So far, more than 30 countries in the Middle East, Africa, and other regions have been using China's BeiDou satellite system, but BeiDou is also working to enter Japan, the United States, and Europe. So far, my country has 46 BeiDou navigation satellites. The larger the satellite group, the more accurate the positioning. In the past few years, my country's BeiDou has become as accurate as or has surpassed the satellite systems of developed economies.

Extended information:

1. Qualcomm, an American chip manufacturer (Qualcomm chips are the world's mainstream smart chips, and almost all mobile phones except Apple use Qualcomm chips) is compatible with the BeiDou system.

2. STMicroelectronics of Switzerland uses the BeiDou satellite navigation system in its automotive products. The head of the company's digital product department once said that we need semiconductor products that can locate positioning satellites across the country. Obviously, BeiDou is what they need.

Third, many Chinese technology companies are also using their own Beidou system. For example, Lenovo's new smartphone Z6 has a chip that receives signals from Beidou satellites, and its positioning accuracy can reach within one meter, while most smartphones can only be positioned accurately to 3 to 5 meters. Alibaba is also using the signals and data from more than 2,000 ground stations of the Beidou system to create a positioning service for self-driving cars that is accurate within the centimeter range.

The future is promising. The Beidou satellite navigation system will definitely become a world-class satellite system. I believe it will contribute to our social and economic development and the improvement of people's livelihood.
