How do micomachined quartz rate sensors compare to other gyroscope technologies that are currently available?
SDI’s innovative solid-state gyroscopes utilize a one-piece sensing element which is micromachined from pure crystalline quartz. Unlike traditional mechanical gyroscopes which are mechanically complex, contain hundreds of individual precision parts, and have a limited life, SDI’s quartz sensors feature a monolithic sensing element with no known modes of wearout. SDI quartz gyroscopes have many advantages over other solid-state gyroscope technologies. First, their construction is extremely simple…the sensing element is just one piece! Fiber Optic Gyroscopes (FOG) and Ring Laser Gyroscopes (RLG) tend to be much more complex, time consuming to build, and considerably more expensive. The sensing elements of SDI’s quartz gyroscopes can be mass produced at a very low recurring cost using methods similar to those employed to fabricate millions of quartz references for watches each year.
