1.2 Product Description
The DSP-3000 is a single-axis interferometric fiber optic gyro for use in a wide range of
applications, including antenna and optical stabilization, navigation, positioning,
aerospace (AHRS), IMUs, robotics, and instrumentation. Based on proprietary
polarization-maintaining fiber and precision FOG technology, the DSP-3000 employs a
digital signal processor and an all-fiber, open loop optical circuit. The gyro measures
angular rate of rotation, which can be integrated to allow turning angle to be measured
accurately. Operating from a nominal 5 VDC, it outputs a digital or analog message with
input rates of up to ±375 degrees per second for digital versions, or ±100 degrees per
second for the analog version. The DSP-3000 is self-initializing and ready for use
approximately 5 seconds after power is applied.
