This study systematically introduces the development of the world's first full-link and full-system ground demonstration and verification system for the OMEGA space solar power satellite(SSPS).First,the OMEGA 2.0 innovation design was proposed.Second,field-coupling theoretical models of sunlight con-centration,photoelectric conversion,and transmitting antennas were established,and a systematic opti-mization design method was proposed.Third,a beam waveform optimization methodology considering both a high beam collection efficiency and a circular stepped beam shape was proposed.Fourth,a control strategy was developed to control the condenser pointing toward the sun while maintaining the trans-mitting antenna toward the rectenna.Fifth,a high-efficiency heat radiator design method based on bion-ics and topology optimization was proposed.Sixth,a method for improving the rectenna array's reception,rectification,and direct current(DC)power synthesis efficiencies is presented.Seventh,high-precision measurement technology for high-accuracy beam-pointing control was developed.Eighth,a smart mechanical structure was designed and developed.Finally,the developed SSPS ground demonstration and verification system has the capacity for sun tracking,a high concentration ratio,pho-toelectric conversion,microwave conversion and emission,microwave reception,and rectification,and thus satisfactory results were obtained.
