(ECNS) — China’s anti-cheating methods for national university entrance exams, known as Gaokao, have risen to a new level as Luoyang city of Henan province adopted a radio surveillance drone.
The UAV (Unmanned Aerial Vehicle) will
fight cheating during the upcoming exams
by monitoring and detecting radio waves
from high above the ground.
Equipped with six propellers, the machine
has a fly radius of nearly one kilometer. It
can also hover at 500 meters above ground,
dubbed “the ideal height” from where it
could perform a 360-degree scan, says Bai
Yujun, chief engineer at the drone
It can fly for half an hour per charge and
operates well in strong winds. The drone
can also “auto-land” when it encounters
partial mechanical difficulties or the battery
The drone was tested on May 29 in Luoyang
As soon as a suspicious signal is detected,
the drone will reveal irregularities on its
control penal. It can also immediately and
accurately determine the location of the
Luoyang’ radio management authority,
which is responsible for sourcing the drone,
has been ensuring radio security for exams.
In 2014, it uncovered 13 cheating signals
and performed nine interceptions. In four
cases, it confiscated three interphones, one
transmitter and three earphones, while
nine suspects were taken into custody.
