GO methodology is a success-oriented system reliability analysis technique,which can analyze and assess the reliability of multi-state,related-time,complicated systems. This is the first attempt to apply GO methodology in the reliability analysis of Inertial Navigation System( INS). GO probability formula algorithm and comparison with Fault Tree Analysis( FTA) method are used. Concrete steps of GO methodology are discussed,GO model of INS is built,and the quantification calculations are processed using probability formula algorithm in GO methodology. Besides,primary discussion for signal feedback is progressed and a solution is provided. Finally,through the comparison of the results of the GO and FTA method,it proves that the application of GO methodology in INS is valid and feasible.
