新华社西昌4月1日电（李国利、钱铃奇）3月31日23时51分，我国在西昌卫星发射中心用长征三号乙运载火箭，将天链二号01星送入太空，卫星成功进入地球同步轨道。
天链二号01星是我国第二代数据中继卫星系统的第一颗卫星，将为载人航天器、卫星、运载火箭以及非航天器用户提供数据中继、测控和传输等服务。
据了解，天链二号中继卫星系统在任务规划、系统管理、业务运行上相比天链一号中继卫星系统取得显著进步，数据传输速率和多目标服务能力也有较大提升，将对提高中低轨卫星、载人航天器信息回传时效性、在轨运行安全性和任务实施灵活性发挥重要作用。

(Technology) (1) China successfully launched the second generation of data relay satellite system
At 23:51 on March 31, China used the Long March 3B carrier rocket at the Xichang Satellite Launch Center to send the 01 chain of Tianlian 2 into space, and the satellite successfully entered the geosynchronous orbit. Xinhua News Agency (photo by Guo Wenbin)
Xinhua News Agency, Xichang, April 1 (Li Guoli, Qian Lingqi) At 23:51 on March 31, China used the Long March 3 B carrier rocket at the Xichang Satellite Launch Center to send the 01 chain of Tianlian 2 into space. Successfully entered the geosynchronous orbit.
Tianlian No.2 01 is the first satellite of China's second-generation data relay satellite system. It will provide data relay, measurement and control and transmission services for manned spacecraft, satellite, launch vehicle and non-spacecraft users.
It is understood that Tianlian No. 2 relay satellite system has made significant progress in mission planning, system management and business operation compared to the Tianlian No. 1 relay satellite system, and the data transmission rate and multi-target service capability have also been greatly improved. It is important to improve the timeliness of information return for low- and low-orbit satellites, manned spacecraft, on-orbit operational safety and task implementation flexibility.

The Tianxing 2nd 01 star and the Long March 3B carrier rocket were developed by China Aerospace Science and Technology Corporation and China Academy of Launch Vehicle Technology.
This mission is the 301st flight of the Long March series of launch vehicles.
