Source: Xinhua | 2019-11-08 14:46:46 | Editor: zh

BEIJING, Nov. 8 (Xinhua) -- China has successfully tracked and received data from the newly launched Earth observation satellite Gaofen-7, according to the Chinese Academy of Sciences (CAS).

The China Remote Sensing Satellite Ground Station has received 616.6 GB of data with the highest transmission rate among civil Earth observation satellite data reception, according to the Aerospace Information Research Institute under the CAS.

The Gaofen-7 satellite has adopted variable coding and modulation technology, effectively improving its downlink transmission efficiency of satellite data. The China Remote Sensing Satellite Ground Station also developed new ground data receiving devices for adaptive, fully automatic and reliable reception of multiple satellite data.

Launched on Nov. 3, Gaofen-7 is China's first civil-use optical transmission three-dimensional surveying and mapping satellite that reaches the sub-meter level. It is expected play an important role in land surveying and mapping, urban and rural construction and statistical investigation.

French startup ThrustMe found fast route to orbit through China's Spacety
by Andrew Jones — November 25, 2019

French propulsion startup ThrustMe unexpectedly made it into orbit early this month with its innovative propulsion system placed aboard a Chinese cubesat.

Dianfeng, or Xiaoxiang-1 (08), a six-unit cubesat developed by privately owned Spacety, was a secondary payload on the launch of the Gaofen-7 civilian Earth observation satellite Nov. 2, along with a first satellite for Sudan.

As with many Chinese launches, secondary payloads were not announced until after launch success was declared, but further surprises were aboard.

Along with small laser communications payloads for Chinese commercial companies, Dianfeng carries ThrustMe's I2T5 non-pressurized, cold gas thruster fueled by solid iodine, which the company says is a first of its kind.

Designed for three- to six-unit cubesats, the 0.9-kilogram wet mass, low-thrust system allows a level of propulsion for collision avoidance, expanding time in orbit or assisting deorbiting as part of debris mitigation.

Founded in 2017, ThrustMe sought to commercialize iodine-based propulsion technology. It quickly developed a cold gas thruster and is working on an electric propulsion system for smallsats.

With an international team with expertise in fields such as space engineering, plasma physics, materials science, fluid dynamics, electronics and chemistry, ThrustMe has overcome challenges of dealing with corrosive iodine for space-based propulsion. The products can be shipped pre-filled and remain non-pressurized during launch.

The cooperation between the ThrustMe and Spacety developed rapidly, with a deal inked in February this year resulting in the early November launch.

"The speed and process of decision-making was quick and clear," Ane Aanesland, joint founder and CEO of ThrustMe, told SpaceNews. "The execution of the project was very efficient."

Aanesland said ThrustMe had received lots of interest from potential clients, but Spacety was willing to take the risk of employing an untested propulsion system.

Spacety, founded in 2016 and based in Changsha in central China, describes itself as specializing in low-cost, high-performance and reliable microsatellite platforms. The launch was the ninth the company has been involved in, with Dianfeng being the company's 15th satellite in orbit.

It is working with partners including LaserFleet, a spinoff from the Chinese Academy of Sciences (CAS) that plans to build a low Earth orbit constellation providing broadband services through laser communications. Spacety quickly recognized the opportunities presented by ThrustMe.

Weijia Ren, co-founder and CTO of Spacety, said in a post-launch news release that the firm, "saw the potential for us in a long-term collaboration with ThrustMe so we can provide the best propulsion solutions to our clients in China."

Notably, ThrustMe needed — and received — assistance from the French government and embassy to get the deal through fast. However, while cooperation developed quickly, there will be a wait before the parties can assess the performance of the system and chart deeper cooperation.

The first month of the mission will be dedicated to commissioning. After this, four other payloads, including two laser communications technology demonstrations and a multispectral imager, will be tested before the I2T5 thruster. This means it will be between two-to-six months before the results come in.

Spacety said it was unable to comment before testing of the propulsion system. But Aanesland says both companies have expressed keen interest in furthering cooperation. And while talks with other Chinese firms have taken place, Spacety stood out.

Tianyi Lan, founder of Ultimate Blue Nebula Co., Ltd.,a Beijing-based space consulting company, told SpaceNews that more such deals between European and Chinese firms can be expected.

"Compared with U.S. export policies and regulations, [the] European space environment is better ... The [biggest] barrier should be the ITAR-like regulations, but more and more European companies are developing ITAR-free components or devices to meet the regulations," Lan says.

Lan notes that Surrey Satellite Technology Ltd, GomSpace, ISIS and Thales Alenia Space have all previously developed good partnerships with Chinese space companies.

He also underlines that the space industry is very much international, with "everyone looking for more business benefits from the international market."

"We believe that new companies like ThrustMe will gain more market in China, and China's new space companies will create new cooperation opportunities with EU companies, based on flexible launch rates and price, manufacturing costs, and a huge market," Lan said.

Aanesland says China has not yet truly fostered a culture of innovation, presenting opportunities for European companies and win-win cooperation, but that window may soon close.

"I find it extremely fascinating what is happening in China. If you look at R&D development and how quickly they work, if we don't start working with China now, we'll be left on the sidelines."

ThrustMe will see a demo of its NPT30 miniaturized electric propulsion system on the GomSpace GOMX-5 ESA mission, to launch in 2021. Spacety's next mission could come as soon as late November, and is also developing larger satellite platforms.

BEIJING, Aug. 20 (Xinhua) -- The China National Space Administration announced on Thursday that the Gaofen-7 Earth observation satellite has been put into service, representing significant progress for the country's surveying and mapping capabilities.

Launched on Nov. 3, 2019, Gaofen-7 is China's first civil-use optical transmission 3D surveying and mapping satellite that reaches the sub-meter level.

Equipped with two line-scan cameras and a laser altimeter, the satellite can provide 1:10,000 scale satellite 3D mapping for users in China and countries participating in the Belt and Road Initiative.

During in-orbit tests, satellite functions such as the monitoring of geographical conditions, agricultural surveys, and road constructions have been verified, said Zhang Kejian, head of the administration.

In May, using data from the Gaofen-7 and Ziyuan III satellites, scientists drew a 1:10,000 scale topographic map for surveyors to measure the height of Mount Qomolangma.

Since the Gaofen project began in 2010, China has had an increasingly clearer view of the planet. According to the administration, data from the Gaofen series of satellites have been used in more than 20 industries across the country.

Images captured by the Gaofen-2 satellite were used to help monitor the construction work of two makeshift hospitals, Huoshenshan and Leishenshan, in Wuhan, after the COVID-19 outbreak.

Gaofen-3 has contributed to the monitoring of the flood situation along Poyang Lake, China's largest freshwater lake, in the eastern province of Jiangxi.

With Gaofen satellite data, researchers also conducted ecological environment investigations for poor areas in the northwestern province of Gansu.

"Gaofen-7 will further meet the needs of users in basic mapping, global geographic information, monitoring, and evaluation in urban and rural construction, etc.," said Zhang.

Китай ввел в эксплуатацию спутник "Гаофэнь-7"
2020-08-20 19:10:10丨Russian.News.Cn

Пекин, 20 августа /Синьхуа/ -- Спутник наблюдения Земли "Гаофэнь-7" в четверг был официально введен в эксплуатацию, что свидетельствует о значительном прогрессе страны в области геодезической съемки и картографирования, объявило Государственное космическое управление /ГКУ/ Китая.

"Гаофэнь-7", запущенный 3 ноября 2019 года, является первым в Китае спутником гражданского назначения для стереоскопической съемки и картографирования, который выполняет съемку с пространственным разрешением менее одного метра. Он может обеспечить картографирование в 3D-формате с масштабной шкалой 1:10000 для пользователей в Китае и странах, расположенных вдоль "Пояса и пути".

В ходе орбитальных испытаний были проверены такие функции спутника, как мониторинг географических условий, измерение посевной площади сельскохозяйственных культур, и мониторинг автодорожного строительства, сообщил глава ГКУ Чжан Кэцзянь.

В мае с.г. с помощью данных, переданных со спутников "Гаофэнь-7" и "Цзыюань-3", ученые составили карту масштабом 1:10000 для геодезистов, чтобы измерить высоту горы Джомолунгма.

С момента начала реализации проекта "Гаофэнь" в 2010 году данные со спутников этой серии космических аппаратов уже использовались в более чем 20 отраслях промышленности по всей стране.
