China launches ninth orbiter for indigenous global navigation system

China launches ninth orbiter for indigenous global navigation system
English.news.cn 2011-07-27 07:58:03 FeedbackPrintRSS
XICHANG, Sichuan, July 27 (Xinhua)-- China successfully launched an orbiter into space at 5:44 a.m. Beijing Time Wednesday, as a part of its indigenous satellite navigation and positioning network known as Beidou, or Compass system, sources with the launch center said.

The orbiter,launched from the Xichang Satellite Launch Center in southwestern Sichuan Province, was boosted by a Long March-3A carrier rocket into a geostationary orbit.

China started to build up its own satellite navigation system to break its dependence on the U.S. Global Positioning System (GPS) in 2000.

Between October 2000 and May 2003, the country set up a regional satellite navigation system after launching three Beidou geostationary satellites.

The system was known as Beidou-1 and is said to have played an important role in the rescue efforts following the devastating earthquake in May 2008 in Wenchuan as it provided the only channel connecting the quake-hit area and the outside.

The Beidou-1 system can not meet growing demand, so a better functional Beidou-2 regional and global navigation system will be set up, Qi Faren, former chief designer for Shenzhou spaceships said in an interview with Xinhua early this year.

From April 2007 to April this year, China launched another eight orbiters to form its Beidou-2 system, which will eventually consist of 35 satellites.

The network will provide satellite navigation, time and short message services for Asia-Pacific regions by 2012 and global services by 2020.

Looks like the project is progressing well.

Galileo is fallen.

Galileo is fallen.

what does that mean?

 

[twocents]

what does that mean?

Galileo's planned frequency is very similar to that of China' Beidou. Since international space treaties stipulate a "first come, first serve" principle, Galileo will have to redesign its system for a different frequency. This is what I think he meant.

JIUQUAN, Gansu, July 29 (Xinhua) -- China launched an experimental orbiter into space from the Jiuquan Satellite Launch Center in northwest China's Gansu Province on Friday.

The SJ-11-02 orbiter was sent into space at 3:42 p.m. by a Long March II-C carrier rocket, according to the launch center. The orbiter belongs to the country's Shijian satellite family.

The orbiter, developed by China Space Co., Ltd. under the China Aerospace Science and Technology Corporation, will be used to conduct scientific experiments in space, the company said.

The launch marked the 142nd flight for the Long March rocket family

&#20013;&#24191;&#32593; Beijing on August 16, according to Voice of China <<CNR News>> reported today, 6:57, China Taiyuan Satellite Launch Center in the 'Long March-4B' carrier rocket, the success of 'Ocean two 'satellite into space. we connect the details of the Voice of China correspondent Li Xin.

Moderator: 'Ocean II' with the advanced satellite technology? What is the significance of its launch?

Reporter: 'Ocean II' ZHANG Qing-jun, said the chief architect of the satellite, the development of 'Ocean II' a number of key breakthroughs in satellite technology, which for the first time precise orbit determination, orbit determination accuracy of a centimeter, but also the first times to carry out laser satellite communication link test. 'Ocean II' should be said that China's marine motivation to fill the gaps in environmental monitoring satellites, monitoring studies of El Nino, global climate change research and so has very important significance.

'Ocean II' satellites is very much the key techniques, such as large static and dynamic balancing of rotating parts monitoring and control technology, there is a large high-precision attitude interference technology, and breakthroughs in the microwave remote sensing electromagnetic compatibility analysis of control system design and verification technology(http://*ww.f-paper.com/). Another very high localization rate of the satellite, the satellite control system platform products as local production more than 99%.

Satellite laser communication links will be the first satellite to carry out experiments, laser communications as a new means of communication with high-speed, high security and low distortion characteristics.

The STSS for China.
Another one will be launched tomorrow

that is 2 satellites in 2 days.

 

[J-20]

China space station prototype Tiangong 1 launch is suspended, due to the previous launch failed of experimental SJ-11-04... oh no...

Tiangong 1 was supose to be launch at 31th this month, 2 months later Shenzhou 8 to be launch, then have China the first construction on orbit.

Funny? They want to take guangdong? Do they know just the guangdong province had larger GDP and population than Vietnam?

I don't troll you bro, that what I have heard from the Vietnamese, remember I am 1/3 Vietnamese background, I had been living near the border between Cambodia and Vietnam so I know them more than you can imagine!!!

Hainan? Oh may be you don't know what Viet talking about you, they already claim the whole southeast China province such as Guangdong or Hainan was belong to the ancient great Viet, thus there are some extreme Viets appeal to take these lands back from your Chinese. Be aware!!! :

But anyway, just like you, sometime I feel that the Viets are so insane and scary, they think they are invincible in any fields, they are the best and others are inferiors!!!

Funny? They want to take guangdong? Do they know just the guangdong province had larger GDP and population than Vietnam?

With the Guangdong military region and the South Sea Fleet, it has much more firepower than the entire Southeast Asian nations combined, and a small nation can always talk about a big dream.

China's Moon orbiter Chang'e-2 travels 1.5 km into outer space

30 Aug, 2011, 03.17PM IST, PTI

BEIJING: China's second Moon orbiter Chang'e-2, on a drift in outer space after completing its lunar mission, has travelled 1.5 million km away from Earth and is orbiting second Lagrange Point (L2), where gravity from the Sun and Earth balances orbital motion of a satellite.

Chang'e-2 entered L2's orbit last Thursday after spending 77 days travelling away from its previous orbital path around the Moon, the State Administration of Science, Technology and Industry for National Defence (SASTIND) said today.

The SASTIND said that China is now the world's third country or organisation to successfully put a spacecraft into orbit around L2, after the European Space Agency ( ESA) and the National Aeronautics and Space Administration ( NASA) of US.

The Chang'e-2 will carry out exploration activities around L2 in the coming year, SASTIND said, according to official Xinhua news agency.

There are five "Lagrange Points" about 1.5 million km away from the Earth in the exact opposite direction from the Sun.

Putting a spacecraft at any of these points allows it to stay in a fixed position relative to the Earth and Sun with a minimal amount of energy needed for course correction.

The orbiter completed all of its assigned tasks after blasting off on October 1 last year, according to the SASTIND.

Although the orbiter was only supposed to remain in space for six months, the SASTIND decided to assign additional tasks to it, as it still had fuel in its reserve tanks.

Travelling into outer space from the Moon's orbit was one of the orbiter's most important missions, SASTIND said.

Before arriving at its current position in outer space, the Chang'e-2 took photos of the northern and southern poles of the moon. It then descended to a lower orbit, approximately 15 km away from the moon's surface, where it captured high-resolution images of the Sinus Iridum, or "Bay of Rainbows," an area where future moon probes may land.

The SASTIND is reportedly planning to launch measure and control stations into outer space by the end of the second half of next year. The Chang'e-2 will be used to test the two stations' functionality at that time.

China's ambitious three-stage moon mission will include a moon landing, as well as the launch of a moon rover during the second stage, which is scheduled to take place in 2012.

During the third phase, another rover will land on the moon and return to Earth with lunar soil and stone samples for scientific research around 2017.

China does not currently have a timetable in place for a manned moon landing. It launched its first lunar probe, the Chang'e-1, in October 2007.

In 2003, China became the third country after Russia and US to send a human into space. Two more manned space missions followed, the most recent of which took place in 2008.
