KVH is pleased to offer world-class support and warranty coverage for all of its products. Complete details regarding all KVH product warranties are available on global support pages.

A:
The DSP-3000 Fiber Optic Gyro (FOG) is based on the Sagnac principle. With no moving parts to wear out, this design has a MBTF of >55,000 hours. The optical circuit design combines KVH's proprietary elliptical core polarization-maintaining optical fiber and fiber components with the companyís patented digital signal processing producing our highest performing fiber optic gyro to date.
A:

The temperature specification presumes that the gyro is mounted to a metallic surface that is at no higher temperature than the ambient air. Although a bare metal surfaces is best, a painted surface is acceptable. Surfaces with poor conduction will reduce the upper temperature limit of performance. The indicated reading of the internal temperature sensor should not, under any circumstances, be permitted to exceed 85°C (185°F).

A:
KVH's digital signal processing (DSP) technology represents a breakthrough in open-loop fiber optic gyro design that enables KVH Industries to support a wide range of applications ranging from stabilized weapons to torpedo guidance, drone and unmanned aerial vehicle navigation, land vehicle navigation, and smart munitions guidance. The DSP class of gyros is not only suitable for use in these and a variety of commercial applications but they are also offer significant cost advantages over competing ring laser and closed-loop fiber optic gyros.

The combination of accuracy, versatility, and value make these systems extremely attractive and reliable solutions for the most demanding applications.
A:
The FOG is an analog sensor and, as such, it has an output offset. This means that the output voltage at zero rotational rate is not necessarily zero. To obtain zero output at zero rotational rate, measure the output voltage at the beginning after turn-on when you know the gyro is not rotating and subtract it from further measurements.
