Design of Geographic Information Data Transmission System Based on Satellite Communication

In response to the new demand for geographic information transmission, this article designs and implements a geographic information data transmission system based on satellite communication, which mainly consists of two parts: a data transmission module and a satellite communication transmission module. The data transmission module can complete functions such as data reception, data transmission, data forward processing, data reverse processing, and network transmission. The satellite communication transmission module can complete network security encryption transmission, ensure network security and achieve point-to-point communication. Key issues such as data compression, data encryption, data watermarking and integrity authentication have been focused on, providing new means for remote real-time transmission of a large amount of geographic information data and a good teaching and training platform for professional course practice.
