When you open a map on your phone, you might think it is guided by the Global Positioning System (GPS) without giving it a second thought. However, today, most of the online maps in China uses the Beidou Navigation Satellite System(BDS,北斗卫星导航系统).
China started to build the BDS 30 years ago. Back in 1978, the US already started providing navigation services with its GPS. However, depending on a navigation system from another country is not safe.
In 2020, after over 20 years of hard work, Beidou completed its global network. The BDS became the fourth global navigation system after the GPS of the United States, Galileo of the European Union and GLONASS of Russia.
The BDS is the first navigation satellite system to provide a global short message communication service. It means you can text others in places without phone signal or internet. For example, in February 2023, a hiker got lost in heavy snow in Inner Mongolia. He sent a text message using the BDS-powered chip in his phone and got saved in time.
Besides, the Beidou system plays an important role in disaster prevention and response(灾害预防和响应). Rescuers(救援人员) can communicate through the BDS quickly and clearly.
No matter where you are in the world, the BDS can help guide your way. By 2023, it had provided service for over 120 countries. "By 2035, China will build a positioning, navigation and timing system with the BDS at its main aim to provide more smart services," Ran Chengqi, director of the China Satellite Navigation Office, said at a news meeting in 2018.
Many people like pandas very much because they are very cute. Most of them come from Sichuan, China. They have white hair and big eyes. Their ears, legs and shoulders are all black. Pandas are usually heavy, but they can climb trees like koalas. They like to eat a lot. It takes pandas a lot of time to eat food every day. When pandas are full, they like to sleep. They sleep for many hours every day. Because people cut down too many bamboo trees, pandas can´t find much food.
