`
`Description:
`Introducing the ADS-C232-1AD, Watson
`Industries newest sensor system! It is a much
`smaller, yet fully functional vertical reference
`system that can serve as a replacement for a
`Watson VRS in many applications.
`
`The Watson Industries Dual Axis Vertical
`Reference System is a solid-state gyro package
`that measures angular displacement and rate,
`especially where dynamic motion may
`interfere. Under these conditions, the effects
`of lateral accelerations severely limit the
`performance of an ordinary accelerometer or
`pendulous device.
`
`
`
`Dual Axis Vertical
`Reference System
`
`ADS-C232-1AD
`
`
`
`The Watson Dual Axis Vertical Reference achieves exceptional performance by integrating the output
`of a vibrating structure gyro to get an estimate of the attitude, which is then compared to accelerometers
`to find the error. The error is filtered over a long time constant and subtracted from the rate gyro output
`to correct biases in a closed loop error correction system. This process lets the gyro measure short-term
`attitude accuracy above the correction loop frequency while the accelerometer serves as the long-term
`reference.
`
`The ADS can be a functional replacement for mechanical gyros, which are often more expensive, larger,
`heavier and less reliable than this solid-state sensor. It is especially suited for applications where there is
`limited bank and elevation such as ships, underwater vehicles, some land vehicles, and certain camera
`applications.
