Design of mobile communication terminal supporting multiple orbital altitude satellites
Satellite mobile communication has the advantages of wide coverage,long transmission distance,and being unaffected by terrain,and has been rapidly developed and widely applied.Communication terminals are an important component of the satellite communication system,providing users with various services such as voice and data through wireless link interaction with satellites and ground stations.This article presents a broadband terminal design and implementation scheme suitable for high orbit and low orbit satellites.The design of the terminal is elaborated in detail from hardware,software and process aspects,and the function and performance of the terminal are verified through system integration testing.The terminal design adopts ideas such as hardware modularization,software componentization,and interface standardization,and is divided into different layers according to functions,making it easy to independently implement,upgrade,and expand.
