A BRIEF REVIEW ON THE DEVELOPMENT AND THEORY OF NON-GYROS INERTIAL MEASUREMENT UNIT

In view of the importance of non-gyros Inertial Mea surement Unit(NGIMU) for inertial navigation system, the origin and current status of NGIMU are summarized. Three configurati ons of linear accelerometers and the problems of their mathematic models are reviewed, with emphasis on the f uture research.
