Vertical Reference ADS-C132-1AD (Single Axis)

Description

Introducing the ADS-C132-1AD, 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 Single 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.

The Watson Single 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.
