China launched the first of its new-generation data relay satellites on Sunday night as part of the preparatory work for the nation's next manned space missions.

The Tianlian II-01 was lifted off at 11:51 pm atop a Long March 3B carrier rocket at the Xichang Satellite Launch Center in Sichuan province and later was placed on a geostationary transfer orbit, according to a statement from the China Academy of Space Technology that developed and built the satellite.

The spacecraft is the first in China's second generation of data relay satellite, the academy said, adding its entry into service will substantially improve the country's space-based data relay capability.

Next, researchers will start designing the Tianlian II-02 and Tianlian II-03 that will join the Tianlian II-01 to form a network, according to the statement.

With a DFH-4 framework, Tianlian II-01 is mainly tasked with relaying data for the country's piloted spaceships, space labs, low- and mid-orbiting satellites as well as its future space station. It will also be used to track and monitor these spacecraft.

China's first-generation data relay satellite network, the Tianlian I system, now has four satellites. The first of them was launched at the Xichang center in April 2008. They have serviced several important space activities such as the rendezvous and dockings between the Tiangong I space lab and Shenzhou spaceships.

延伸阅读：长五遥三火箭预计7月中下旬复飞

1月29日，《中国航天科技活动蓝皮书（2018）》重磅发布，航天科技集团党组成员、副总经理杨保华接受媒体采访时透露，长征五号遥三火箭目前总体进展较好，计划在7月中下旬完成复飞。

”“The blue book on China's space science and technology activities (2018)“” was released on jan 29
Yang baohua, deputy general manager of the aerospace science and technology group , said in an interview with the media that the long March 5 rocket is making good progress and plans to launch in mid-to-late July.

今年，中国航天将再迎高密度发射，全年发射次数将超30次，发射航天器超50颗。那么，今年的宇航发射有哪些特点呢？

航天科技集团党组成员、副总经理 杨保华：一个是频次高，我们今年计划执行超过30次的宇航发射任务。二是场点多，我们去年主要集中在传统的三个发射场，酒泉、太原和西昌，今年我们还要有两次在文昌，还有一个海上发射。第三个特点就是任务重，今年年底要实现嫦娥五号的发射；今年7月份左右，我们长征五号遥三要恢复发射，分量非常重。

“胖五”的复飞任务，将发射基于东方红五号卫星公用平台研制的新技术试验卫星——实践20号。杨保华表示，2017年7月2日长征五号遥二火箭发射失利后，航天科技集团认真完成了技术归零，并在2018年全年开展了后续质量工作。目前总体进展较好，还有一些局部工作有待完成。遥三火箭计划在7月中下旬完成复飞，这个计划是可控的。
The "fat five" mission will launch the shijian-20, a new technology test satellite based on the public platform of the dongfanghong 5 satellite.Yang baohua said that after the failure of the long March 5 rocket launch on July 2, 2017, the aerospace science and technology group earnestly completed the technical zeroing and carried out follow-up quality work throughout 2018.At present, the overall progress is good, and some partial work still needs to be completed.The rocket is scheduled to launch in mid-to-late July. The plan is manageable.

嫦娥五号任务是中国探月三期工程的标志性任务，将实现我国首次月球采样返回。如果长征五号遥三火箭任务顺利完成，嫦娥五号任务将在年底由长征五号遥四火箭实施发射。
The chang 'e-5 mission, the signature of China's third lunar exploration phase, will carry out the country's first return of lunar samples.If the third long March 5 rocket mission is successfully completed, the chang 'e-5 mission will be launched by the long March 5 rocket by the end of the year.

At about 22:41 on April 20, 2019, China launched the Beidou 3 G2Q satellite at the No. 3 launch pad of the Xichang Satellite Launch Center with the Long March 3B-Y59 carrier rocket. This satellite belongs to the inclined geosynchronous orbit satellite. It is the "substitute" satellite of the Beidou 3 global network satellite. It is the 20th network satellite of the Beidou 3 system and the 44th of the Beidou satellite system. After entering its intended orbit and completing the on-orbit test, it will participate in the operational service of the Beidou No.3 system. 

China sends a new satellite of the BeiDou Navigation Satellite System (BDS) into space from the Xichang Satellite Launch Center in Xichang, southwest China's Sichuan Province, April 20, 2019. (Xinhua/Guo Wenbin)

XICHANG, April 20 (Xinhua) -- China sent a new satellite of the BeiDou Navigation Satellite System (BDS) into space from the Xichang Satellite Launch Center in Sichuan Province at 10:41 p.m. Saturday.

Launched on a Long March-3B carrier rocket, it is the 44th satellite of the BDS satellite family and the first BDS-3 satellite in inclined geosynchronous Earth orbit.

After in-orbit tests, the satellite will work with 18 other BDS-3 satellites in intermediate circular orbit and one in geosynchronous Earth orbit.

Yang Changfeng, chief designer of the BeiDou system, said that the hybrid constellation design, in which three groups of satellites at different orbital regimes work in concert, was an exclusive BDS innovation and the world's first.

It will increase the number of visible satellites in the Asian-Pacific Region, providing better service for the region, Yang said.

The launch was the 302nd flight mission for the Long March series of carrier rockets, and the 100th for the Long March-3B.

So far, a total of four BeiDou test satellites and 44 BDS satellites have been sent to preset orbits via 36 flight missions launched by Long March-3A and Long March-3B carrier rockets.

The launch on Saturday also marked the first launch of the BDS in 2019. This year, about 8-10 BDS satellites are scheduled to be launched, wrapping up launch missions of all BDS-3 satellites in medium Earth orbit.

China began to construct its navigation system, named after the Chinese term for the Big Dipper constellation, in the 1990s and started serving the Asia-Pacific Region in 2012.

According to Yang, the positioning accuracy of the system has reached 10 meters globally and five meters in the Asia-Pacific Region after the system started to provide global service at the end of last year.

The BDS-3 system is to be completed in 2020. China is also planning to finish building a high precision national comprehensive positioning, navigation, and timing (PNT) system on the basis of the BDS by 2035.

Yang noted that China is willing to share the achievements of the BDS with other countries.

The BDS has been widely used around the world, like building construction in Kuwait, precision agriculture in Myanmar, land survey and mapping in Uganda and warehousing and logistics in Thailand.

The BDS will serve the world and benefit all mankind with more powerful function and better performance, said Yang.

China's LinkSpace successfully launches reusable rocket to a new height

China's private rocket company LinkSpace successfully launched a reusable rocket in east China's Shandong Province on Friday. The RLV-T5 rocket flew to a height of 40 meters and then safely landed, in 30 seconds.

On March 27, the company finished its first low-altitude launch at a height of 20 meters.

Whenever the term "reusable rocket" is mentioned, people would at once link it to the U.S. giants like SpaceX and Blue Origin. Now, China's LinkSpace is hoping to make its presence felt in the market.

Founded in 2014, LinkSpace is engaged in the development of reusable rockets and liquid rocket engine technology. The RLV-T5 rocket was put into production in May 2018. The 8.1-meter high rocket has a take-off weight of 1.5 tons, and uses five liquid rocket engines in parallel to get off the ground.

Currently, LinkSpace's 20-member team has started the research and development of a sub-orbital reusable rocket named RLV-T6.

It is expected that the final assembly of the new rocket will be completed by the end of this year. The company's first small commercial rocket, NEWLINE-1, will target the microsatellite launch market and is scheduled to make its maiden flight around 2021.
