What new changes will satellite direct connection bring?

Satellite communication is accelerating its entry into the lives of ordinary people. Satellite communication has always been applied in special fields such as navigation, aviation, emergency rescue, and field operations. In recent years, with the accelerated development of information and communication technology, the application scenarios of "satellite direct connection" have become increasingly diverse and have begun to expand into the mass market. With the comprehensive construction of low orbit satellite constellations and the rise of the satellite data consumption market, the aerospace information industry, which integrates cutting-edge technologies such as artificial intelligence, big data, and cloud computing, is accelerating the change in people's lives. "In its recent semi annual report, China Eastern Red Satellite Co., Ltd. stated that artificial intelligence technology represented by computer vision continues to break through, promoting the acceleration of intelligent, real-time, and precise development in multiple industries such as ecological environmental protection, disaster prevention and reduction, and agricultural planting, becoming a new engine for innovative development of satellite applications.
