One Research on Fault Diagnosis Method of Aircraft Inertial Navigation System

This paper analyses the fault diagnosis of hardware and software of some aircraft inertial navigation system, designs relevant diagnosis project of hardware and software fault, especially studies and deduces diagnosis formula and method when one of four level gates of inertial navigation main and standby platform system appears slow excursion. The experiment proves the following: This method can achieve fast fault orientation, its process of analysis and deduction is in accordance with reality of some aircraft inertial navigation manufactures, and it has very important reference value to inertial navigation fault diagnosis.
