Embodiment
[0041] Example: such as Figure 5As shown, in the laboratory environment, the slewing motion of the ship is simulated, and the simulation experiment of two gyro compass faults is carried out for the heading system, and the above steps are used for data processing. The result is as Figure 5 d is the fusion output data, Figure 5 a. Figure 5 b. Figure 5 c is the measurement data of gyrocompass 1.
[0042] The invention can ensure the accuracy of fault judgment due to the adoption of improved weighting algorithm and multi-level fault judgment mechanism, and has the advantages of small measurement error, strong adjustment ability, real-time performance and ease of use.
