N2 - The heading sensitive drift of platform inertial navigation system varies with the degradation of performance and the coupling characteristics under long-term storage conditions. Such heading sensitive drift is different from those under working conditions, which makes it difficult to analyze the stability for allocating resources for the calibration and maintenance in engineering application. The theory and expression of heading sensitive drift caused by servo loop zero and structure disturbing torque are firstly presented and derived. Secondly, the drift characteristics of influence parameters are analyzed thoroughly, and the integrated behavioral model of heading sensitive drift under servo loop zero and disturbing torque influence is concluded. And then, the long-time drift characteristic, acceleration performance, as well as the stability of heading sensitive drift behavior are analyzed with actual storage condition profile. Results indicate that heading sensitive drift on the X, Y and Z axis has the similar long-term drift characteristics without acceleration response, which is different from the response characteristic in actual use and therefore has great significance for allocating resources for the calibration and maintenance of inertial platform system.
