Abstract: The tracking producer software package is very important in the inertial navigation research period. In this paper, the whole design thought of tracking producer software package is introduced, and track equation and its control equation are detailed. Then the paper describes the regulation of plane body’s position, velocity, attitude, force and absolute angle velocity. In addition, control regulation is analyzed which is under the condition of straightaway, rolling, turning, sinusoidal flying state. Finally, it is simulated what tracking producer exports while the plane body flies and rolls along its symmetrical axis. The simulation results show that the design of the tracking producer package is correct, which is true of all kinds of the plane body’s actual states.
