The invention is a suspension system for a two-degree-of freedom flexure-suspended free-rotor gyroscope and a miniature gyroscope incorporating such a flexure system. An axial strut suspension device for controlling the axial position of the rotor includes a series of thin, flat sections, while the radial suspension function is performed by a cross-shaped element of very thin metal, one pair of the diametrically opposed cross ends thereof being affixed to the rotor-driving shaft, while the other pair of opposed cross ends thereof is affixed to the gyroscope rotor.
