China has completed its BeiDou Navigation Satellite System (北斗卫星导航系统), or BDS. It becomes a new system in the world with a global navigation network (全球导航网络). The other three systems are GPS of the US, GLONASS of Russia and Galileo of the European Union.

As the name suggests, the global navigation satellite system provides navigation and location services 24 hours a day. As we know, building a good satellite system costs a lot. Besides, the other systems have been set up. Why does China have a new one if there is nothing special?

The other three systems have 24 satellites. China’s BDS has six more satellites. What’s special about these six satellites is that they have a relatively fixed area of activity. This can improve BDS’ accuracy (精准度) in China and the Asia-Pacific region to 5 meters, compared with a 10-meter accuracy in other areas.

BDS has another advantage-the short message service. It allows users to have a two-way communication. In areas that are not covered by communication signals (信号), users can send short messages. Even in uninhabited areas, such as deserts, forests, mountainous and polar areas, BDS can also make the short message service available. With this service, users who are in danger can tell the rescue team (救援队) their location and condition.

As the most populous country, it’s important for China to have its own global navigation satellite system to meet the needs of the country’s development. In fact, BDS is also good business. According to the official report, China’s satellite industry has kept a 20% yearly growth since 2012. And BDS contributes about 80% of it. In addition, BDS has also created countless high-paying jobs. And with continuous improvement, it will have much more to offer in the future.
