1. A gyroscope comprising:
- a case;
mechanically balanced gimbal means having lower and upper surfaces;
means for suspending said gimbal means from said case;
a spin motor, coupled to said lower surface of said gimbal means, having a wheel coupled thereto for spinning about a vertical axis, andmeans, coupled to said upper surface of said gimbal means, for measuring positions of said gimbal means with respect to said case and for providing torque to said gimbal means to precess said wheel, said measuring and torqueing means including;
a plurality of pickoff and torquer coil pairs disposed along orthogonal axes of said measuring and torqueing means; and
a plurality of plates, having magnets disposed therebetween coupled to said upper surface of said gimbal in a cooperating relationship with said pickoff and torquer coil pairs.

Abstract
In an azimuth determining gyroscope, a mechanically balanced gimbal is suspended from a fixed case by a wire which passes through the generally tubular upper portion of the suspended gimbal. A spin motor and a wheel for rotating about a vertical axis are coupled to the lower portion of the suspended gimbal. The upper portion of the suspended gimbal has pickoff and torquer coils for measuring the position of the suspended gimbal with respect to the fixed case and for providing torque to the suspended gimbal. Leads to the spin motor are configured to act as azimuth restraint means between the suspended gimbal and the fixed case.
