil, phase modulator, two fused fiber optic couplers, fiber optic polarizer, super-luminescent light module and photo receiving module with pre-amplifier. The electronic part is a processing PCB that converts the optical module output into rate proportional voltages.

In addition to offering and selling standard configurations a typical procedure for us is to design complete rate gyro solutions by adapting our sensors and our modular electronics to customer requirements. The basic configuration data-sheets available as downloads are examples of standard configurations which could be modified to different customer requirements.

Strenghts

  • Solid state
  • Short start up time
  • High sensitivity
  • Low drift
  • Low noise
  • High bandwidth
  • High shock usability
  • Small size
  • No ITAR restrictions

Applications:

  • Gun stabilisation
  • Remote Weapon Station stabilisation
  • Sight stabilisation
  • Antenna stabilization

The most important part of the Saab offering is to adapt our basic FOG components to the customer’s specific need. Saab can also provide customised packages according to the actual mechanical outlines, to provide a form, fit and function replacement for older designs based on mechanical gyros.
