At 12:25 a.m. on January 20, China successfully launched the Tiantong 1-03 satellite with the Long March 3B carrier rocket at the Xichang Satellite Launch Center. The satellite successfully entered the scheduled orbit and the launch mission was a complete success, which spells a good start for China’s space launch in 2021.
This is also another successful application of DHU’s scientific research achievements after assisting the launch of Tiantong 1-01 and Tiantong 1-02. The technology of high-precision metal mesh reflector developed by the high-performance fiber special weaving team of the College of Textiles of DHU is one of the key technologies adopted by the whole satellite system, as well as a common technical concern in today’s international aerospace industry. Based on the products developed in the early stage, the project team has gone through numerous failures and developed a high-precision satellite-bone antenna reflector with independent intellectual property rights, which meets the requirements of the mission of satellite launching.
Tiantong 1 satellite mobile communication system, independently researched, developed and constructed by China, is a satellite mobile communication system and composed of a space segment, ground segment and user terminal. The general research and development of Tiantong1-03 satellite was laid out by the China Academy of Space Technology. After being launched into orbit, it will form an integrated world-earth mobile communication network with the ground mobile communication system. It will provide all-weather, all-time, stable and reliable mobile communication services such as voice, short message and data for users in China and its surrounding areas, the Middle East, Africa, and other relevant regions as well as most sea users of the Pacific Ocean and the Indian Ocean.
