When you want to go somewhere, you can easily find your way by using a map app on your smart phone. Your smart phone “knows” where you are and can tell you where to go.
This is possible with the help of satellite navigation (satnav) systems (SNS). A sutnav system uses groups of satellites to find out where people are. It sends information to a receiver, such as a smart phone. The more satellites a system has, the more accurate it will be.
On June 23, 2020, the last satellite of China’s Beidou Navigation Satellite System was sent into space. Beidou, China’s own satnav system, was finally completed. It is one of the four global navigation systems, along with US’GPS, Russia’s GLONASS and the European Union’s Galileo.
On July 31, Beidou started providing full-scale global services. More than 120 countries and areas are now using Beidou services.
Since 2000, China has sent up 59 Beidou satellites! Beidon can be used in areas that include farming, public services and business. It has a positioning accuracy of under 10 metres. This summer, people along the Yangtze River used Beidou-based device to monitor floodwaters in real-time with an accuracy of just a few centimeters.
Beidou also has a special messaging ability. It allows people to send text messages up to 1,200 Chinese characters in length when mobile phone services are broken.

Have you ever dreamed about sending a letter to yourself or your friends in the future? While express mail (快递) is a fast way to send your letters, there is another type of mail appearing in China as a new business—future mail.
“The letter should be sent next Mother’s Day and not a day earlier!” Lin Xiaofan, a college student in Shanghai, tells one of the companies offering the service.
Lin Xiaofan wrote the letter to her mother nearly a year earlier to express her love to her mother for next Mother’s Day.
“Offering this service makes people slow down and lets them understand the meaning of ‘time’ in another way,” said Zheng Zhimin, manager at a “future mail” company. Zheng thinks “future mail” letters help remind us of care, friendship and love.
While “future mail” is becoming more and more popular, some people are wondering what will happen if the postal address changes or if the company goes broken before the letters arrive.
Zheng said customers are glad to sign a contract (签订合同) to make sure that they can be compensated if their letters are lost or damaged.
Most of the customers are college students and young white-collar (白领) workers. Psychologists (心理学家) said that young Chinese might have a new way to express their feelings through this service. Most people put their hopes and wishes in the letter so that they can experience the connection (联系) between the past and the present when they receive the letter.
