Description

The Watson vertical reference is a solid state gyro system used to measure angular displacement and rate, especially where dynamic motion may interfere. This is where the effects of lateral acceleration severely limit performance capability of an ordinary accelerometer or pendulous device. The Watson vertical reference provides exceptional performance in this area.

This vertical reference achieves improved performance by integrating a Watson angular rate gyro to get an estimate of attitude and then comparing it with the output from an inclinometer (pendulum) to find the error. The error is filtered over a long time constant and subtracted from the rate gyro output to correct biases as a closed loop error correction system. The Watson vertical reference can be a functional replacement for a mechanical vertical gyro. Mechanical gyros are often more expensive and cannot provide the reliability and life of this solid-state sensor.

The Watson vertical reference has been used to stabilize or control ships and submersibles, to instrument automobiles, to stabilize antennas and many other applications. This vertical reference is especially suited for applications where there is limited bank and elevation such as ships, underwater vehicles, land vehicles, and camera stabilization. This is because the vertical reference uses a linear coordinate system. To do any better, a full three axis system would be required. Consult the factory about your application.
