Technology Details

Exclusive Technology

E•Core ThinFiber Technology

KVH’s proprietary polarization maintaining E•Core ThinFiber delivers outstanding precision performance in much smaller gyros and inertial systems. By minimizing the diameter of KVH’s standard E•Core fiber, the resulting ThinFiber boosts the accuracy of all KVH gyros, and allows the production of very small FOGs with very high bandwidth and very low noise.

DSP Technology

KVH’s DSP electronics improve FOG performance in critical areas such as scale factor and bias vs. temperature, scale factor linearity, and maximum input rate. KVH’s exclusive DSP design is covered by multiple patents* and overcomes the limitations of analog signal processing, eliminating temperature-sensitive drift and rotation errors.

* This product is covered by one or more patents, including U.S. Patent #6,429,939, "DSP Signal Processing for Open Loop Fiber Optic Sensors."
