Overview
The DSP-3000 uses EMCORE’s patented Digital Signal Processing (DSP) electronics. EMCORE’s breakthrough DSP design overcomes the limitations of analog signal processing, virtually eliminating temperature-sensitive drift and rotation errors. In addition, EMCORE’s DSP technology offers significant performance improvements in such critical areas as scale factor and bias stability, scale factor linearity, turn-on to turn-on repeatability, and maximum input rate. Exceptional low noise (ARW), insensitivity to cross-axis error, and shock and vibration robustness make the DSP-3000 a perfect fit for demanding industrial applications.
This performance, combined with the inherent simplicity and reliability of our mature all-fiber optical circuit, establish the DSP-3000 as an outstanding and affordable solution for motion sensing, stabilization, navigation, and precision pointing applications.
Fabricated from EMCORE’s proprietary E-Core® polarization maintaining fiber, the EMCORE DSP-3000 delivers superior precision and reliable performance at a lower cost than other comparable fiber optic and mechanical gyroscopes. Its temperature stability and repeatability make it particularly wellsuited for precision stabilization, GPS integration, and multi-axis tactical-grade inertial measurement systems.
The noise spectrum of the DSP-3000 is exceptionally flat, lacking the discrete noise components of mechanical gyros. With no moving parts to maintain or replace, the DSP-3000 lasts longer, functions better, and yields significant product life cycle
savings.

Available Configurations
The DSP-3000 series comes in three variations:
- If you require a compact FOG with a choice of analog, digital, and digital RS-232 outputs, consider the DSP-3000 FOG.
- 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 FOG
