- In this paper, fault detection and isolation algorithm for inertial sensor system is
proposed. To identify the inertial sensor fault, single antenna GPS receiver is used as an
effective redundancy source. To use GPS receiver as redundancy for the inertial sensors,
the algorithm to estimate the attitude and acceleration using single antenna GPS receiver
is adopted. Using Doppler shift of carrier phase signal and kinetic characteristics of
aircraft, attitude information of aircraft can be obtained through one GPS antenna at the
coordinated flight condition. Based on this idea, fault diagnosis algorithm for inertial
sensors using single antenna GPS based attitude is proposed. For more effective FDI,
decision variable considering aircraft maneuver is considered. The effectiveness of the
proposed algorithm is verified through the numerical simulations for the various cases.
