This paper reviews the advances that have taken place in strapdown sensor technology since 1978. It is intended as an update to the paper on Strapdown Sensors presented as part of AGARD Lecture Series 95 in 1978. Principal areas addressed in strapdown gyro technology are the state-of-the-art in mainstream floated rate-integrating and tuned-rotor strapdown gyros, performance advances in laser gyros, special design considerations associated with mechanically dithered laser gyros, the state-of-the-art in magnetic mirror and multioscillator laser gyros, present and projected application areas for laser gyros related to size, performance and cost, the theory of operation and state-of-the-art in fiber-optic rate sensor. Basic areas addressed in strapdown accelerometer technology are performance advances in pendulous accelerometers, and the theory of operation and state-of-the-art in vibrating beam accelerometer technology.
