Software rate gyro worked out the aeroplane angular velocity with the mathematical methods that includes numerical value differential coefficient and coordinate conversion about the aeroplane flight pose angle,then,the paper analyses the caculation formula of angular rate,software precompiler of the signal converter circuit of attitude angle and the computer processing and so on. Software rate gyroscope had more advantages than hardware gyroscope over many aspects,such as breakdown rate,maintenance,life-span,volume,weight,achievement to consume and so on. Thereby the velocity measurement redundancy and its reliability will increase.
