Chinese satellites begin UN environment, natural disaster service

www.chinaview.cn 2009-03-31 00:19:51

 BEIJING, March 30 (Xinhua) -- Two environment and disaster monitoring satellites officially began operating Monday, China's State Administration of Science Technology and Industry for National Defence (SASTIND) said.

 The two small optical land observation satellites, Huanjing-1A and Huanjing-1B, would play an important role in providing data as part of the United Nations Platform for Space-based Information for Disaster Management and Emergency Response (UN-SPIDER), a UN program to provide such information universally, an unnamed SASTIND official told Xinhua.

 With advanced optical, thermal infrared and hyper-spectral remote sensing equipment, the satellites would greatly raise China's ability to monitor the environment, Wu Xiaoqing, Vice Minister of Environmental Protection, said at a ceremony to mark the event.

 During their trial services since late 2008, the satellites provided images for members of Asia-Pacific Space Cooperation and helped with management of the Australian bushfires, which claimed 210 lives in February.

 The two optical satellites, the first of their kind put into space by China, were launched from the Taiyuan Satellite Launch Center in Shanxi Province on a Long March 2C rocket on Sept. 6, 2008.

 They can provide a global scan every two days in a lifespan expected to last more than three years.

 The satellites form part of China's effort to create a constellation of four optical and four radar satellites for environmental and natural disaster monitoring.

 Radar satellite Huanjing-1C, the third in the constellation, is expected to be launched this year.

 Small, or miniaturized, satellites are characterized by small size and low weight, usually under 1,000 kg. They require smaller, cheaper launch vehicles and can sometimes be launched in multiples.

Chinese Satellites Begin Disaster Monitoring

Wednesday 08 Apr 2009

China's first two satellites dedicated to environment and disaster monitoring began official operations on 30 March, according to Chinese state media.

The satellites, Huanjing-1A and Huanjing-1B (huanjing means 'environment' in Chinese), will be used by the Ministry of Civil Affairs, in charge of disaster relief and reduction, and the Ministry of Environmental Protection.

They will also provide data to the UN Platform for Space-based Information for Disaster Management and Emergency Response (UN-SPIDER) via the soon-to-be opened Beijing office, Chen Qiufa from the State Administration of Science Technology and Industry for National Defence told Xinhua News Agency.

Both satellites are equipped with advanced optical, thermal infrared and hyper-spectral remote sensing equipment. They each carry two charge coupled device cameras with 30 metre resolution and 720 km width. Huanjing-1A also carries imaging multi-spectral (visible/infrared) radiometers with a spatial resolution 100 metres. Huanjing-1B carries an infrared camera with a maximum resolution of about 150 metres. They can jointly image China's entire territory in two days.

Since beginning trial services late last year, the satellites have provided images for members of Asia-Pacific Space Co-operation and the Australian government during the bushfires disasters that struck the country's southeast in February.

The satellites were launched on 6 September 2008 from the Taiyuan Satellite Launch Center in Shanxi province. They were placed into sun-synchronous orbits in the same orbital plane of 97.95 degrees at 650 km altitude. They passed in-orbit testing in February.

Huanjing-1A and Huanjing-1B are the first in a planned constellation of four optical and four radar satellites dedicated to environmental and disaster monitoring. All the satellites will be capable of visible, infrared, multi-spectral and synthetic aperture radar imaging. Eventually, the constellation will be able to capture a complete image of China every 12 hours.

Chinese officials expect to launch the radar satellite Huanjing-1C this year. Huanjing-1C will carry an S-band synthetic aperture radar for continuous, all-weather imaging. The SAR instrument will have a swath width of 100 km and be capable of 20 metre resolution imagery. The satellite will be placed in a 500 km, 97.3 degree, sun-synchronous orbit.

Huanjing series (China), Spacecraft - Earth observation

Current Status
China's first two Huanjing disaster monitoring spacecraft were launched on 6 September 2008.

Background
China is planning to launch 11 satellites over a period of 6 years under the Huanjing (Environment) programme. They will provide visible, infrared, multi-spectral, and synthetic aperture radar imaging for environment and disaster monitoring. The first phase calls for three satellites, two of which are equipped for visible, infrared, and multi-spectral imaging. A third spacecraft will carry a S-band synthetic aperture radar (SAR) for continuous, all-weather imaging. Phase two will comprise 8 satellites, four imaging and four SAR, in orbit simultaneously. The first two satellites, Huanjing-1A and 1B were launched by Long March 2C from Taiyuan on 6 September 2008. They were placed into sun-synchronous orbits in the same orbital plane of 97.95° at 650 km altitude, enabling them to covering all Chinese territory every 48 hours. Both satellites carry two CCD cameras with a resolution of 30 m. HJ-1A also carries imaging multi-spectral (visible/infrared) radiometers with a spatial resolution 100 m. This is replaced on HJ-1B by an infrared camera with a maximum resolution of about 150 m. The first two satellites have a design life of three years, but the Chinese plan to replace them when necessary. The ground control centre is in Xian. Huanjing-1C is a CAST 968-based SAR satellite fitted with a large radar antenna. Launch is scheduled for May 2009 into a 500 km, 97.3°, sun-synchronous orbit. The SAR instrument will have a swath width of 100 km and be capable of 20 m resolution imagery with an accuracy of 3 dB.

Может, наши ждут, как китайский цельнотянутый "Кондор" полетит, чтоб на их ошибках поучиться ?  
Или китайцы ждут наших?

Launch is scheduled in about 13 hours! (confirmed via two different sources including here: http://www.9ifly.cn/forum.php?mod=redirect&goto=findpost&ptid=61&pid=228889)

Т.е. пуск возможен завтра около 02:00 ЛМВ.

[Прол]

А антенну то, похоже, ОКБ МЭИ делало! Научат на свою голову.

[Liss]

Коллективный разум коллег на http://forum.nasaspaceflight.com/index.php?topic=30016.15 и http://www.9ifly.cn/thread-61-10-1.html указывает, что пуск состоится завтра утром около 06:00 по пекинскому, т.е. около 02:00 летнего московского. Носитель CZ-2C №Y17 будет нести в общей сложности четыре КА:
* Радиолокационный КА "Хуаньцзин-1C" (Huanjing-1C);
* Экспериментальный КА "Синьянь-1" (Xinyan-1) для отработки новых технических решений;
* Пара экспериментальных КА "Фэнняо-1" (Fengniao-1), которые разделятся уже в самостоятельном полете.

Launch time (assuming launch at 2200UTC). Launching from Taiyuan I suppose this will take longer than usual to confirm, so stay tunned...

Galactic Penguin SST пишет:

Too early I'm afraid: the blogs entry should actually read "the launch at six-something hours"! The Sun is still roughly an hour away from rising, and if the launch was that early the satellites would face darkness for the next half an orbit! Look for launch indications between 22:45 and 23:00 UTC.  [Шутливо]

[Lesobaza]

Should be at T-15 minutes by now.... the only reference I can see about this launch is that one of the buses taking the spectators to the viewing site has broken down.....
