To carry out fixed-depth blast,the principle of inertial measurement was used, accelerometers on the fuse of the earth penetrator collocated,the information of the acceleration and angle velocity of the earth penetrator via the output of the accelerometers obtained,the value of the differential equation got, the direction cosine matrix in real time between the bursts' coordinate and inertial coordinate calculated,and the output data of the accelerometers transformed into the component of acceleration along the inertial coordinate by analyzing the direction cosine matrix.The instantaneous information about the earth penetrator' track was obtained,and the fixed-depth control parameter for fixed-depth fuse was provided.
