Surveillance drone to fight Gaokao cheating

Drones are taking off in a big way, and now they have one more role to play – as surveillance to prevent cheating in the national entrance exams, or Gaokao in Luoyang city, Henan province, Xinmin.cn reported on Wednesday.

Equipped with six propellers, the machine, known as a UAV (Unmanned Aerial Vehicle), has a flight radius of nearly one kilometer. It can also hover at 500 meters above the ground, the ideal height from which to perform a 360-degree scan.

As soon as suspicious signals from unauthorized electronics are detected, the drone will reveal irregularities on its control panel. It can also immediately and accurately determine the location of the electronic signals.

The drone was tested on May 29 in the city.
