China flight systems jammed by pig farm’s African swine fever defences | South China Morning Post
Reports of criminal gangs using drones to spread infection led to installation of jamming device
Unauthorised equipment interfered with navigation systems of planes flying overhead
A Chinese pig farm’s attempt to ward off drones – said to be spreading African swine fever – jammed the navigation systems of a number of planes flying overhead.
The farm, in northeastern China, was ordered last month to turn in an unauthorised anti-drone device installed to prevent criminal gangs dropping items infected with the disease, according to online news portal Thepaper.cn.
The device came to light after a series of flights to and from Harbin airport complained about losing GPS signals while flying over Zhaozhou county in Heilongjiang in late October. In some cases, the ADS-B tracking technology – which determines an aircraft’s position via satellite navigation – failed.
