Abstract Trajectory optimization has been usually performed to determine the thrust attitude profile for a launch vehicle during the powered flight for the orbit insertion of a satellite. However, mere following such an optimized thrust attitude profile does not be guarantee thee exact orbit insertion due to uncertainties included in the launch vehicle and the environment. In this paper, an explicit guidance scheme for a upper stage is presented for exact orbit insertion of payload. The proposed guidance scheme separately produces the guidance in the vertical and the horizontal channel. A difference between desired altitude and current altitude is reduced by the vertical guidance command and a difference between desired inclination and current inclination is reduced by the horizontal guidance command.
Keywords orbit insertion,upper stage, closed-loop guidance
