Extremely High Bandwidth and Very Low Noise
KVH’s DSP-1750 FOG is the smallest high performance fiber optic gyro in the world. Designed for ease of integration, the DSP-1750 has a two-piece design allowing the optical sensors to be installed directly on the sensitive axis, with the gyroscope’s control circuit cards integrated elsewhere in the system. The DSP-1750 FOG uses KVH’s unique 170-micron E•Core ThinFiber, the smallest D-shaped optical fiber which is capable of delivering extremely low noise with very high bandwidth.

Designed for Ease of Integration
The DSP-1750 offers numerous configurations to meet the needs of a wide range of stabilization, guidance, precision pointing and navigation applications. The 1750 FOG is available in dual and single axis configurations with digital or analog outputs. The flexible, adaptable design of the DSP-1750 gyro is ideal for defense and commercial applications in which low payload weight, compact size and high performance are critical to success. This gyro provides cost effective solutions for a vast number of precision pointing, stabilization and navigation applications including stabilization of weapon and equipment platforms, navigation and stabilization for autonomous vehicles for land, sea and air, stabilization of longer-range optical and sensor systems, high-speed gimbals, tactical missiles and more.

At this time, the DSP-1750 only supports asynchronous outputs. However, our compact DSP-3000, DSP-3100, and DSP-3400 FOGs support synchronous outputs.


The super-compact commercial FOG offers revolutionary performance levels for a unit its size, including:

• input rates 5x faster than KVH’s original DSP-1500 FOG
• angle random walk (ARW) 5x better than the DSP-3000 series
• bias stability 8x better than the DSP-3000 series, a level of performance previously only available in larger, more expensive closed-loop fiber optic gyros and ring laser gyros

For complete details, download the detailed datasheet from the commercial or military/government product pages.


Yes, the DSP-1750 is a commercial off the shelf (COTS) product. Please note, however, that the DSP-1750 High variant, which offers input rates as fast as 1000˚/second, is subject to the U.S. Department of Commerce Export Administration Act of 1979.


KVH’s new E•Core ThinFiber is the world’s smallest D-shaped optical fiber - only 170 microns, a 30% reduction from our original E•Core polarization maintaining fiber. It’s an engineering breakthrough that enables the DSP-1750 to deliver a unique combination of both extremely low noise and very high bandwidth.


KVH’s DSP-1750 is a high-performance, super-compact fiber optic gyro (FOG). It is available in both Standard (input rate = 490˚/second) and High (1,000˚/second) variants.* Designed for maximum versatility, it offers both single- and dual-axis configuration as well as optional magnetic shielding.
Its innovative two-piece design – an optical sensor 1.7" in diameter connected to power and processing electronics via a robust interlocking tether – makes the DSP-1750 easy to integrate into platforms where space and payload weight are at a premium while improving accuracy at the same time.

For complete details, download the detailed datasheet from the commercial or military/government product pages.

* Please Note: The DSP-1750 High is controlled by the Export Administration Act of 1979.

Exclusive Technology

  • E•Core ThinFiber
    KVH’s proprietary polarization maintaining E•Core ThinFiber delivers outstanding precision performance in much smaller size gyros, such as the DSP-1750. By reducing the overall diameter of KVH’s standard E•Core fiber to just 170 microns (a 30% reduction!), the resulting E•Core ThinFiber dramatically increases the accuracy of our standard size gyros, and produces small gyros 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 maximum input rate. 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.
