A:

Strong magnetic fields have the ability to cause apparent drift in the gyro bias. This is due to the Faraday effect on the laser light in the sensing coil resulting in non-reciprocal light paths. While this effect can be observed in gyros designed for precision inertial navigation systems (drift rates of less than 1 degree per hour), and can be mitigated by the use of mu-metal shielding, there have been no reported problems with KVH FOGs. If your application results in mounting a FOG near a very strong magnetic field (>50 gauss), a practical test to determine sensitivity is suggested.

A:
Yes, all of KVH's FOGs have the capability of being combined with GPS, making integrated GPS/INS, AHRS, and inertial measurement units a reality.
A:
Designed and tested to rigorous military standards, the rugged DSP-4000 series meets or exceeds required military specifications and offers the military the next generation of gun and turret stabilization as well as dynamic pointing capabilities. The DSP-4000 is ideal for demanding applications, including platform positioning and stabilized pointing, gun and turret stabilization, and antennas/optical/camera stabilization.
A:

Technical specifications and complete details are available on the DSP-4000 Product Page .

A:

The DSP-4000 fiber optic gyro (FOG) is a low-cost, high-performance alternative to mechanical gyros. It offers superior stabilization of both single- and dual-axis configurations specifically designed to provide the military with a successor to troublesome mechanical gyros. For complete product details, please visit the DSP-4000 Product Page.

A:
The DSP-4000 uses an all-fiber design with no moving parts to wear out or fail, ensuring high reliability, superior performance, and exceptional vibration, shock, and acceleration survivability. The DSP-4000 series also features low noise, high bandwidth, improved bias stability, and excellent resolution.

Unlike mechanical gyros, the DSP-4000 series is insensitive to cross-axis motion and inertia and its high bandwidth makes it particularly suitable for armored vehicle gun stabilization.
