Abstract:The BeiDou-3 Navigation Satellite System (BDS-3) was formally commissioned and operational on July 31, 2020, which provides new opportunities and energy for development of Beidou industrialization. How to make good use of BDS and maximize application efficiency is a research hot spot in the field of BDS application. Aimed at meeting the application requirements of industry users for BDS terminal software, the key technologies such as formatted message service, virtualized dynamic networking, multimedia compression and reconstruction, and long message adaptive transmission were studied, and then a new BDS-3 terminal software was designed and developed. The terminal software can be used in typical scenarios of national defense and military, disaster relief and reduction, and eco-environmental protection. The practical application shows that the BDS-3 terminal software can realize high-efficiency multimedia data transmission such as formatted short message, voice, image and long message, and meet the needs of dynamic networking and information sharing among users. This is great significance for enriching BDS application scenarios and promoting the development of BDS industrialization.
