Inertial navigation performance of an interferometric fiber optic gyro has been demonstrated over extended environments.
Feb 1, 1992
Discusses the optical phenomenon (SAGNAC effect) at the core of the RLG and FOG and demonstrates how the rate integrating characteristic can be achieved with the IFOG.
High performance guided-wave optical components are essential to fiber optic gyros (FOGs).
Feb 1, 1991
The paper examines the current status of Litton's design approach to the attitude-and-heading reference system interferometric fiber-optic gyro (IFOG).
Jan 1, 1967
A examination of two major innovations in military aeronautics--turbojet propulsion and the variable-sweep wing--using the classical economic investment model. Three phases of the innovation process are distinguished: invention or conception, demons...

Jan 9, 1956
A discussion of a single-degree-of-freedom motion of a rigid right circular cylinder (i.e., rotation about any axis normal to the longitudinal axis).
Mar 25, 1954
A theoretical study of optimum determination of position by a navigation device employing independent inertial and velocity measurements, which are subject to random errors.
Aug 1, 1953
A 1953 RAND study that investigates the problem of prediction of airplane drag divergence Mach number and provides an empirically determined expression that is applicable to clean airplane configurations.
