In view of the accumulation of errors produced by gyroscope and the interference of digital magnetic compass(DMC),in order to enhance the accuracy of navigation with low cost,the program of gyroscope integrated with DMC is designed.A robust compensation filter is designed to inhibit low-frequency interference of DMC and to improve the accuracy of information integration.Simulation with gyroscope and DMC show that high-frequency interference and the accumulation of errors can be inhibited by compensation filter,in addition to the high-frequency interference and the accumulation of errors,low-frequency interference for long time can also be inhibited by the robust compensation filter,which is proofed as simple and reliable methods.
