my country's establishment of the second -generation Earth Synchronous Rail Data Reinforcement Satellite System

Xinhua News Agency, Beijing, July 13 (Reporter Hu Yan, Song Chen) In the early morning of July 13, the Long March 3 B Rocket Rockets Rolling Tianchain 2 of the Territory No. 2 Star in the First House of China Aerospace Technology Group Co., Ltd. The Xichang Satellite Launch Center ignited and lifts off, and the satellite was precisely sent to the scheduled track, and the launch task was successful. my country's second -generation Earth synchronous orbit data relay satellite system is formally completed, and the capacity of Tianji measurement and control and data relay has been greatly improved.

Tianchang No. 2 Star was developed by the Fifth Hospital of Aerospace Science and Technology Group. It is the second -generation Earth synchronous track data relay satellite. After the star enters the track and completes the test, it will operate global networking with the Tianchain No. 2 Star and 02 Star.

The successful development of Tianchang No. 2 Star has verified the ability of Tianchang No. 2 satellite to develop rapidly, providing support for subsequent multi -stars quickly on the rail network network, further accelerating the pace of my country's Tianji testing and transmission network construction.

The full name of the relay satellite is to track and data relay satellites, which is equivalent to a data transit station in the sky. It can provide data relay and measurement and control services for satellites and spacecraft, which can greatly improve the benefits and emergency capabilities of various satellites. And can reduce the number of ground stations and measured boats, known as the "satellite satellite".

The main task of my country's Tianchain Zhongjie Satellite is to provide data relay and measurement and control services for manned spacecraft such as spacecraft, space laboratory, space station, etc., such as the communications of important tasks such as Tiandi Calls, Space Lessons, Meeting and Mission, and Card out of the cabin. It is based on the main satellite of the Sky Chain.

At present, my country has successfully developed two generations of earth synchronous orbit data relay system. The first generation has successfully launched the five satellites 01 to 05, and the second generation has successfully launched the three satellites of Tianchain 2 01 to 03.

According to reports, compared with the Tianchang No. 1 satellite public platform, Tianchain No. 2 is developed by Dongfanghong No. 4 public platform. Among them, the Star Room Blind antenna has broken through a large number of problems, which has doubled the number of user target services, and the service efficiency has increased significantly.

The Shenzhou No. 14 manned spacecraft launched in June this year flew to space with three astronauts and opened the 6 -month -old station. During this period, the two generations of Sky Chain Satellite System built a piece of information "Tianlu" for space stations and ground stations around the weather to escort the lives and work of astronauts. The use of the two sets of global relay satellite systems will greatly improve the reliability and security of information transmission.

This launch is the 426th launch of the Long March series of launch vehicles. The technical status of the Long March III Rockets of the Long March 3 of the task is generally stable. At the same time, the model team has always adhered to the reliability of the arrow in the design and development process and enhanced the safety of ground equipment. Zhang Tao, the overall deputy director of the overall design department of the First Hospital of Aerospace Science and Technology Group, introduced that there are three main technical states of the rocket, which further improves reliability.
