Our solutions cover three major application scenarios: satellite Internet of Things, satellite Internet and satellite emergency communication. The Internet of Things solution takes the Internet of Things equipment, satellite communication equipment and satellite hub cloud monitoring platform as the core, and combines high/low orbit satellites and ground networks to build a "heaven and earth" Internet of Things system to achieve real-time data reporting and analysis. Internet solutions integrate satellite resources, gateway station construction, satellite terminals and application terminals through satellite broadband products, and cooperate with operators to build an integrated information service platform of "land, sea, air and sky". The converged communication system is the core of the emergency communication solution, which combines multiple communication networks, multiple services, and multiple terminals to realize rapid networking, and supports multi-level linkage and command scheduling at the emergency scene, front, and rear commands to improve emergency response efficiency.
