SDD3000 Single-Axis Precision Digital Gyroscope (Non-ITAR)

Systron Donner Quartz MEMS
The SDD3000 is our high performance, digital, single-axis gyroscope. Incorporating an advanced Quartz MEMS sensing element, it is optimized for applications that require low noise and excellent stability over changes in temperature and through vibration. Our proprietary Quartz MEMS technology delivers high reliability and a low total cost of ownership, with no wear-out modes or required calibration intervals. Boasting a small size, light weight and very low power consumption, the SDD3000 is truly a leader in its performance class.

The SDD3000 combines our most advanced sensing element with state-of-the-art digital signal processing (DSP) technology, yielding superior performance through even the most demanding conditions. Delivering unprecedented low Angle Random Walk values (output noise) and class-leading stability among MEMS gyros, the SDD3000 is an ideal solution for stabilization, precision pointing applications, instrumentation, motion sensing and GPS/AHRS integrations.

The SDD3000 outputs angular rate and BIT data continuously upon the application of power, with no user input or start command required. Offered with two standard connection protocols (RS-232 or RS-422) and data rates (600 HZ or 100 Hz), the SDD3000 can be easily integrated into any system. Excellent stability over temperature and turn-on-to-turn-on bias repeatability over extended periods of use make the SDD3000 particularly well-suited for many stabilization and instrumentation roles.
