Description
Watson Industries has been designing and making solid-state gyros since 1980. They now provide a new series of rate gyros, the MaxGyro®. This breakthrough new gyro is built, using a monolithic three-dimensional tuning fork resonator, to be a VSG replacement and much more. Based on proven technology, this gyro is built with new features including built-in test.
The MaxGyro® has best-in-class performance for stability, acceleration insensitivity, low mounting sensitivity and excellent vibration rejection. This is achieved by having a much larger sensing element that is solidly mounted. The larger element allows better relative tolerances for tuning and better signal to noise performance. Solid mounting holds the gyro sensing element in a stable alignment. In contrast, all the competitive MEMS gyros use sensing elements that are supported by thin filaments as springs that are resonant at disturbingly low frequencies. These springs allow the sensing element to shift and resonate under shock and vibration, which affects their performance significantly.
