| Can USD reverse engineer, repair and upgrade legacy systems? |
|
| USD has matched its production capability with a successful repair and upgrade business. We are one of a limited number of organizations designated as a U.S. Government Repair Facility operating under our Air Force repair facility code of EZ7112 and a Navy repair code of Q97469. Through the reverse engineering and manufacturing process, USD has been able to repair or modify many otherwise obsolete products or systems and provide solutions in the event of a Diminishing Manufacturing Sources (DMS). |

| 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.
