Precision Gyro with Maximum Ease of Integration
Combining 1, 2, or 3 axes of the world’s smallest precision fiber optic gyros (FOGs) within an easy-to-integrate housing, the navigation-grade DSP-1760 provides unmatched versatility to meet the demands of the most challenging design projects. Depending on the application, the end user chooses from six total configurations:
  • 1, 2, or 3 axes of precision FOGs 
  • Either a 15-pin Micro-D connector or a 13-pin circular bayonet connector

The chosen configuration is integrated within an environmentally sealed, lightweight enclosure, ensuring reliability and durability for any installation.

Superior Performance and Quality
A high-bandwidth, low-noise sensor, the DSP-1760 features a solid state design with exceptional performance in bias stability, scale factor, and angle random walk. By using KVH’s exclusive 170-micron E•Core ThinFiber, the world’s smallest D-shaped optical fiber, the DSP-1760 is both extremely accurate and compact, weighing only 0.5 to 0.6 kg (1.1 to 1.3 lbs.), depending on the number of axes.

Stabilization and Navigation Applications
The DSP-1760 is ideal for a wide range of commercial applications, including:
  • Mining automation systems
  • Pipeline inspection robots
  • Platform stabilization for land, sea, and aerial systems
  • Navigation for unmanned and manned systems

A rate gyro does not output accumulated angle. Instead, it outputs rate of change of angle. If the accumulated angle is desired, it would have to be integrated externally.

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.


Yes.  The TracPhone Fleet One uses GPS positioning system by default, but you can select between GPS, Beidou (Chinese satellite navigation system), GPS and Beidou and GPS and GLONASS (Global Navigation Satellite System).

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, the resulting E•Core ThinFiber dramatically increases the accuracy of our standard size gyros, and produces 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 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.
