This is the constant of proportionality between the actual gyro rotation about its sensitive axis and the gyro indicated output. In our gyro the output is either in volts/degree/sec (analog) or degrees/bit (digital). The digital gyro output can also be interpreted as the average rotation rate in degrees/sec/bit by multiplying the value by a factor of 10.
The DSP-3000 family is a commercial-grade gyro.  It was not designed specifically or adapted to military use. Further, no government funds were used in its development. Many of our designs are made robust with MIL STD specifications in mind but the DSP-3000 has not been tested or qualified to meet military standards.

The DSP-4000 is an example of a gyro with the same performance characteristics as the DSP-3000. In this case the gyro has been repackaged specifically for military end use and as such falls under Category XII (e) State Department Classification. It also has undergone military qualification testing.

Also called the sensitive axis, the input axis is a line perpendicular the plane of the fiber coil and the mounting plate of the gyro. A fiber optic gyro is a true single-axis rate sensor and does not respond to rotations in other axial directions; it is thus said to be insensitive to "g" forces. An arrow on the side of the gyro indicates the sense of rotation that yields a positive rate. Inverting the gyro would change the sign of the rate, but note that the arrow still points in the direction of the positive rate.

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).

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.
