Show affiliationsThe acceleration perturbations of a drag-free satellite with a free-floating spherical proof mass for the LISA space mission to detect gravity waves are presented. These calculations show that the RSS of all disturbances is less than 3.4 × 10−16 m s−2 Hz−1/2. This is about a factor of 10 less than the calculated value for cubical single-axis proof masses and could potentially decrease the low-frequency response correspondingly. The performance calculations presented here have been confirmed by the flight of the DISCOS drag-free satellite.
