Китайский спутник должен помочь нашему соотечественнику стать д.т.н.
ЦитироватьКитайский спутник FY-1D был запущен без калибровок ИК-датчиков и нестабильными калибровками видимых каналов. Построены технологии первичной и тематической обработки данных спутника, позволившие создать метод расчета карт температуры поверхности океана, соответствующей современным требованиями точности.

Технология обработки данных спутника FY-1D передана в NOAA/NESDIS (США) по их запросу.

ЦитироватьSeabed mapping pace speeds up

BEIJING, Sept. 14 (Xinhuanet) – China will accelerate its pace of mapping the deep seabed, Zhang Jixian, president of the Chinese Academy of Surveying and Mapping, told China Daily in an exclusive interview.

"In the near future, China's surveying and mapping science will gradually extend from the ground area to the country's 3 million square kilometers of water territory," Zhang said.

Unlike the electronic navigation chart released by the Chinese navy on Aug 25 with information mainly focusing on navigation, the future ocean map will concentrate on the geological features of the sea floors and the water depth, and the location of reefs.

In the land surveying and mapping industry, China has become one of the world leaders with the recent completion of its nationwide 1:50,000 map, but in offshore area mapping, "much needs to be done".

A nautical chart represents a maritime area and its adjacent coastal regions with information such as depths of water, heights of land, natural features of the seabed, details of the coastlines, navigational hazards, information on tides and currents and man-made structures like harbors, bridges and buildings.

Zhang said the surveying and mapping of reefs within China's water territory is under way, but the seabed surveying and mapping has a long way to go because the technology is not mature.

"The offshore surveying and mapping is totally different from that for the land, because water is flowing all the time that makes setting a fixed target so hard," he added.

At least the first step in mapping the water area has been taken with the recent unveiled maritime navigation chart.

"Surveying and mapping the marine areas will help people know the undersea resources and the ocean better," said Li Jingwei, general manager of Star Geomatics Park Investment Co Ltd.

As the marine economy was first mentioned in the 12th Five-Year Plan (2011-2015), many experts see a booming future for China's offshore development and exploration.

By the end of 2020, it is estimated the gross product of the country's marine industries, including offshore oil and gas exploration, marine transport, coastal tourism, fisheries and shipbuilding industry, will surpass 5.3 trillion yuan ($814 billion), according to China's Ocean Development Report in 2011.

Gao Zhiguo, director of the China Institute for Marine Affairs under the State Oceanic Administration, said the ocean is the next economic growth engine for China and so should be given thorough study.

China's pace in exploring the deep sea has been accelerating in recent years with the successful 5,188-meter dive of China's manned deep-diving submarine Jiaolong this year, and becoming one of the first two countries approved by the International Seabed Authority to look for polymetallic sulphide deposits in the Southwest Indian Ridge.

In December, China's first cartographic satellite will be launched, Zhang said, which will play an active role in China's future surveying and mapping industry.

The satellite will carry panchromatic cameras with 2.5 meter and 5 meter spatial resolution, and after it is fully operational, satellite images will be sent back every year covering the entire country.

Ровно четверть века назад, 27 июля 1987 г., репортеры Aviation Week & Space Technology с изумлением поведали миру, что китайские спутники семейства FSW имеют теплозащиту из толстого слоя дуба.

Насколько вы удовлетворены резонансом, который «Радиоастрон» получил среди ­научной общественности и в прессе?

Мы чувствуем очень большой интерес всего международного научного сообщества. ­Например, Китай настолько заинтересовался этим проектом, что планирует постройку своего аналога. В прессе сейчас внимания меньше, чем было при запуске телескопа, но это понятно: пока нет публикаций об ­открытиях.

А есть у кого предположение о названии и сроке запуска?

China Plans 2013 Release for 2 New Telecom Satellite Options
ЦитироватьNAPLES, Italy — The Chinese Academy of Space Technology plans to introduce its two new versions of China's DFH-4 telecommunications satellite platform starting next year, both featuring lithium-ion batteries and the option of ion-electric propulsion, an academy official said Oct. 4.

Both versions are intended to strengthen China's position in the global market for telecommunications platforms.

In a presentation here to the 63rd International Astronautical Congress, Yongxuan Xiao said that "with great support from [China's] native satellite operator," the first small-class version of DFH-4, called the 4S, will make its qualification flight as part of a commercial mission operated by China Satellite Communications Co. Ltd.

The DFH-4S is designed to be small enough to fit onto a Chinese Long March 3C rocket, which is less expensive than the Long March 3B vehicle that currently orbits China's telecommunications satellites.

At 3.2 meters tall and with a maximum launch weight of 3,800 kilograms, the DHF-4S is smaller than the standard-version DFH-4 now being flown, and considerably smaller than the DFH-4E, which is also scheduled to be ready for flight in the next two years.

DFH-4E will weigh up to 6,000 kilograms at launch and deliver between 9 and 11 kilowatts of power to its payload. Xiao said qualification tests of the satellite's principal subsystems will be completed in late 2012, and that it will be ready for sale to the market in 2013.

DFH-4 was introduced in 2006. After solar-array drive mechanism issues sharply reduced the life and functionality of two early versions, seven most recently launched models have worked well, with Venezuela's Venesat-1 having accumulated more than three years of in-orbit service life.

Xiao said the ion-electric thrusters, which at the customer's option may be used to replace conventional propellant to assure the satellite's in-orbit stability, have accumulated more than 3,700 hours of lifetime tests. Electric propulsion offers substantial weight savings over conventional propulsion, which can be used to purchase a less-expensive rocket or to add more payload capacity.

Xiao said that for the moment, the electric propulsion designs for DFH-4S and the larger DFH-4E call for electric propulsion to be used only for station-keeping, and not in "full electric" mode to power the satellite from its transfer orbit after separation from its launch vehicle to final geostationary position.

Up to now, China has sold telecommunications satellites mainly as part of package deals that include a launch aboard a Chinese Long March rocket and insurance coverage. Xiao said the Chinese Academy of Space Technology's goal is to break into export markets for the satellites themselves, with or without a Chinese rocket.
