China developing atomic clock for Beidou system

2017-07-29 08:55

Xinhua Editor: Mo Hong'e

China is developing a new generation of atomic clock, which it aims to use on the Beidou Navigation Satellite System, according to China Aerospace Science and Technology Corporation (CASTC) Friday.

The microwave mercury ion clock is currently one of the most accurate tools for measuring time by tracking atomic movement in the microwave range, said Wang Nuanrang, project leader at the CASTC.

It can provide extremely precise measurements of time that can be used in the fields of deep space exploration and satellite navigation.

Wang said that scientists will establish an experimental mercury ion clock system to conduct scientific tests within the next four years, promoting the development of the Beidou system.

Since 2012, China's self-developed Beidou system has provided navigation, time and text messaging services in the Asia Pacific region.

By 2020, Beidou satellites will form a complete global satellite navigation system, according to China Satellite Navigation System Committee.

Hence "a new generation of atomic clock" blabla...

India's satellites are nothing but assemblies of imported parts and components.

It will be decades before our Indian friends are able to make, for example, their own chips. Any any any chips!

China to preload BeiDou for most motorcycles by 2018

2017-08-01 08:44

Xinhua Editor: Mo Hong'e

Most motorcycles made in China are expected to be preloaded with BeiDou navigation system by 2018, according to a meeting on the promotion of BeiDou on Monday.

During the 13th Five-Year Plan period (2016-2020), more than 20 million motorcycles equipped with BeiDou are expected to be put on the market, over half of which will be aimed at overseas markets.

At the meeting, China's 15 major motorcycle producers reached consensus on reaching these targets.

Promoting BeiDou for car networking usage will help improve traffic management, relieve congestion, cut down robbery and motivate energy saving and environmental protection, said Bo Yumin, chief engineer of the Certification and Accreditation Administration of the People's Republic of China.

"BeiDou is ready for civic use. It will help to improve the efficiency of accident rescue, and reduce loss of life," said Qiao Yueshan, deputy director of information technology department of the Ministry of Industry and Information Technology.

China launched the 23rd satellite last year for BeiDou Navigation Satellite System (BDS) to improve the stability of this self-developed navigation system, and prepare it for global coverage.

Sir, can you give an explanation about the altitude of BeiDuo's satellites, it's accuracy in positioning, and final numbers of satellites which will be deployed into orbits?
Also a comparison with GPS in terms of accuracy, stability and accessibility. I'd like to know in which band/frequency does this system works and would Chinese scientists module it's frequencies with deliberative errors like AS or SA of GPS? Is it even accessible in other countries?
Thanks in advance.

[Update] Yaogan-6 caught on camera tumbling

The Yaogan-6 remote sensing satellite, likely also used as a military reconnaissance satellite, was launched by a CZ-2C rocket from China's Taiyuan space center on 22. April 2009.
It is likely an radar reconnaissance satellite.
The second satellite in this series, Yaogan 13, was launched on 29. November 2011 also from Taiyuan space center.
​

May 2016

Yaogan 18 and Yaogan 6 have orbital characteristics very similar to Yaogan 13 and Yaogan 23.
They are also launched by the same CZ-2C launcher.
Their near identical equatorial crossing times of 09.56 AM and 10.01 AM shows that the Yaogan-18 is a replacement for the Yaogan 6 satellite.
These may also carry the same improved SAR sensor carried by the Yaogan 13 and Yaogan 23 satellites

Four rockets in 1 week to be launched

2017-08-31 09:18

China Daily Editor: Li Yahui

Multiple satellite lifts will set a record for single type of carrier, designer says

China Aerospace Science and Industry Corp, a major space contractor, said on Wednesday that it will launch four Kuaizhou 1A rockets within one week in early 2018.

Each of the rockets will lift a remote-sensing satellite into orbit for a client, said Zha Xiongquan, a senior rocket designer at CASIC and vice-president of Expace Technology, a subsidiary of CASIC that provides commercial launch services.

He did not disclose the name of the client or the timetable for the missions, saying only that they will "definitely set a world record for launch frequency for a single model of carrier rocket".

No other rockets in the world have been used four times within one week, he said.

Zha made the remarks at the Third China International Commercial Aerospace Forum, which was sponsored by CASIC in Wuhan, Hubei province. Nearly 400 government officials, company representatives and industry experts from more than 20 nations, including the United States, Russia and Iran, attended the event and discussed technological developments and business opportunities in the space industry.

The Kuaizhou 1A, a solid-fuel carrier rocket developed by the CASIC Fourth Academy in Wuhan, has a liftoff weight of 30 metric tons and is capable of sending a 200-kilogram payload into a sun-synchronous orbit, or a 300-kg payload into a low-Earth orbit. Unlike most Chinese carrier rockets, it uses a transporter-erector-launch vehicle for liftoff rather than a fixed launchpad.

The first flight of the Kuaizhou 1A, carrying three small satellites, was in January. It was launched at the Jiuquan Satellite Launch Center in northwestern China.

The CASIC Fourth Academy began to develop Kuaizhou-series solid-fuel rockets in 2009 in hopes of presenting a low-cost, quick-response rocket family to the commercial launch market. It has launched three of the rockets.

Zha said a new-generation－the Kuaizhou 11－is under development and will make its first flight next year to send six satellites into orbit. He added that the rocket is undergoing testing.

According to the academy, the Kuaizhou 11 will have a liftoff weight of 78 tons and will be capable of placing a 1-ton payload into a sun-synchronous orbit at an altitude of 700 km, or a 1.5-ton payload into a low-Earth orbit at an altitude of 400 km.

The academy is also building the Wuhan National Space Industry Base, which will have an area of 68.8 square kilometers, in Wuhan's Xinzhou district. CASIC will invest 1.7 billion yuan ($258 million) in the base to build production and assembly plants for Kuaizhou rockets. It said it plans to make about 20 rockets at the base each year.

The CASIC Second Academy will also invest 300 million yuan to construct a research, development and manufacturing complex at the Wuhan base for making small satellites.

The aerospace company has said it will launch 156 small communications satellites into low-Earth orbit, at an altitude of 160 to 2,000 km, from 2018 to 2025. They would form a network capable of global coverage.

Kuaizhou-11 to send six satellites into space

2017-08-31 09:20

Xinhua Editor: Gu Liping

China's Kuaizhou-11 solid-fuelled carrier rocket will send six satellites into space in its first mission, according to the rocket's developer and producer China Aerospace Science and Industry Corp (CASIC).

The company announced the news Wednesday at the Third China (International) Commercial Aerospace Forum in Wuhan, capital of central China's Hubei Province.

The Kuaizhou-11 rocket will be launched via a mobile launch vehicle. With a lift-off mass of 78 tonnes, the rocket was designed to launch low-Earth and Sun- synchronous orbit satellites.

Kuaizhou, which is Chinese for fast ship, is a low-cost solid-fuelled carrier rocket with high reliability and a short preparation period.

Globally, the launch cost of small commercial carrier rockets usually ranges from 25,000 to 40,000 U.S. dollars per kilogram of payload, according to a CASIC spokesperson.

The spokesperson said Kuaizhou rockets are price competitive. The launch cost of the Kuaizhou-1A was less than 20,000 U.S. dollars per kg of payload, while Kuaizhou-11 rocket is less than 10,000 U.S. dollars.

In January, the Kuaizhou-1A rocket sent three satellites into space in its first commercial mission.
