The suspended spinning wheel gyroscope has a potential advantage of high precision;in addition,it can survey 2 axes of angular rate and 3 axes of acceleration simultaneously.Two kinds of gyroscopes exist,which are electrostatically suspended spinning wheel gyroscopes and magnetically suspended spinning wheel gyroscopes.In this paper,the respective characteristics of various structures,operating principles,fabrication processes and performances of magnetically suspended gyroscope developed in the world are s...
