JTG is a VOR combined with DME transmitter used in aviation navigation near Zhouzheng, China and about 40 km north east of Chendu City, Sichuan province, China.

VOR, short for VHF Omni-directional Radio Range, is a type of radio navigation system for aircraft. VORs broadcast a VHF radio composite signal including the station's morse code identifier and data that allows the airborne receiving equipment to derive a magnetic bearing from the station to the aircraft.

Distance Measuring Equipment (DME) is a transponder-based radio navigation technology that measures distance by timing the propagation delay of VHF or UHF radio signals.
