What technologies in China are at the top of the world?

1, the largest single aperture spherical radio telescope (FAST) in the world.

Compared with the "Maximum Machine on the Ground" 100 meter aperture telescope of Eifelsberg, Germany, its sensitivity can be improved by about 10 times. Compared with the American Arecibo 300-meter-caliber radio telescope, which was rated as one of the top ten projects in the 20th century, the sensitivity of Sky Eye is 2.25 times.

2. Unmanned Aerial Vehicle

At present, for every 10 civilian unmanned aerial vehicles sold in the world, 7 are from China. China has achieved overtaking in corners and has sprung up everywhere.

3. Shenwei Taihu Light Supercomputer

Shenwei Taihu Light Supercomputer is not only nearly twice as fast as the second place "Tianhe No.2" (also from China), but also has three times higher efficiency.

4. Beidou Differential Instrument

The latest Beidou differential instrument has been successfully tested, and its accuracy has been improved from 10 m to 1 m. If it is combined with the ground-based augmentation system, its accuracy will reach centimeter level, and it has the function of short message, which exceeds the GPS in the United States in this respect.

5. China's high-speed railway

China has become the country with the longest operating mileage and the largest high-speed railway under construction in the world. China high-speed rail has become an outstanding representative of "Made in China" in the new era.
