Abstract

The dynamically tuned gyroscope (DTG) has been marketed primarily as a low-cost, small-package, two-axis rate sensors for tactical missiles and is used widely in this application. The DTG is also suitable for application to stabilized electro-optical sights, though little appears in the literature on this subject. At first glance, this gyro appears to be controllable with the same capture-loop technology used for the once-ubiquitous single-axis rate- integrating gyro. Subtle but very important distinctions exist however, and inattention to these differences can result in poor or disastrous gyro performance. These and other issues pertaining to use of the DTG in sight stabilization systems are discussed. Topics covered include theory of operation, interface electronics, capture-loop design, and a discussion of error sources typically found in electro-optical systems.
