China’s Beidou GPS system is as accurate as US GPS system


Beidou GPS SystemAt  the 2012 Forum of Astronautic Technology and Strategic Emerging Industries in Dalian City, Yang Qiangwen, Chief Engineer of China’s Beidou Satellite Navigation System, said that the system was as accurate as US GPS System. Its horizontal error is less than 10 meters while that high up in sky is less than 15 meters. In measuring speed, its error is less than 0.2 m/s.

China has developed the system over the past 10 years. Its first phase was formally completed in 2003. The three satellites operated satisfactorily. The last satellite for the second phase was launched on October 25 this year to complete a regional network of 16 satellites, in which 14 are providing services in their orbits. The whole system is operating smoothly and is able to provide formal services for the entire Asian-Pacific region.

The third phase, Beidou Global Navigation System will be completed by 2020.

According to estimates, the system is generating 100 billion yuan ($16 billion) revenue now. It is expected that its revenue will rise to 150 billion yuan ($24 billion) and 400 billion yuan ($64 billion) respectively by 2015 and 2020.

Major Chinese producers of the chips have made a breakthrough in the technology related to the chips. They have entered the second and even the third stage of development, and their products are equivalent in technology and functions to those of major companies abroad such as SiRF and uBlox.

Yang said that so far the chips produced by China were expensive and had to be improved through extensive use. He expects that by 2015, China will have its own intellectual property for the chips and the functions of its chips will meet international technical standards then.

He said that Beidou faces cruel international struggle for resources, position and market. There are a limited number of frequencies for navigation systems and the best of them have been taken by the US and Russia. China and Europe who began development of their systems later, have difficulties due to the limited number of channels. The have to conduct negotiation and discussion and do a lot of work to get more and better channels.

Yang also mentioned the possibility of cooperation with the US and Russian systems, but stressed that China had never wavered, and would persist in developing its system independently.

He said that Pakistan and Indonesia are much interested in the Beidou System while Laos, Myanmar, Mongolia and some other countries are also interested. Work is being done to provide the services of the Beidou System abroad.

Author of the book "Tiananmen's Tremendous Achievements" about how with the help of Tiananmen Protests, talented scholars with moral integrity seized power in the Party and state and brought prosperity to China.

There are also some changes for improvements of style. The new parts are Chapters 12-19 on events in China after the first edition was published: The fierce power struggle for succession between reformists and conservatives; Xi Jinping winning all elders’ support during his mysterious disappearance for 2 weeks in early September, 2012; and Xi Jinping Cyclone. Chan Kai Yee's new book: SPACE ERA STRATEGY: The Way China Beats The US An eye-opening book that tells the truth how the US is losing to China. The US is losing as it adopts the outdated strategy of Air-Sea Battle while China adopts the space era strategy to pursue integrated space and air capabilities: It is losing due to its diplomacy that has given rise to Russian-Chinese alliance. US outdated strategy has enabled China to catch up and surpass the US in key weapons: Hypersonic weapons (HGV) that Pentagon regards as the weapon that will dominate the world in the future. Aerospaceplane in China’s development of space-air bomber that can engage enemy anywhere in the world within an hour and destroy an entire aircraft carrier battle group within minutes. Anti-satellite (ASAT) weapons, anti-ASAT weapons, stealth aircrafts, drones, AEW&C, etc. The book gives detailed descriptions of China’s weapon development based on information mainly from Chinese sources that the author monitors closely. U.S. Must Not Be Beaten by China! China is not a democracy. Its political system cannot prevent the emergence of a despotic leader or stop such a leader when he begins to bring disasters to people. A few decades ago, Mao Zedong, the worst tyrant in world history did emerge and bring disasters to Chinese people. He wanted to fight a nuclear war to replace capitalism with communism but could not bring nuclear holocaust to world people as China was too weak and poor at that time. If a despot like Mao Zedong emerges when China has surpassed the US in military strength, world people will suffer the misery experienced by Chinese people in Mao era. China surpassing the US in GDP is not something to worry about as China has the heavy burden to satisfy its huge population, but China surpassing the US in military strength will be world people’s greatest concern if China remains an autocracy. US people are of much better quality than Chinese people. What they lack is a wise leader to adopt the correct strategy and diplomacy and the creative ways to use its resources in developing its military capabilities. I hope that with the emergence of a great leader, the US can put an end to its decline and remain number one in the world.
