Plus, Beidou has to be commercialized. If no body uses it, how will it profit from civilian application?

Imagine how many billion chips would be produced, and produced in China, to be installed in apples, oranges and others.

Overtime, Beidou must drive the GPS from the market. Any sane Chinese citizen would prefer a domestic positioning system than a foreign one.

I think Beidou has an excellent pitch for provision of commercial / military services to overseas markets where the governments do not want to have a 100% GPS dependent positioning functions.

Generallyl Beidou is provided free of charges to commercial users with basic functions. It has a strong market for logistic tracking in the transportation sector like airlines. shipping companies, taxis, truckers etc

The successful key problem solving endeavours by Chinese Scientists will bring a Quantum Communicaion Satellite to the launching pad in 2016 as scheduled

量子科学实验卫星发射在即?攻关试验均已完成--科技--人民网

　　2016年，天空中将会多出一颗耀眼的星，而它就是即将发射的“量子科学实验卫星”。

　　“前面的攻关试验都已经做完了。”中国科大微尺度物质科学国家实验室研究员彭承志说，量子科学实验卫星将如期发射。

　　这意味着，量子通信将具备覆盖全球范围的能力。“不过，量子科学实验卫星是一颗低轨卫星，只能在晚上进行量子通信，空间覆盖能力和应用都还比较有限。”彭承志说，为了提高量子通信的范围和应用能力，他们可能还会考虑量子星座的研制。

　　迈出量子通信第一步

　　随着网络通信的飞速发展，账号保护、传送安全等成为人们日益关心的问题。作为以量子力学基本原理为基础的全新通信技术，量子通信被视为可以解决人们的担忧、无条件保障通信安全的最有效方式。

　　而如何让这一方式更好地服务于广大用户，一直是学界研究的热点。中科院院士、中国科学技术大学教授潘建伟带领团队，用辛苦和努力浇灌了一朵量子之花。

　　2012年2月17日，是让团队成员、中科院量子技术与应用研究中心副主任赵勇铭记在心的日子。当天，历时18个月建设的“合肥城域量子通信试验示范网”终于完成了。

　　这是全球首个城域量子通信试验示范网，有了这一安全保障，示范网用户传递的信息内容就会变得不可窃听、复制或破译。

　　研制量子通信网络终端设备，研制量子通信微光探测核心器件，研制量子通信网控设备等产品……前期的工作做足后，拥有一个产品和技术的试验床，就显得有点迫切。

　　“我们需要一个具有稳定性和安全性的更大的平台来检测通信，同时积累量子通信网络的建设和运维经验。”赵勇说。

　　合肥示范网应运而生，建成的示范网有46个节点，网络覆盖合肥市主城区，用户涵盖省市政府机关单位、金融机构、研究院所等。而直到现在，这些单位都是这一平台上的创新参与者。

　　将通信安全距离扩展至更远

　　如果说合肥示范网的建立是要建设一个技术试验床，那么，今年3月份投入使用的济南量子通信试验网则是面向用户日常应用的，希望更加贴合不同使用单位的要求。

　　目前，济南量子网络有90多家用户单位，可以通过网络内量子通信集控站和终端，实现安全的语音和视频通信、安全的文件传真以及安全的数据传输。

　　“我们的平台可以承载上千用户。”赵勇说，“网络目前是免费提供给用户使用的，试验网的目的是通过用户的使用来进行相关行业应用模式的探索。”

　　济南网的顺利运行，标志着量子通信城域网技术已经发展成熟。

　　“量子通信网络需要在更大范围里，通过更多的用户体验进一步验证其稳定性，提高其可用性。”中国科大微尺度物质科学国家实验室研究员陈宇翱表示，只有具备了稳定性，才会拥有更多的用户。

　　记者了解到，建设中的量子通信“京沪干线”连接北京、济南、合肥、上海，全长2025公里，提供4城市间网状8Gbps加密应用数据传输业务。

　　“目前主要的使用对象还是银行、证券公司等一些金融机构。”陈宇翱说，北京、上海城域量子通信网将分别于今年年底和明年夏天建成。

　　陈宇翱告诉记者，2025~2030年，覆盖全国的量子通信网络也有望建成，“我们希望能将安全距离扩展得更远，并且通过京沪干线来探索一定的商业盈利模式，将量子通信产业化”。

　　拓展量子应用领域

　　在潘建伟等人看来，成功就是解决一个又一个问题。

　　量子科学实验卫星的研发亦是如此。研制一颗卫星，需要考虑很多问题，包括如何提高精度，将量子信号从天上传下来以及卫星发射以后的空间适应性问题。

　　尽管过程满是艰难，所幸的是，这些问题都已得到很好的验证。现在，团队成员们在期待卫星发射的那一刻。

　　不过，对于团队的研究人员来说，努力并没有到此为止。目前量子通信完成的还是最简单的点对点的信息传递，真正要组网的话，还需要一段时间。

　　彭承志还表示，日后建成的量子通信网络，要致力于与既有经典网络的融合，“比如说加密这一块，我们要提高网络的实用性，让更多的外围企业参与进来”。

　　此外，通过量子通信的发展来带动量子测量和量子计算等技术的发展，也是这个团队的期望，在他们看来，未来，“量子技术大有可为”。

China Plans BeiDou Ground Station in Antarctica : GPS World

China plans to build a BeiDou station in Antarctica this summer, according to a report in the Sydney Morning Herald. China’s official Xinhua news agency disclosed the plans.

The facility at Great Wall station in Antarctica will include receivers, auxiliary equipment and a reference station key to improving BieDou’s accuracy, according to the Chinese enews.com website.

Project leader Wu Xuefeng said the BeiDou facility would greatly improve China’s Antarctic mapping autonomy and improving the system’s precision.

The BeiDou facility will join others, including Norway’s Trollsat, strategically located in Antarctica to fit that country’s global networks, but which some claim breach the Antarctic Treaty. The treaty says “Antarctica shall be used for peaceful purposes only” and prohibits activities of a military nature.

Norwegian Bard Wormdal, author of The Satellite War, told Fairfax Media, “The Chinese military wants to use BeiDou for instance for guiding all sorts of missiles. A BeiDou base in Antarctica makes the system more reliable and precise.” He first raised alarm over the Norwegian satellite base at its Troll Antarctic station, which he found had been used by the U.S. National Geospatial Intelligence Agency.

Russia has three GLONASS ground stations on the continent.

ZTE smartphones to carry BeiDou chips
By Chu Daye

Report says enables devices to use local BDS navigational service

A Shanghai high-tech company has rolled out a navigation chip utilizing the BeiDou Navigation Satellite System (BDS) service that will be used on over 1 million smartphones made by Chinese smartphone maker ZTE from early 2015, Shanghai-based newspaper Wen Hui Bao reported over the weekend.

Experts said the chip, a key component in the navigation service, will help to promote the civil and commercial use of BDS in China.

Shanghai Beiga Satellite Technology Co displayed the newly developed chip on Thursday at an industry exhibition in Shanghai for promoting the civilian use of military technologies, according to the report.

Wang Yong ping, general manager of Beiga, said they are improving the chip that debuted at the exhibition and will start mass production and consolidate it into about 1 million ZTE smartphones from next March, the report said.

Wang further predicted the figure could hit 10 million by the end of 2016.

ZTE could not be reached for confirmation by press time over the weekend.

A chip that can be used on smartphones is a technological improvement and positive for the whole industry due to the chance of winning orders to be used on a vast number of devices, Xiang Ligang, CEO of industry information portal cctime.com, told the Global Times Sunday.

"In China, the civilian use of the Global Positioning System (GPS) has some limitations. For instance, it cannot recognize the differences between main roads and side roads with its accuracy performance lingering at around 10 meters. BDS is said to have better performance in this regard, which boosts its value for Chinese consumers," Xiang said.

Previous chips using the BDS were too large and consumed too much energy to be logical for daily use, Wen Hui Bao reported.

China started to build its own space-based positioning, navigation and timing system in 2000 as an alternative to GPS, which is maintained by the US government and is freely accessible to anyone with a GPS receiver.

The BDS network, which initially was for military usage and currently consists of 16 operational satellites, started providing public service to the Asia-Pacific region in December 2012.

Gu Zhengxi, deputy general manager of Beijing-based CenNavi Technologies Co, a traffic information service provider based on satellite technology, said the majority of chips sold in the domestic market are so called dual-mode chips, receiving both signals sent from satellites belonging to the BDS as well as the GPS system.

China is steadily pushing forward the usage of its homegrown BDS.

China plans to cooperate with several countries, including Mexico, Israel and Sweden, to expand the reach of its BeiDou navigation satellite system, China National Radio reported on October 22.

By the end of 2013, BDS had been installed on over 50,000 Chinese fishing vessels with subsidies from the government, Reuters reported on July 27.

"Strong policy support and the necessity of a homegrown system for national defense indicate BDS will carve out market share from the domestic market dominated by GPS," Gu told the Global Times Sunday.

"The proliferation of its application, especially in the field of civilian use, will help the system to achieve the economy of scale at an earlier date and bring down its cost," Gu said.

In addition to GPS and BDS, there are other systems in use or under development, such as the Russian Global Navigation Satellite System (GLONASS) and the EU's Galileo positioning system, media reports said.

Congrats to China! China can't afford to to be at the mercy of others in something as vital as this.

I'm curious but is Beidou operating on the frequency that the Europeans originally wanted for Galileo? If so, this is all very hilarious.

Brief history - China originally partnered with Europe in the Galileo project and paid handsomely to do so. A little later, it turned out the Europeans were only too happy to accept Chinese money but were not actually willing to give China any strategic control over the project or the satellites once finished.

So China said "screw you" and developed Beidou and put it in orbit and got it operational faster than Galileo, thereby claiming the unused frequency the Euros had been eyeing (int'l essentially states - first to use = owner), which made the Euros come crawling back, begging for their frequency. I think China told them to screw off again if I'm not mistaken. How's that for justice.

It was the world's first mission to the Moon and back in some 40 years, with China becoming the third nation to do so after the Soviet Union and the United States.

After two orbital transfers, the service module re-entered the elliptical orbit with an apogee of 540,000 km and a perigee of 600 km.

During the flight, the service module again performed orbital transfer actions twice, and flew along the pre-set Earth-moon transfer orbit. On Nov. 23, it reached the perilune and with the lunar gravity it was able to undertake the orbit maneuver to fly to the L2 point.

An indigenous GPS system is a must for a country as big as China. You cannot trust others on this very significant national security matter. Cooperation on equal terms are welcome, though.
