1. A two degree of freedom rate gyroscope comprising:

  • (a) a housing;

    (b) a rotatable mass disposed within said housing;

    said mass having a longitudinal spin axis and two input angular rate axes mutually orthogonal to said spin axis;

    (c) said rotatable mass comprising a rotor and a rotating drum;

    (d) said rotating drum being flexibly coupled to said rotor by suspension means;

    (e) said suspension means comprising diametrically extending sets of elastic arms;

    one set of said arms being disposed orthogonally to a second set of such arms;

    said elastic arms having a predetermined elasticity sufficient to restrain the precession of the mass in response to angular rates about the two input angular rate axes such that the mass achieves an angular orientation about a pair of output axes proportional to the magnitude of such angular rates.
