Vibrating String Accelerometer
The Vibrating String Accelerometer (VSA) at the heart of the Apollo Traverse Gravimeter Experimeter
An instrument for detecting small variations in the gravitational field of the Earth or other body, frequently used in mineral and oil prospecting, and in planetary exploration. Variations in the gravitational force on a mass suspended from a spring cause it to stretch or be deflected in a way which is then measured. See also accelerometer.
