Compact, Robust, Single or Multi-Axis Gyros

Nine different configurations make the DSP-1760 Fiber Optic Gyro (FOG) a highly adaptable, easy-to-integrate solution for meeting a wide range of stabilization and navigation applications. The DSP-1760 allows the end user to select 1-, 2-, or 3-axes of the world’s smallest high-performance FOGs in an unhoused OEM configuration or housed in an environmentally-sealed, compact housing. The three unhoused variants are available with a Micro-D connector, while the housed variants are available with either a Micro-D or circular connector.

Superior Reliability and Accuracy

The DSP-1760 features a solid state design with exceptional bias stability, scale factor and Angle Random Walk (ARW). This high bandwidth/low-noise angular rate sensor is a navigation-grade gyro particularly well-suited for providing extremely accurate data for a variety of demanding military applications. It is an optimal stabilization and pointing solution for military vehicles, vessels, and aircraft with traditional weapons and turrets, as well as Remote Weapons Stations that must be stabilized for reliable on-the-move operation.

Unsurpassed Fiber Technology for Diverse Applications
The DSP-1760 relies on KVH’s exclusive E•Core ThinFiber, the world’s smallest D-shaped optical fiber. By reducing the overall diameter of the fiber, the resulting E•Core ThinFiber enables a greater length of fiber in the DSP-1760’s optical circuit, thereby dramatically increasing the accuracy of the gyros. The DSP-1760 is ideal for platform stabilization for land, sea, and aerial systems; navigation, guidance and control systems; and stabilization and navigation of unmanned and manned systems as well as stabilization of their payloads.

A rate gyro does not output accumulated angle. Instead, it outputs rate of change of angle. In most KVH FOGs, the users can change the output format as desired; rate integrated angle, or incremental angle.


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.

Exclusive Technology

E•Core ThinFiber

KVH’s proprietary polarization maintaining E•Core ThinFiber delivers outstanding performance in much smaller sized gyros, such as the DSP-1760. By reducing the overall diameter of KVH’s standard E•Core fiber, the resulting E•Core ThinFiber dramatically increases the accuracy of our standard size gyros, and results in small FOGs that deliver extremely high bandwidth and low noise.

DSP Technology

KVH’s Digital Signal Processing (DSP) electronics improve fiber optic gyro performance in such critical areas as scale factor and bias versus temperature, scale factor linearity, turn-on to turn-on repeatability, and bias stability. The innovative DSP design is covered by multiple patents and overcomes the limitations of analog signal processing, virtually eliminating temperature-sensitive drift and rotation errors.
