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 and enhanced EMI/RFI protection.
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.
