Abstract:
A carrier should be used a guidance system for reaching to the point of injection in an orbit. The main purpose of guidance system in the injection process is issuance of guidance commands to achieve the final desirable velocity and position. These velocity and position indicate the purpose orbit for injection. Carrier is a dynamic system which is described by mathematical terms. In general carrier guidance systems apply pitch angle or rate of pitch angle to reach specific path over injection process. Different methods are available for carrier guidance such that preset method. In this method, the guidance system addresses specific guidance commands and control system performs these commands to achieve specific path. This method operates as an open loop controller and it cannot respond to disturbances in path. In this project we improve an active guidance using of evolutionary algorithm and neural network. This method as for disturbances and deviations produces guidance commands and therefore generate new path for orbit injection problem
