Beidou is China's first global navigation satellite system （全球卫星导航系统）. More than 120 countries and regions are using the Beidou system.

It started its full﹣scale （全面的） work on July 31，2020. With as many as 59 satellites，Beidou has "bright eyes". These satellites fly around the earth. They can "see" rivers，forests and mountains. They can "see" houses and schools on the earth. Of course，they can "see" you，too! From space，they can tell where you are on the ground，with a difference of no more than 10 meters.

Beidou can help people find the way，even when it's on the dark sea. It can look for mines （矿产） in deep mountains. It can give orders to driverless cars. Last summer，when Chinese people fought the flood （洪水） in the South，Beidou helped measure （测量） the rise and fall of the flood water.

What's more，when people are in danger and there is no mobile phone signal （信号） ，they can use Beidou to send a 1，200﹣word message to ask for help.

All in all，Beidou is there to keep us safe and make our life convenient.
