Evaluation of attitude and acceleration sensors for marine applications / by J.M. Preston. : DR52-11/9-1990E-PDF

"A wide variety of instruments are available for measuring the attitude and accelerations of a marine vehicle, with characteristic advantages and limitations. The apparatus described here was built to evaluate such sensors against accurately measured accelerations and attitudes. It resembles a small Ferris wheel, and moves the sensor on 1.5-m diameter circles, on a support which remains horizontal, at selectable frequencies similar to those of ocean waves. The sensor can be yawed or pitched, asynchronously with the rotation. The acceleration and attitude of the sensor can be calculated from the shaft encoders on the rotation and yaw/pitch axles. Results are given for two inclinometers, an accelerometer, a piezoelectric angular-rate sensor, and a gyroscopically stabilized accelerometer package."--abstract (page iii).
