摘要
Abstract
Direct-to-cellular satellite system refer to a satellite communication system which allows commercial smartphones to switch seamlessly and imperceptibly for the users between terrestrial mobile networks and satellite communication networks.It has significantly driving force for the innovative development in both aerospace technology and the information industry.Based on three different approaches,including unmodified cellular phones,modified cellular phones and phones with future unified standard,the development of the typical systems is summarized in this paper.Then some of the key technologies in the communication system,satellite system and payload are reviewed from the perspective of the satellite developer.With the review,suggestions for direct-to-cellular system construction and technical research are proposed,which can provide reference for our country to carry out the system construction.关键词
