What's new

China Space Military:Recon, Satcom, Navi, ASAT/BMD, Orbital Vehicle, SLV, etc.

Indians have no satellites of their own?

Anyway, I hope the people in the affected areas of India will tide over the difficulties as soon as possible.
India has satellite of their own. The picture on the left hand side half is from Resourcesat-2, that is an Indian satellite.
Having own satellite doesn't mean that the satellite could be over the disaster area all the time, since satellite constantly move in orbit.
Hence the setup of "International Charter on Space and Major Disasters" program, so that member could provide each other with satellite service. Win-win !!

China Aerospace Science and Technology Group
Today

At 11:57 on July 26, China used the CZ-2C carrier rocket at the Xichang Satellite Launch Center and successfully sent three satellites of the Yaogan-30 Group 05 into orbit. The launch was a complete success.

The CZ-2C carrier rocket that carried out this launch mission was developed by the First Institute of China Aerospace Science and Technology Corporation. The rocket is the first "golden rocket" in China to successfully perform missions in all three launch sites in the interior. This launch is also the first aerospace launch mission performed by this type of rocket this year.

Yaogan-30 05 satellites are mainly used for electromagnetic environment detection and related technology verification.

This launch is the 54th launch of the Long March II C series launch vehicle and the 308th flight of the Long March series of launch vehicles.

'Group 5' means Yaogan-35 or Yaogan-30-5?
The way I understand it, one can think of Yaogan-30 as a type of satellite technology, and it come in group/constellation of 3 satellites flying in formation. Group 5 would refer to the fifth group of Yaogan-30 type of constellation of satellites.

The first Yaogan satellite launched in 2006 and the constellation saw a steady launch cadence through 2016, operating three types of satellites: optical reconnaissance spacecraft with a ground resolution exceeding one meter, Synthetic Aperture Radar Satellites for day-and-night, all-weather imaging capability and formation-flying trios of electronic intelligence satellites to track foreign vessels and intercept communications.​

From Henry Kenhmann at the East Pendulum on 2019.07.26:

The 5th Yaogan YG-30 triplet, which are Chinese wiretapping satellites, was put into Low Earth Orbit (LEO) at altitude of 600 kilometers at 35 degree this morning (7/26) at 11:57 Beijing time by a Long March CZ-2C Y37 rocket. Grille wings were added on the first stage to control its fall in an area of 100 meters × 100 meters.

China successfully tests accurate landing of rocket debris
Source: Xinhua| 2019-07-29 00:06:36|Editor: yan

BEIJING, July 28 (Xinhua) -- China has successfully tested the technology that can accurately control the landing site of falling rocket parts, making progress toward reusable launch vehicles in the future, China Aerospace Science and Technology Corporation (CASC) said on Sunday.

The CASC said that the test was carried out following a Long March-2C rocket launched on Friday, and focused on grid fins which are like "wings" on rocket core part to increase precision in control of its landing location.

According to experts from the CASC, the rocket' flight trajectory is designed to avoid densely populated areas. But after completing the mission, the rocket debris falls under no control with a wide range of landing points which sometimes involve inhabited areas.

In order to ensure the safety of people's lives and property, the currently practice is to evacuate people to the safety zone before each mission, which is not only inconvenient for the local people, but increases the cost and task difficulty.

The success of the test is of great significance for improving China's inland rocket landing safety, minimizing the inconvenience to the local people, as well as promoting the follow-up development of carrier rockets' controllable recovery, soft landing and reuse, according to He Wei, an official with the CASC.

"The swinging grid fins were used to control the rocket debris' direction and attitude, much like the wings of the debris," said Cui Zhaoyun, the deputy chief designer of Long March-2C rocket. The landing site control of large and medium rockets is much more difficult than that of small rockets, he added.

Clear pictures of 24 catastrophic events shared with other countries and regions

China has deployed its satellites to monitor more than 30 major natural disasters around the world since the start of last year, offering help to affected nations and regions, according to a key figure in the project.

Guo Chaohui, a senior engineer at the China Center for Resources Satellite Data and Application, said on Sunday that the center arranged for Chinese satellites to take pictures and collect data from places that suffered from disasters upon receiving notification from the International Charter on Space and Major Disasters system and then provided the images to related nations and regions.

Chinese satellites took clear pictures in 24 of the disasters, including an earthquake in Indonesia last year and a cyclone that ravaged South Africa and Mozambique in April. In the other cases, the satellites failed to generate images due to natural interference such as thick clouds, he said.

"Currently, there are five Chinese satellites-the Gaofen 1, 2, 3 and 4 high-resolution Earth-observation satellites as well as the weather satellite Fengyun 3C-that are available for duties under the charter," Guo said.

Over the past two weeks, China's satellites took photographs of flood-stricken regions in India. China provided those images, together with previously taken pictures of the same places, to the Indian Space Research Organization to assist with the neighboring nation's recent flood relief efforts.

Vivek Singh, a spokesman for the space research group, told Xinhua on Thursday that India appreciated China's help in the disaster-relief efforts and that such mutual assistance was a good example of international cooperation.

As of Sunday, the death toll in India's flood-hit states had risen to more than 200. At least 11 million people have been directly affected.

The International Charter on Space and Major Disasters is a worldwide collaboration platform, through which satellite data are made available for the benefit of disaster management. It has 61 contributing satellites operated by 17 charter members, including the European Space Agency and United States Geological Survey.

China signed the charter in May 2007 and first called for assistance under the charter in July of that year when devastating floods ravaged central and eastern parts of the country, according to the China National Space Administration.

To date, China has invoked the charter 24 times and obtained a significant amount of satellite data for post-disaster relief efforts, according to information published on the charter's website.

The most recent time China activated the charter was in June last year when it asked for assistance to monitor a serious forest fire in the Inner Mongolia autonomous region.

For its part, China has offered satellite images that have helped in many natural disasters, such as the forest fires in southeast Australia in 2009, floods afflicting Pakistan in 2010 and the earthquake and tsunami that hit Japan in 2011. The nation also assisted multinational efforts to search for the missing Malaysia Airlines Flight MH370 in 2014, the Chinese space administration said.

A Russian law was approved July 26 that sets forth cooperation between Russia and China on using GLONASS and BeiDou for peaceful purposes.

According to the RosCosmos website, the law was approved at a meeting of the Council of Federation of the Federal Assembly of the Russian Federation. The law is officially named, “On ratification of the agreement between the Government of the Russian Federation and the Government of the People’s Republic of China on cooperation in the use of GLONASS and Beidou global navigation satellite systems for peaceful purposes.”

An intergovernmental agreement was signed on Nov. 7, 2018, in Beijing during the 23rd regular meeting of the heads of government of Russia and China. The agreement creates an institutional and legal framework for cooperation in the development and manufacture of civil navigation equipment using GLONASS and Beidou systems.

It also establishes cooperation in the development of Russian-Chinese standards for the application of navigation technologies using both systems — in particular, standards for the control and management of traffic flows across the Russian-Chinese border. The border is 4,200 kilometers (2,615.5 miles) long — world’s sixth-longest international border.

Under the agreement, the two countries plan to place in their own countries measuring stations for the other country’s GNSS, on a reciprocal basis.
