The launch of Tiantong-1 01 star is just the beginning of China's satellite mobile system. According to the plan, the 02 and 03 stars of Tiantong One will gradually evolve, adopting the new Dongfanghong-5 satellite platform to increase the power and antenna aperture of the whole star, and support broadband communication with greater capacity. After launching, it will be deployed on the east and west sides of the 02 star to form normalized coverage of the central and eastern Pacific Ocean, the Indian Ocean and the “Belt and Road” region. With the development and construction to be completed and subsequent application and promotion, it is believed that the Tiantong-1 satellite mobile system will play an important role in improving China's mobile communications and emergency communications security level, and become an indispensable information foundation for economic construction and national defense construction. Facilities to meet the needs of users in government, military, industry, and the public. It can be predicted that by 2025, the number of end users of mobile communication satellite systems will exceed 3 million. Users can rely on satellite mobile systems for personal communications, ocean transportation, ocean fishing, air passenger transportation, bipolar expeditions, and international peacekeeping. CONQUEST S18 Tiantong satellite mobile phone can not only support confidential voice communication, data transmission and video conference, realize disaster rescue, maritime rescue and remote area rescue, carry out remote education, telemedicine, broadcasting and live broadcast services, but also provide scientific research, High-end commercial users such as exploration provide services such as Internet access and personal mobile communications.
In other words, on the one hand, the satellite mobile system can ensure communication without terrestrial communication, and on the other hand, it can implement the query of the location of the terminal.
