Original title: Beidou system officially entered the world era!

According to foreign media reports, Beidou, a satellite positioning system independently developed by China, has begun to provide global services, highlighting the growth of China’s space power.

Exports to more than 90 countries and regions

According to a posting on the Hong Kong website of the South China Morning Post on December 28, Director of Satellite Management of China’s Satellite Management, Qi Chenqi, announced on the 27th that the basic Beidou No. 3 system was completed and will provide global services on the 27th.

The BeiDou system provides positioning services worldwide with a 5 meter positioning accuracy in the Asia-Pacific region and a positioning accuracy of 10 meters in other parts of the world.

Being one of the four largest satellite positioning systems in the world, the Beidou system stands shoulder to shoulder with American GPS, the Russian Glonas system and the European Galileo system.

“There is great confidence in maintaining good performance compared with other satellite navigation systems. In addition, we have many new services, ”he said.

He also said: “It can provide permanent and stable services to the countries of the world, including the countries and regions of the Belt and Road Traffic”.

According to Qi Chengqi, sales of core products, such as Beidou chips and modules, exceeded 70 million units, and Beidou high-precision products were exported to more than 90 countries and regions. Beidou served Russia, Thailand, Indonesia, Pakistan and Kuwait.

Qi Chengqi said: "Beidou is a global satellite navigation system that China independently creates and operates independently and is compatible with other satellite navigation systems in the world." He also said that the majority of smartphones sold in China support Beidou, and there are over 2 million vehicles in front of Beidou. ,

According to a report by the Russian Satellite News Agency on December 27, Qi Chen said at a press conference on the 27th that this year is a very unusual year in the history of China’s development in Beida: he completed the launch of 10 arrows and 19 stars a year, setting the world satellite navigation system and a new record for the same type of space launch in China.

Qi Chengqi said that in 2018, China’s high-density network Beidou formed a global service center and completed 10 arrows and 19 stars in one year, setting a new record for creating a global satellite navigation system and launching the same type in China. At the same time, a backup satellite was also launched, the orbit management strategy was improved, and service indicators were stable and increased.

Qi Chengqi said that by 2020, China will continue to launch 11 Beidou-3 satellites and 1 Beidou-2 satellite to further improve the efficiency of system maintenance. In 2035, a comprehensive location and navigation system will be built, based on Beidou, more ubiquitous, more integrated and more intelligent.

Emphasizing the growth of China’s cosmic power

On December 27, Bloomberg News reported that on May 27, China expanded its system business Beidou outside the Asia-Pacific region to become the dominant technology in the future.

According to the report, this system, like GPS, uses a series of satellites to provide users with accurate positioning with an error of about 10 meters. Most smartphone chips sold worldwide will be compatible with the Beidou system, which is the first navigation system with built-in communication capabilities, such as short messages.

Since the 1990s, China has independently developed satellite navigation and positioning systems in order to reduce its dependence on the global positioning system developed in the USA. Currently, Beidou’s research and development has entered a third phase, providing navigation and location services in different geographic areas to achieve global coverage by 2020.

The report also says that the Beidou system, which provides navigation and positioning services for the Chinese army and important infrastructure, is receiving more and more applications from map services to cars and smartphones. China launched the 42nd and 43rd satellites of the Beidou system in November last year, expanding its coverage area in parts of Europe and Africa.

Satellite navigation system Beidou is one of a series of ambitious plans implemented by the world's second largest economy to increase its competitiveness in the aerospace industry. Earlier this month, China launched a detector on the far side of the moon, a place in which no other country has risked. China is also developing a passenger airliner that can compete with Airbus and Boeing models, while private startups also rush to launch rockets to bring satellites into orbit at a low price to meet the demand for commercial space services.

According to the Japan Economic News website, published December 28, the Beidou system was launched as a military air defense system in 1994. The first satellite was launched in 2000 and opened to the public at the end of 2011. Since 2012, we have been providing positioning information for China and the Asia-Pacific region. It was originally planned to cover the whole world in 2020, but in fact it was completed ahead of schedule. China hopes to become a “space power” after the United States and Russia, and the Beida system will become an important part of this plan.

China’s goal is to make it a platform for the global high-tech industry in the future. It is expected that all parties will place higher demands on the ease of use and transparency of information processing of the Beidou system.

In addition, on December 27, the Taiwan Integrated Information Network reported that Beidou No. 3 basic system was completed and began providing global services on the 27th. This marks the expansion of the Beidou system from regional to global, and the Beidou system has officially entered a global era.

According to the report, with the rapid development of the Beidou system, its use in mainland China was very extensive: in Ningxia, farmers use it to plant agricultural equipment to provide unmanned driving, and in Inner Mongolia, shepherds can also send through remote areas to Beidou. Directive, remote control for water supply for livestock.

Market is expected to expand

Japanese Yomiuri Shimbun reported on December 28 that the Chinese government announced that Beidou, an independent satellite navigation system from China, began providing services to the world on the 27th. This year is the decisive year for the 40th anniversary of the reforms and openness of China, and it is also announced that the above news also aims to show its rapid progress in space exploration and positioning technology.

According to the report, the satellite navigation system, which provides services to the world, besides GPS, managed by the US Department of Defense with 31 satellites, is Russian Glonas and European Galileo, but GPS has an absolute advantage. ,

The Chinese leadership is in favor of implementing China’s remote sensing cooperation with Brazil, Russia, India, South Africa and other BRICS countries and intends to accelerate the popularization of the Beidu system, thereby expanding its international influence.

The report also says that countries such as Russia, Indonesia and Algeria are promoting the use of Beidou system products. After Beidou has launched its global service, it is expected that the market for Beidou will expand.

According to a December 27 report by the Taiwan United News Network, mainland China is increasingly seeking to promote its technical power in the rest of the world. Yang Changfeng, chief designer of the Beidou satellite navigation system, said that after completing the global network around 2020, the Beidou system will reach a world-class level and be even better than the international level.

According to the report, at the end of 2018, the Beidou system covered countries initiated by the “Belt and Road” to create the “Cosmic Silk Road”. Currently, Beida covers about 30 countries along the route, including Pakistan, Laos and Indonesia.
