DSP-3000 Fiber Optic Gyro (FOG) (Non-ITAR) Improved Specification

Superior Precision and Reliable Performance at a Lower Cost

The workhorse of EMCORE’s single-axis FOG series, EMCORE’s DSP-3000 offers field-proven performance in a wide range of applications. Its compact and robust design, coupled with a choice of analog, digital, and digital RS-232 outputs, makes the DSP-3000 the most versatile fiber optic gyro available and an ideal solution for guidance and stabilization, low-cost IMUs, integrated GPS/INS, and AHRS.


  • EMCORE’s mature all-fiber optical circuit for exceptionally low noise (ARW)
  • EMCORE’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

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

*This product is covered by one or more patents, including U.S. Patent #6,429,939, “DSP Signal Processing for Open Loop Fiber Optic Sensors.”

Feature Options

Two Versatile Variants

  • If you need a compact FOG with a powerful high-speed RS-422 interface with 1000 Hz asynchronous output, consider the DSP-3100 FOG.
  • If you require a true RS-422 interface and a 1000 Hz synchronous output in a durable, shielded package, take a look at the DSP-3400.
