A gyroscope comprising: a frame; a tuning fork comprising a base and first and second prongs, wherein the base has proximal and distal ends, and wherein the proximal end is coupled to the frame and the distal end is coupled to the first and second prongs; first and second drivers configured to drive the first and second prongs respectively to oscillate with respect to the frame in a first direction, such that the prongs oscillate at their respective resonant frequencies and 180° out of phase with each other; and at least two digital position triggers operatively coupled to the frame and to the tuning fork, wherein each position trigger is configured to experience at least two trigger events during each oscillation of the tuning fork in a second direction, wherein the second direction is orthogonal to the first direction. |
