What is the positioning accuracy of Beidou Global Satellite Navigation System? How many words can be sent by Beidou short message communication at a time? How many of our mobile phones are compatible with Beidou system? Where are the Beidou apps around us? "Number" said Beidou, let's take a look at "how" does Beidou relate to our lives?
Beidou positioning
Since the joint prevention and control of the New Coronary Pneumonia epidemic has been carried out, under the strong leadership and careful arrangements of the municipal party committee and municipal government and the head office and the party committee of the sub-branch, the employees of the whole bank have worked together to overcome the difficulties. While ensuring that the prevention and control of the epidemic is foolproof, Comprehensively promote the sustained and steady development of various businesses. In particular, the majority of grass-roots front-line employees can obey the command and take care of the overall situation.
Beidou time
Timing is also a basic service of satellite navigation systems. Globally, the timing accuracy of the Beidou system is better than 20 nanoseconds; in the Asia-Pacific region, the timing accuracy is better than 10 nanoseconds. One nanosecond is equal to one billionth of a second.
Beidou short message communication
Short message communication is the exclusive secret of Beidou. If there is no mobile phone signal at sea, or communication is blocked during a disaster, you can send a short message through the Beidou terminal. Short message communication service in China and surrounding areas can send 1000 Chinese characters at a time. Global short message communication service, can send 40 Chinese characters at a time. At present, more than 70,000 fishing vessels and law enforcement vessels in my country have installed Beidou terminals. Fishing vessels can be rescued by short messages in distress. At present, more than 10,000 people have been rescued.
Beidou chip
After years of development of domestic Beidou chips, the price of a single chip has dropped from hundreds of yuan to less than 6 yuan. As of the end of 2019, shipments of domestic Beidou navigation chip modules have exceeded 100 million, and quarterly shipments exceeded 10 million. As of the end of 2019, the total sales of domestic satellite navigation and positioning terminal products exceeded 460 million units. At present, including smartphones, the total social ownership of terminal products using Beidou compatible chips has exceeded 700 million units (sets).
Beidou mobile application
Smart phones have become one of the most important application areas of satellite navigation systems. At present, mainstream chip manufacturers both at home and abroad have launched integrated conduction chips compatible with Beidou. As of the end of 2019, of the 460 million satellite navigation and positioning terminal products sold in China, the sales volume of smartphones with satellite navigation and positioning functions reached 372 million. As of the third quarter of 2019, there are more than 400 mobile phones that have applied for access to the network in the Chinese market with positioning functions, including nearly 300 models that support Beidou positioning. In the first quarter of 2020, more than 75% of smartphones applying for Internet access in the Chinese market support Beidou positioning.
Beidou Transportation Application
The Beidou application is moving towards a new stage of "standardized" development in many fields such as transportation. In terms of transportation, there are currently more than 6.5 million operating vehicles, 40,000 postal and courier vehicles, about 80,000 buses in 36 central cities, more than 3,200 inland navigation facilities, and more than 2,900 maritime navigation facilities already using the Beidou system .
Beidou participates in smart agriculture
The food on our table is also related to Beidou. At present, there are more than 20,000 sets (sets) of agricultural machinery automatic driving systems based on Beidou. The Internet of Things platform based on Beidou's agricultural machinery operation supervision platform provides services for more than 100,000 sets (sets) of agricultural machinery equipment.
Beidou high precision detection
The Beidou high-precision gas leak detection vehicle has been put into use in Beijing. The Beidou high-precision gas leak detection system can quickly and sensitively detect the gas leak point within 150 meters and accurately locate it.
Beidou Industry
At present, the number of enterprises and institutions in the field of satellite navigation and location services in my country has remained at about 14,000, with more than 500,000 employees. As of the end of 2019, the total number of related listed companies in the industry (including the New Third Board) was 46. Beidou high-precision and Beidou assisted rapid positioning users have exceeded 500 million.
Beidou output value
The 2020 White Paper on the Development of China's Satellite Navigation and Location Services Industry shows that in 2019, the overall output value of my country's satellite navigation and location services industry was nearly 345 billion yuan, an increase of 14.4% from 2018, and has maintained double-digit growth for 9 consecutive years.
