A two-stage deployment of the petal type antenna for space radio telescope has been proposed. At the first stage, preliminary unstressed low-precision deployment of the antenna has been carried out. At the second stage, high-precision fixation of the final state of open reflector has been realized. To fix the final state of the open antenna self-setting locks have been proposed. Results of computer and physical simulation of the new deployment system have been presented.
