题目内容

Many years ago,people depended on the sun,the moon and stars to find their way around. Later,the compass was introduced. And now,we have satnav(卫星导航)systems to guide us.

A satnav system uses groups of satellites to show the user's location. They send information to the receiver,such as a smart phone,to show us where we are.

The earliest built satnav system is the Global Positioning System(GPS),which belongs to the US. Then there is Russia's Global Navigation (导航) Satellite System(GLONASS),the European Union's Galileo and China's own satellite navigation system—BeiDou.

On October 14,2017,an ARJ21?700 plane,which was the first plane made in China,with the BeiDou navigation system,successfully completed a test flight. The results showed the performance of the system developed by China matches that of similar systems produced abroad,according to the Commercial Aircraft Corporation of China.

Since its introduction in 2000,the BeiDou navigation system has seen an increasing number of applications linked to everyday life,from shared bikes to farming. For example,smart locks with BeiDou chips make it easier to find a bike. Farmers can use BeiDou to help plow(犁)the soil and sow seeds. BeiDou's farming applications have spread to most parts of China.

With its many uses,the Beidou navigation system is even playing a big role in the Belt and Road Initiative(一带一路).“To date,the BeiDou system has covered most parts of the Asia-Pacific area”,said the main designer of the BeiDou system.

Today,there are more than 20 BeiDou satellites above the earth,and China plans to send even more this year to expand(扩展)the BeiDou network to better serve the Belt and Road Initiative. As BeiDou expands abroad,it will be increasingly popular in the logistics(物流)industry.
