Gradient methods for trajectory control of aircraft in a two-stage passive guidance system air-launched with increased accuracy of the positioning of radio sources

The article presents the results of the development of algorithms for trajectory control aircraft information support to ensure the lowest possible error in determining the location of the target at any given time. Emphasis is placed on the gradient me-thod and the gradient projection method. Algorithm for trajectory control plane information support, developed on the basis of the gradient method to minimize the objective function allows bi-goniometric guidance system to get the highest decrease of the mean square error positioning radio-emitting target. Algorithm for trajectory control plane information support using gradient projection method improves the efficiency of combat employment goniometric bi-guidance system, preventing the entry of the aircraft into the danger zone. For situations when you must first perform the trajectory control both positions aimed at ensuring the highest accuracy positioning and motion parameters of Iran, and only then solve the problem of guidance, it is suggested to use the gradient projection method developed that will allow not only the trajectory control supervision, but prevent the occurrence of aircraft in flight exclusion zones.
