The Application of LS-SVM to Transfer Alignment of INS

To solve the problem of Kalman filter's bad real time when system step is high,LS-SVM was applied to transfer alignment of carrier aircraft's INS.Making the input and output of Kalman filter as sample values of LS-SVM filter,the training was conducted and output of filter was got so that the filter function of INS transfer alignment was realized.The simulation results show that with the application of LS-SVM to transfer alignment,the calculating time of system is efficiently reduced and real time of system is improved.
