Source: Xinhua| 2019-08-16 16:14:18|Editor: Li Xia

BEIJING, Aug. 16 (Xinhua) -- Satellite remote sensing imagery with high resolution has been used in China's ongoing third national land survey, said officials Friday.

Surveyors have used satellite imagery with a resolution of one meter as base maps, which can distinguish objects that measure tens of square meters on the ground.

If county-level surveyors in field investigations find the land status is inconsistent with that on the satellite images, they will take photographs with location and azimuth information, for later verification by superior departments.

The main task of the survey, starting from October 2017, is to make a comprehensive record of China's land resources and utilization status, and to improve national land data, said Chen Chenzhao, deputy chief inspector of China's Ministry of Natural Resources, at a press conference held by the State Council Information Office.

The use of satellite remote sensing technology has improved the accuracy of the survey, which is expected to be completed by 2020, said Chen.

China's first national land survey ended in 1996 and the second was conducted between 2007 and 2009.

Source:Global Times Published: 2019/9/2 10:16:20

China and Russia will soon put in place an agreement involving their respective satellite navigation systems, with aims to promote the compatibility and interoperability of the BeiDou and GLONASS navigation systems.

The cooperation agreement has been confirmed by both sides during the sixth meeting of the committee of the Russia-China Project Committee on Important Strategic Cooperation in Satellite Navigation (RCPCISCSN) over the weekend. And it will take effect soon.

The meeting deliberates work reports from four work groups involving compatibility and interoperability, satellite based augmentation systems, the building of stations, supervision and assessment, as well as combined application. Major development on these areas has been achieved.

The two sides signed an inspection certificate regarding the location of measuring stations and approved a feasibility study report on agricultural projects.

China and Russia have agreed on the text of the cooperation agreement on the timing compatibility of BeiDou and GLONASS during the meeting. Multi-mode, multi-frequency radio frequency chips that support both BeiDou and GLONASS were also released during the meeting, with the two sides jointly analyzing the business prospects of more chip application and cooperation researches.

To follow up, China and Russia will stay in close communication on development plans and the project implementation of both systems. They will also actively explore new cooperative areas and projects to promote result sharing and cooperation for mutual benefit between BeiDou and GLONASS.

The meeting marked a major step in satellite navigation cooperation between China and Russia, which some industry insiders said has far-reaching implications for the US' GPS navigation system.

In 2015, China and Russia set up the committee of RCPCISCSN to establish a government-level mechanism and platform for deeper synergies between their respective navigation systems.

The BeiDou Navigation Satellite System (Xinhua)

At present, the BDS, independently constructed and operated by China, has officially provided RNSS (Radio Navigation Satellite System) services worldwide, with a total of 39 in-orbit satellites, after high-density launches of BeiDou-3 since 2017.

SHANGHAI, Sept. 5 (Xinhua) -- China's BeiDou Navigation Satellite System (BDS), a global geolocation network, currently has 39 in-orbit satellites and is expected to be completed in 2020, authorities said Wednesday.

At present, the BDS, independently constructed and operated by China, has officially provided RNSS (Radio Navigation Satellite System) services worldwide, with a total of 39 in-orbit satellites, after high-density launches of BeiDou-3 since 2017, said Yang Jun, deputy director of China's Satellite Navigation System Management Office, at a two-day conference on aerospace technology innovation in Shanghai, which concluded on Thursday.

China plans to send five to seven BDS satellites into space this year and two to four in 2020, which will help fully complete the BDS global network.

Yang said the BDS has always taken innovation and development as the driving forces for its construction, providing steadily improving positioning accuracy and new functions of global short message communication, international rescue and satellite-based augmentation service.

The navigation services based on the BDS are also changing people's lives, by being applied in e-commerce, manufacturing of mobile intelligent terminals and positioning services.

China is promoting its integration into global navigation services, with the BDS compatible with GPS and GLONASS, and by participating in various international organizations such as the International Civil Aviation Organization and the International Maritime Organization.

In the future, the BDS will also be further integrated with the Internet, the Internet of things, 5G and big data, according to Yang.

China began to construct the BDS, named after the Chinese term for the Big Dipper asterism, in the 1990s. The system started serving China with its BDS-1 satellites in 2000 and started serving the Asia-Pacific region with its BDS-2 satellites in 2012.

Polar observation satellite will debut soon
By ZHAO LEI | China Daily | Updated: 2019-09-09 09:16

​

Network will improve country's ability to monitor Arctic and Antarctic regions

China will soon launch the first satellite in its space-based polar observation network in an attempt to improve the nation's polar research capability, according to project insiders.

The BNU-1 will be lifted atop a Long March 4B carrier rocket from the Taiyuan Satellite Launch Center in Shanxi province before the end of this month, said Li Chun, BNU-1's project manager at Aerospace Dongfanghong Development in Shenzhen, Guangdong province. The company, which designed and built the spacecraft, is part of the China Academy of Space Technology in Beijing.

The small satellite weighs about 20 kilograms and will carry three experimental payloads - a multispectral camera; a high-resolution visible-light camera; and an automatic identification system receiver, a device for ship identification. It will work in a sun-synchronous orbit more than 730 kilometers above the Earth for up to two years.

Once put into service, it will be operated by the Joint Center for Polar Research of Chinese Universities and will mainly be tasked with observing the environmental changes of the Antarctic and Arctic, detecting and providing early warnings of ice shelf collapses and tracking the sources of smog - a hazardous atmospheric phenomenon haunting many countries, especially developing ones like China, Li said.

BNU-1 and other satellites in the network will enable China to put an end to its heavy reliance on Western companies' satellites for images and data from polar regions, he said.

Research and development of BNU-1 was initiated in February last year by researchers at Beijing Normal University's College of Global Change and Earth System Science, who called for space-based assets for their work.

Xu Guanhua, an academician of the Chinese Academy of Sciences and former minister of science and technology, was quoted in a statement previously published by Aerospace Dongfanghong Development as saying that the BNU-1 mission will be a milestone in China's polar research because it will extensively boost the country's investigations of polar regions and global environmental changes.

In the past, polar regions' data available to Chinese scientists were mainly acquired by Chinese ships and polar stations, but those means have long been restricted by tough natural conditions or the inaccessibility of many areas, experts said.

Zhang Di, the satellite's chief designer at Aerospace Dongfanghong Development, told Daily Sunshine, a Shenzhen newspaper, that the BNU-1 mission will also be useful to shipping companies as it will be capable of monitoring and reporting ice movement in sailing routes and autonomously preparing navigation routes for ships.

Orbiting the Earth 14 times a day, the satellite would support China's endeavors to develop Arctic sea lanes for the Chinese shipping industry, he said.

China North Industries Group announced on Friday their assisted BeiDou Navigation Satellite System (BDS), a satellite-based positioning system widely used with GPS-capable cellular phones, has served over 300 million users.

The assisted BDS, which the company said can achieve sub-meter location accuracy, has filled the gap between China and the U.S. in the area of satellite-based positioning technology in the mobile communication industry.

The self-developed sat-nav system was first applied in the military sector, and has been gradually adopted by civil industries including weather forecasting, natural disaster prevention and agriculture since 2012. Over the past two years, the BDS-based chips have been embedded in millions of mobile devices.

With the 5G technology now in commercial use, and the wide application of Internet of Things (IoT) devices, China's sat-nav industry value will reach 400 billion yuan by 2020, according to the GNSS (global navigation satellite system) and LBS (location-based service) Association of China (GLAC).

BDS will start to provide positioning and navigation services to its global users by 2020, said Yu Xiancheng, president of the GLAC, on Tuesday.

In the 5G era, the "5G+BDS" combo will be widely seen in scenarios that require fast data transmission speed, low network latency, and precise location and navigation services. such as autonomous driving, logistic systems, air traffic control, and robot patrolling.

According to GLAC data, the annual growth rate of the nation's satellite industry has remained at 20 percent since 2012, while the BDS has contributed about 80 percent. The system, along with related products and services, has generated 194.7 billion yuan so far.

Data shows over 80 million domestic BDS-based products had come into service by the end of 2018.
