In recent years,the field of satellite communication has developed rapidly,and the booming market demand has given rise to various types of satellite terminals. Satellite directly connected mobile phones have become a highly anticipated product type due to excellent communication performance and portable usage scenarios. Starting from the development of satellite communication industry at home and abroad,this article sorts out the technical route and application scenarios of satellite direct connected mobile phones,and prospects the evolution process of multi-mode mobile phones in the sky and earth based on chip technology architecture. It proposes that multi-mode satellite direct connected mobile phones that integrate chip integration solutions are the development direction of satellite terminals. At the same time,the challenges faced by multi-mode terminals are analyzed from the aspects of spectrum,the power consumption,the cost,and the technical system,and the development direction of satellite direct connected mobile phone terminals is predicted.
