Post-voting true attack angle and sideslip angle filtering method and system

The invention belongs to the technical field of flight navigation, and particularly relates to a voted true attack angle and sideslip angle filtering method and system. The method comprises the following steps: S1, obtaining a voted true attack angle and a voted sideslip angle to form a current input value; s2, acquiring a true attack angle and a sideslip angle after the voting of the last beat to form a last beat input value, and acquiring a true attack angle and a sideslip angle after the filtering of the last beat to form a last beat output value; s3, the current input value is filtered through a filtering formula, a current output value is obtained, and the filtering formula is shown in the specification, x is the current input value, y is the current output value, x-1 is the last-beat input value, and y-1 is the last-beat output value. According to the method, the problem of velocity vector character jump caused by the voted true attack angle and the voted sideslip angle is solved. 本申请属于飞行导航技术领域，特别涉及一种表决
