What is the difference between a Rate Gyro and an Integrating Gyro?
Rate Gyro:
A rate gyro is generally a single-degree-of-freedom gyro having primarily elastic restraint of the spin axis about the output axis. In this gyro an output signal is produced by precession of the gimbal, which is proportional to the angular rate of the case about the input axis.

Rate Integrating Gyro:
A rate integrating gyro is generally a single-degree-of-freedom gyro having primarily viscous restraint of the spin axis about the output axis. In this gyro an output signal is produced by precession of the gimbal, which is proportional to the integral of the angular rate of the case about the input axis.

Precession:
Precession is a rotation of the spin axis produced by a torque, T, applied about an axis mutually perpendicular to the spin axis and the axis of the resulting rotation. A constant precession rate, , is related to rotor angular momentum, H, and applied torque, T, by the equation T = H.
 
Is USD classified as a small business?
USD is classified as a small business concern and our Government Manufactures code (CAGE Code) is 26269.
