New techneque for multi-missile cooperative localization

One of the key technologies in multi-missile cooperative combat (MCC) is the missile precision positioning technology. In the environment of system-of-systems combat, multi-missile cooperative localization (MCL) based on mutual rangings was proposed to improve the inertial positioning accuracy of the missile community. The cooperative localization system, which is mainly composed of the missile-borne data link and inertial navigation system (INS), was designed and the ranging scheme of the data link as well as the time synchronization problem was analyzed. The weighted rank-defect network adjustment algorithm was applied to estimate the inertial positioning errors. Simulation results show that the method slows down the divergence speed of positioning errors and improves the positioning precision effectively. The positioning precision comes higher with the increase of missiles and it is more than 2 times of the original level when the number of missiles is more than 4.
