Four days after the launch of Tianhui-1B mapping satellite, China has launched a new optical remote sensing satellite on May 10, 2012 from the Taiyuan Satellite Launch Center. Launch of Yaogan Weixing-14 (YG-14) satellite took place at 07:06UTC using a Long March 4B (Chang Zheng-4B) launch vehicle from the LC9 launch complex.

Once again, the official Chinese media refer the new satellite as a new remote sensing bird that will be used for scientific experiments, land survey, crop yield assessment, and disaster monitoring. As was the case in the previous launches of the Yaogan Weixing series, western analysts believe this class of satellites is being used for military purposes.

Some believe that YG-14 is a new class of optical observation satellite containing sensors developed by CAST’s 508 institute and the Changchun Institute of Optics.

Together with Yangan Weixing-14 there was another passenger on board, the small 9.3 kg TT-1 (Tiantuo 1) that was built by the National University of Defense Technology. This project started in 2009 and is the first Chinese nano-satellite that integrates the functions of satellite control, power distribution, data transfer and attitude control onto a single integrated electronic board.

Tiantuo-1 will perform experiments on optical imaging, detection of on-orbit atomic oxygen intensity and receiving signals from the marine Automatic Identification System (AIS).
Its dimensions are 425 mm x 410 mm x 80 mm.

This was the 162nd successful Chinese orbital launch, the 162nd launch of a Chang Zheng launch vehicle, the 38th successful orbital launch from Taiyuan and the second from Taiyuan this year, becoming the seventh successful orbital Chinese launch in 2012.

Looking back to the Yaogan Weixing launch series:

The first Yaogan Weixing satellite (29092 2006-015A) was launched by a Chang Zheng-4C (Y1) from the Taiyuan Satellite Launch Center on April 27, 2006. Developed by Shanghai Academy of Spaceflight Technology (SAST), the details about this satellite were closely guarded, but later it was said that this was the first Jianbing-5 satellite, equipped with the first space-based synthetic aperture radar (SAR).

The second satellite on the series, the Yaogan Weixing-2 (31490 2007-019A), was launched on 25 May, 2007, by a Chang Zheng-2D (Y8) from the Jiuquan Satellite Launch Center. Details were also restricted, though it is claimed that this spacecraft is an electro-optical military observation satellite also known as JB-6 Jianbing-6, complementing the results of the Yaogan Weixing-1. This satellite was developed by the China Academy of Space Technology (CAST).

Another SAR mission was launched on November 11, 2007 when the Yaogan Weixing-3 (32289 2007-055A) satellite was orbited by a Chang Zheng-4C (Y3) launch vehicle from Taiyuan.

Yaogan Weixing-4 (33446 2008-061A) was launched on December 1, 2008. This was the second electro-optical satellite on the series and was launched by a Chang Zheng-2D (Y9) from Jiuquan. Other satellite on the Jianbing-6 series were Yaogan Wexing-7 (36110 2009-069A), launched on December 9, 2009 from Jiuquan by a Chang Zheng-2D (Y10), and Yaogan Weixing-11 (37165 2010-047A) launched on September 22, 2010, by the Chang Zheng-2D (Y11) launch vehicle from Jiuquan.

The first second-generation electro-optical reconnaissance satellite developed by CAST, Yaogan Weixing-5 (33456 2008-064A), was launched on December 15, 2008. The launch took place from Taiyuan by the Chang Zheng-4B (Y20) rocket. Yaogan Weixing-12 (37875 2011-066B) was other second-generation electro-optical reconnaissance satellite, being launched on November 11th, 2011, by the Chang Zheng-4B (Y21) launch vehicle from Taiyuan.

Yaogan Weixing-6 (34839 2009-021A), launched by a Chang Zheng-2C-III (Y19) from Taiyuan on April 22, 2009, was a second-generation SAR satellite developed by SAST, having a spatial resolution of 1.5m.

Other second-generation SAR satellites were the Yaogan Weixing-8 (36121 2009-072A), launched on December 15, 2009, by the CZ-4C (Y4) also from Taiyuan, the Yaogan Weixing-10 (36834 2010-038A) launch on August 9, 2010, by the Chang Zheng-4C (Y6) launch vehicle from Taiyuan; and the Yaogan Weixing-13 (37941 2011-072A) launch on November 29, 2011, by the Chang Zheng-2C (Y20) launch vehicle from Taiyuan

The YaoGan Weixing-9 mission, launched March, 2010 from Jiuquan, had a different architecture from the previous missions on the series. Launched by Chang Zheng-4C (Y5) rocket, the mission placed a triplet of satellites in Earth orbit. Flying in formation these three satellites appeared to be like a type of NOSS system.

China will launch another three satellites for the Beidou system.

Meanwhile, the system is expected to be adopted by some of China's neighboring countries in the next year or two,
an official said.

"The trial service of the Beidou system shows it can provide a high-quality regional service," said Ran Chengqi, director of the China Satellite Navigation Office, at the third China Satellite Navigation Conference, which opened in Guangzhou, capital of Guangdong province, on Wednesday.

"Many of China's neighboring countries, such as Pakistan and Mongolia, have shown strong interest in the system," Ran said."Technical discussions are under way, and hopefully Beidou products can enter these markets in one to two years."


Academic discussions and exhibitions showing Beidou's latest navigational and industrial applications will be held during the conference, which runs from Wednesday to Saturday. Around 1,500 experts and officials from countries including the United States, Russia and Japan are expected to attend the meeting.

Beidou currently has 11 satellites, and the positioning precision has reached 10 meters in most parts of the Chinese mainland. Its performance will improve after three more satellites are launched into space this year, Ran said.

Two satellites will be launched together on a single rocket in August, and another will be launched in October, Ran said.

"China will formally announce plans to provide free positioning, navigation and time services for customers in the whole Asia-Pacific region by the end of the year," Ran said.

China will continue to improve the performance of Beidou, and by 2014, it will expand its service area, aiming for global coverage, Ran said.

"Some countries, including Indonesia and Australia, have cooperated with China for the research and application of the system," said Liu Jingnan, a member of the Chinese Academy of Engineering, who specializes in satellite surveying and mapping.

For example, some countries, such as Australia, New Zealand, Singapore and some European countries, have cooperated with Chinese research institutes, including Wuhan University, to set up stations in these countries to trace Beidou satellite signals for future application of the system, such as in fisheries and agriculture, said Liu.

"Such stations can greatly enhance the preciseness of satellite positioning to as high as just a few centimeters, which is important for the application of this system in industrial use," Liu said.

Currently, products based on the Beidou system, such as car and ship navigators, have been used in China, but the number is still very small compared to GPS users, said Cao Chong, director of the Advisory Center of the China Association for Global Navigation Satellite Systems.

"Beidou was put into service just a few years ago, so it is hard for it to compete with GPS," Cao said. "I think products that are compatible with both Beidou and other global positioning system technologies, such as that of GPS, will flourish in the next few years in China, and hold a majority share of the market."

David Turner, deputy director of the Office of Space and Advanced Technology within the US State Department, echoed Cao's opinion.
"It is better to encourage cooperation for compatibility," he said. "For example, if a navigator is compatible with Beidou and GPS and Russia's GLONASS, it will be much more precise."
