Firma Rocket Lab jest firmą amerykańską, tyle że posiadającą oddział w Nowej Zelandii i stamtąd wystrzeliwującą swoje rakiety. Dlatego wszelkie zestawienia zaliczają te starty do amerykańskich.
Dokonałem w zestawieniu korekty

TAIYUAN, June 11 (Xinhua) -- China successfully sent an ocean observation satellite into orbit from the Taiyuan Satellite Launch Center in north China's Shanxi Province on Thursday.

A Long March-2C rocket, carrying the satellite HY-1D, lifted off at 2:31 a.m. (Beijing Time), according to the China National Space Administration (CNSA).

The new satellite will form China's first satellite constellation for marine civil service together with HY-1C, which was launched in September 2018, and double the current ocean observation data, according to CNSA and the Ministry of Natural Resources.



The satellite constellation is expected to improve China's capabilities in observing ocean color, coastal resources and ecological environment, and ramp up support for meteorology, agriculture, water conservation and transportation.

It will also be of great significance to coping with global climate change and building an ecological civilization.

HY-1D, China's fourth remote-sensing satellite for ocean observation, carries five payloads that have similar functions as HY-1C. A scanner can observe ocean color globally, and measure the surface temperature of the seas, every day, with a spatial resolution of 1.1 km.

The imager can obtain coastal water environment, coastal zone and ecological environment of rivers and lakes with a spatial resolution of 50 meters, every three days.

It is also equipped with an automatic identification system for ships.

The data will be used for resource and environmental surveys, and to facilitate marine disaster prevention and mitigation, sustainable utilization of marine resources, early warning for marine ecology, and environmental protection.

The satellite was developed by the DFH Satellite Co. Ltd. under the China Academy of Space Technology, and the carrier rocket was produced by the China Academy of Launch Vehicle Technology.

Thursday's launch was the 334th by the Long March rocket series. Enditem

China launches ocean monitoring satellite

(...) The China Academy of Launch Vehicle Technology, or CALT, said engineers introduced changes to the Long March 2C’s payload fairing for this launch. CALT is China’s primary state-owned launch vehicle manufacturer.

After jettisoning from the launcher a few minutes after liftoff, the payload shroud on Chinese rockets typically falls back to the ground uncontrolled. Built with lightweight thin walls to reduce the mass, the two-piece payload fairing can lose its shape during descent.

Chinese officials added an X-shaped beam to reinforce the fairing structure to help the nose cone avoid damage during the fall back to Earth. Engineers also installed an optical fiber sensor on the fairing to measure strain, stress and other parameters during the fairing’s descent back through the atmosphere, according to CALT.

The data will help inform future upgrades to the fairing, officials said.

Launches from most Chinese spaceports, including Taiyuan, drop booster stages and payload fairings on land, rather than over the ocean. (...)

The Haiyang 1D satellite carries five instrument payloads.

The satellite will observe ocean color, a measurement that helps scientists track pollution and natural ocean constituents such as chlorophyll. Haiyang 1D will also measure sea surface temperatures, image coastal waters, and detect identification signals from ships. The measurements will be used by weather forecasters, farming operations, and water conservation, transportation and environmental protection authorities, according to China’s government-run Xinhua news agency.

HELSINKI — China launched the Haiyang-1D ocean observation satellite Wednesday with the country’s 13th orbital launch of 2020.

The two-stage hypergolic Long March 2C lifted off at 4:31 p.m. Eastern from the Taiyuan Satellite Launch Center, north China. Indication of the imminent launch attempt came from airspace closure notices days ahead of launch.

The first sign that launch had occurred came just under half an hour after liftoff when launch success was confirmed (Chinese) by the state-owned China Aerospace Science and Technology Corp., the main contractor for the country’s space programs. (...)

JIUQUAN, June 17 (Xinhua) -- China launched a new Earth observation satellite from the Jiuquan Satellite Launch Center in northwest China at 3:19 p.m. Wednesday (Beijing Time).



The satellite Gaofen-9 03, sent into orbit by a Long March-2D carrier rocket, is an optical remote-sensing satellite with a resolution up to the sub-meter level.

The satellite will be mainly used for land survey, city planning, land right confirmation, road network design, crop yield estimation and disaster prevention and mitigation, as well as providing information for the construction of the Belt and Road.

Via the same carrier rocket, two other satellites were also sent into space. One of them, developed by Zhejiang University, will be used to test pico-satellite and nano-satellite technologies.

The other satellite, developed by Beijing-based China HEAD Aerospace Technology Co., will be used to collect global information on ship and flight statuses and the Internet of Things.

Wednesday's launch was the 335th mission of the Long March rocket series. Enditem

Gaofen-9 joins Earth observation system

Gaofen satellites are part of a civilian China High-resolution Earth Observation System (CHEOS). The satellites are used for land surveying, urban planning, road network design, agriculture, disaster relief and other uses, according to Chinese media.

The program was initiated in 2010 to provide all-weather, all-day coverage with optical and synthetic aperture radar satellites. CHEOS may also include airborne and near-space systems such as stratospheric balloons.

Computer generated renders of the Gaofen-11 satellite, launched in July 2018, suggest a large aperture high resolution Earth observation satellite with resemblance to U.S. Keyhole-class satellites.

The Yaogan satellite series is the military reconnaissance counterpart which utilizes similar technology and platforms.

A Gaofen Earth-imaging satellite and two secondary payloads launched Wednesday aboard a Chinese Long March 2D rocket.

The Long March 2D launcher took off at 0719 GMT (3:19 a.m. EDT) Wednesday from the Jiuquan space base in the Inner Mongolia Autonomous Region located in northwestern China.

The launch occurred at 3:19 p.m. Beijing time, marking China’s 14th orbital launch attempt so far 2020. Two of the 14 space launch attempts have been failures.

China’s state-run Xinhua news agency said the two-stage Long March 2D rocket launched the Gaofen 9-03 Earth observation satellite, which will be “mainly used for land survey, city planning, land right confirmation, road network design, crop yield estimation, and disaster prevention and mitigation.”

The Gaofen 9-03 spacecraft is the third satellite to launch in China’s Gaofen 9-series, following missions launched in 2015 and on May 31 of this year. It is not clear whether the Gaofen 9 satellites are identical or only share a name, but Chinese state media reports associated with each launch indicated the payloads all carried optical Earth-imaging cameras with a resolution of better than 3.3 feet, or 1 meter.

China says the Gaofen series of satellites are managed by civilian officials. The Gaofen fleet includes satellites with optical, infrared and radar imaging observatories.

Wednesday’s Long March 2D launch also carried two smaller satellites into space, Xinhua said.

One of the secondary payloads launched Wednesday was the HEAD 5 microsatellite for a Beijing-based private company named HEAD Aerospace, which is deploying a fleet of small spacecraft to track ships and aircraft.

Another rideshare passenger was the Pixing 3A smallsat from Zhejiang University, which is designed to test picosatellite and nanosatellite technologies, according to Xinhua.

China launches last BDS satellite to complete global navigation constellation
Source: Xinhua| 2020-06-23 15:47:14|Editor: huaxia

XICHANG, June 23 (Xinhua) -- China launched the last satellite of the BeiDou Navigation Satellite System (BDS) on Tuesday, marking the completion of the deployment of its own global navigation system.

The satellite, the 55th in the family of BeiDou that means "Big Dipper" in Chinese, was launched at 9:43 a.m. (Beijing Time) and sent into the preset orbit by a Long March-3B carrier rocket from the Xichang Satellite Launch Center in southwest China's Sichuan Province.

The mission, the 336th by the Long March rocket series, was a "complete success," the launch center said.

The satellite, designated to enter the geostationary earth orbit (GEO), was the last one of the BDS-3 system, which started to offer countries and regions along the Belt and Road as well as the world basic navigation service in December 2018.

BDS is one of four global navigation satellite systems in the world. The other three global navigation systems are GPS of the United States, Galileo of the European Union, and GLONASS of Russia.

China has been actively encouraging the cooperation and exchanges between the BDS system and other navigation systems in fields such as construction and application, strengthening compatibility and interoperability, resource sharing, and providing users with more qualified, diversified, safe and reliable services.

Compared with other global systems in the world, the design of the BDS constellation is unique, including medium earth orbit (MEO), inclined geosynchronous orbit (IGSO) and GEO satellites.

The BDS-3 system consists of a total of 30 satellites, including 24 MEO satellites, three IGSO satellites and three GEO satellites.

The three GEO satellites, including the newly launched one, can help significantly enhance the overall technical indicators of the BDS-3 system, according to the satellite developer China Academy of Space Technology (CAST).

They feature two distinctive creations of the BDS system -- active positioning and short message communication, CAST said.

The short message communication capability of the BDS-3 system has been improved 10 times. Users of the system can send a message of 1,200 Chinese characters at one time, as well as pictures, a useful function in emergencies.

Active positioning, employing radio measurement technology, can provide the locations of the users, not only to themselves, but also to relevant parties who are monitoring the users' whereabouts, through the joint efforts of two GEO satellites.

The function is widely used in search and rescue, fishing and other fields to help guarantee people's safety.

The BDS system provides navigation signals of multiple frequencies, and is able to improve service accuracy by using combined multi-frequency signals.

It also integrates navigation and communication capabilities for the first time, and can provide services of navigation, short message communication, satellite-based augmentation, international search and rescue, as well as precise point positioning.

"BDS provides time-and-space location benchmarks, which will have a great influence on the country's social and economic development, as well as people's lives," said Chen Zhonggui, chief designer of the BDS-3 satellites at CAST.

"It will also lay the foundation for new infrastructure construction, an important direction for China's development in the next stage," Chen said.

China started to explore a navigation satellite system suited to its national conditions in the 1980s, laying down a three-step strategy.

The BDS-1 project, the first step, also known as BeiDou Navigation Satellite Demonstration System, got official approval in 1994, when China was still facing an international technology blockade and domestic component manufacturers were not yet fully fledged.

The team started the exploration work with the solar arrays, recalled Fan Benyao, chief designer of BDS-1 at CAST.

Insisting on self-reliance, the older generation of the BDS team overcame a series of technical problems, including those relating to the Dongfanghong-3 satellite platform and key components that might affect the service life of the satellites.

BDS-1 was completed and put into operation in 2000 with the launching of two satellites, providing useful experience in the areas of construction and application, as well as training professionals for the following projects.

The second step was to construct the BDS-2 system, which started in 2004.

The team worked around the clock, at one point conducting 200-hour non-stop power-on tests at the launch site.

By the end of 2012, a total of 14 satellites, including five GEO satellites, five IGSO satellites and four MEO satellites, were successfully launched to complete the deployment.

The BDS-2 system is the world's first hybrid constellation, in which satellites in three kinds of orbits work in concert. It started providing regional services for users in the Asia-Pacific region in December 2012. Enditem

Commentary: China's BeiDou system primed for serving whole world
Source: Xinhua| 2020-06-23 17:19:17|Editor: huaxia by Xinhua writer Gao Wencheng

BEIJING, June 23 (Xinhua) -- China launched the last satellite of the BeiDou Navigation Satellite System (BDS) on Tuesday, marking the completion of the country's independently developed orbital navigation network, and a landmark step of its peaceful exploration of space.

The BeiDou network, a major infrastructure independently constructed and operated by China, can better meet the demands of the country's national security, economic as well as social development. It can also provide more stable and reliable services, as well as an alternative to the U.S.-owned Global Positioning System (GPS) for global users.

Given national security concerns due to the GPS's dominance, China is not the only one in the world that strives to develop its satellite navigation systems. For many years, the European Union, Russia and others have all been working on their own projects.

Thus one of the BDS's prominent principles is indigenous innovation. Core technologies as well as key components and software of the BDS are independently developed and manufactured by China.

Such an independent drive in the field of scientific and technological research and development echoes the very spirit pursued by many Chinese scientists who once dedicated themselves to the "Two Bombs, One Satellite" project during the Cold War era when China was under nuclear threats by some major world powers.

In recent years, Washington has been stepping up its high-tech blockade against China. America's descending technological iron curtain has further underscored the importance of indigenous technological advancement in key areas, which is imperative to China's national security and development.

The BeiDou system also features openness and compatibility. The system provides open satellite navigation services free of charge, encourages international exchanges and cooperation, and strives to enhance compatibility and interoperability with other navigation satellite systems, so as to provide better services to users worldwide.

After 26 years of arduous work, the BDS has now earned a global reputation for its high-accuracy service and various service capabilities in positioning, navigation and timing, short message communication, and international search and rescue.

In a congratulatory video message, the United Nations Office for Outer Space Affairs Director Simonetta Di Pippo said: "The services provided by BeiDou are already driving social and economic development around the world."

Indeed, the BDS-based solutions have already been successfully adopted in such fields as land registration, precise agriculture, digital construction, monitoring and management on vehicles and ships, intelligent port management in regions like Asia, East Europe, and Africa.

Also, the BDS-enabled products have been exported to more than 100 countries, providing users with a variety of choices and enhanced application experience.

Thousands of years ago, the Chinese invented the compass, which had made long-range voyages on rough and vast seas possible, and helped usher in the Age of Discovery.

Today, the BDS network is primed for facilitating an even stronger global connectivity in this age of globalization, and helping countries worldwide to chart their own courses into a better future. Enditem

China launches final satellite to complete Beidou system, booster falls downrange
by Andrew Jones — June 23, 2020

HELSINKI — China launched a Beidou-3 navigation satellite late Monday to complete a project designed to provide military independence and immense commercial value. (...)

“But with four GNSS soon to be live, I am sceptical over how much leverage China will get in civil/commercial terms with other parts of the world given that other states and companies can go shopping for other infrastructure if China decides to not allow them to use it as they wish,” Bowen says.

Bowen states that the primary benefit of the system is for modernizing China’s military forces and integrating spacepower into its terrestrial strike forces and long-range conventional missile systems.

“However, to truly capitalise on this the People’s Liberation Army needs to distribute a lot of receivers which will take time, and of course its modernizing forces need to get used to conducting high-intensity space-enabled military operations. America and its allies have 30 years of experience in this and have developed a lot of skills and institutional memory on how to use GPS in combat. China can’t claim to have that – not yet anyway.” (...)

China launches final Beidou navigation satellite

(...) The Long March 3B rocket launch puts China on the verge of completing the deployment of the Beidou program’s third-generation, or BDS-3, satellite network. It was be the 35th BDS-3 satellite launched since 2015 — including test and validation satellites — and the 59th Beidou spacecraft launched since 2000.

China has reportedly spent approximately $10 billion on the Beidou program, which the Chinese government approved for development in 1994.

The Beidou network, named for the Chinese word for the Big Dipper constellation, includes satellites positioned in three different types of orbits. The Beidou system needs at least 30 satellites operating at any one time for uninterrupted global navigation service.

In December, China launched the last of 24 operational satellites into a medium-altitude orbit more than 13,000 miles (21,000 kilometers) above Earth, similar to the orbits used by GPS, Glonass and Galileo satellites.

But unlike the other global navigation systems, the fully-operational Beidou network includes six spacecraft in geosynchronous orbits more than 22,000 miles (nearly 36,000 kilometers) above Earth, with three permanently over the equator and three others in inclined orbits that swing north and south of the equator during each 24-hour orbit.

China launched three satellites into inclined geosynchronous orbits last year, and the final Beidou spacecraft launched Tuesday is the third of three to be permanently stationed over the equator.

The satellite delivered to orbit Tuesday will use its on-board propulsion to circularize its orbit more than 22,000 miles over the equator in the coming weeks before ground controllers put the spacecraft through testing. It is expected to enter service in a few months.

The first four Beidou satellites broadcast positioning and timing signals over China. The second phase of the Beidou system, known as BDS-2, was completed in 2012 to provide navigation services over the broader Asia-Pacific region.

As of this week, China’s Beidou network had 44 operational spacecraft, including BDS-2 and BDS-3 satellites. (...)
