DSP-3400 Fiber Optic Gyro

Robust, Reliable Gyro in a Durable, Shielded Package

The KVH DSP-3400 offers the reliability and robust design found in all members of the DSP-3000 series but adds the benefits of a true digital RS-422 interface and a 1000 Hz synchronous output in a durable, shielded package. As a result, the DSP-3400, with its robust, modular design, is a powerful option for use in applications requiring FOG output to be transmitted over a longer distance. Features:

  • KVH’s mature all-fiber optical circuit ensures exceptionally low noise (ARW)
  • KVH’s proprietary E•Core polarization-maintaining fiber
  • Robust, modular design housed in a package roughly the same size as a deck of playing cards

Technology Details

Exclusive Technology

DSP Technology

KVH’s DSP electronics improve FOG performance in critical areas such as scale factor and bias vs. temperature, scale factor linearity, and maximum input rate. KVH’s exclusive DSP design overcomes the limitations of analog signal processing, eliminating temperature-sensitive drift and rotation errors.
