Abstract
Abstract Provides a suspension mount for a gyro sensor block suspension eliminates ther cross-talk in a gyro triad having a set of common gyros with the same dither tuned suspension. A sensor block has three gyro mount locations situated such that, when attached, the gyro triad is mutually orthonogal to each other. Two of the gyro mount locations have a spring suspension, each of a different stiffness, formed by joining a central hub, to which the gyro is attached, with the sensor block mass via a plurality of spokes to form a torsional spring about the gyro dither axis.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
69 words
A gyro sensor block suspension comprising a sensor block having tnree gyro mounts for orthogonally mounting a triad of gyros, said gyros each having the same internal dither tuned suspension, two of said gyro mounts having a spring suspension machined into said sensor block, said spring suspensions being of different stiffnesses so as to act in series with said internal dither tuned suspension to reduce the gyro dither frequency.
Claim 2
Dependent Claim
69 words
A gyro sensor block suspension comprising a sensor block having tnree gyro mounts for orthogonally mounting a triad of gyros, said gyros each having the same internal dither tuned suspension, two of said gyro mounts having a spring suspension machined into said sensor block, said spring suspensions being of different stiffnesses so as to act in series with said internal dither tuned suspension to reduce the gyro dither frequency.
Claim 3
Dependent Claim
57 words
A suspension as recited in claim 1 wherein said spring suspension comprises: a central hub to which one of said gyros is attached; and a plurality of spokes integrally connecting said central hub to the main mass of said sensor block such that said spokes form a torsional spring about the dither axis of said one gyro.
