(CDA)

An instrument group on the Cassini spacecraft designed to measure dust particles in Saturn's rings. The three CDA instruments are: the precision dust velocity sensor to measure the speed, direction, and charge of a particle; the impact plasma sensor to measure the mass and speed of particles; and the chemical analyser to measure the atomic composition.
