GPS navigation signal is an important technical guarantee for aircraft flight safety. The crew of a civil airliner who landed at Liuzhou Airport not long ago reported that the aircraft was about 8 kilometers above the runway when it was descending and preparing to land. GPS signals began to be interfered by radio until the distance About 4 kilometers above the runway, the GPS interference signal disappeared, and the length of time that passenger aircraft was interfered on different flights was different. The shortest time for passenger aircraft GPS to be interfered was 60 seconds, and the longest time was 125 seconds.
The reporter learned from Liuzhou Radio Monitoring Center that recently, the center used technical means to jointly enforce the law with relevant departments. This case of civil aviation passenger aircraft GPS interference was seized and handled, eliminating potential safety hazards.
It is understood that on June 28, Liuzhou Airport submitted a radio interference complaint form to the Liuzhou Radio Monitoring Center: Recently, when a civil aviation aircraft was preparing to land on the runway of Liuzhou Airport, the GPS signal suffered severe radio interference, resulting in loss of GPS signal and interference. The most serious passenger plane lost GPS signal for up to two minutes. The GPS signal is affected by the GPS Jammers and the aircraft approach and landing, gps blockers do they work, some flight crews adopt the termination of the RNP approach procedure, and use visual control of the aircraft to land, which seriously affects the approach and landing of the civil aviation aircraft and improves flight safety Brings safety risks.
After receiving the complaint, the Liuzhou Radio Monitoring Center dispatched monitoring personnel and dispatched mobile monitoring vehicles to carry out carpet radio monitoring and interference investigations on the area under the GPS interference route. It was found that the source of the interference was set at the Liuzhou Power Supply Bureau on Ruilong Road. A GPS jammer in a second-hand car warehouse next to the Fort Substation. After questioning, the owner of the car warehouse confessed that the jammer was purchased from Taobao and it was used to shield the GPS signals of cars in the warehouse to prevent vehicle positioning information from being discovered.
On July 21, Liuzhou Radio Monitoring Center, Municipal Public Security Bureau Airport Branch, and Liuzhou Airport launched a joint operation to investigate and deal with the illegally installed GPS signal jammer in the warehouse. The Liuzhou Radio Monitoring Center and the staff of the Public Security Bureau conducted a preliminary inquiry and investigation of the warehouse owner. After that, the public security police seized the GPS signal jammer and brought the warehouse owner back to the Public Security Bureau for further investigation.
At this point, the GPS signals of all civil aviation aircraft that landed at Liuzhou Airport have returned to normal, and the radio signals that interfered with the GPS positioning of the civil aviation aircraft have completely disappeared. GPS blockers do they work and hidden dangers affecting aviation flight safety have been eliminated.
Flight safety is no small matter. Although this case is resolved, the citizens still need to popularize some laws and regulations related to radio. According to the relevant provisions of the "Regulations on Radio Management of the People's Republic of China", if the use of radio transmitting equipment or non-radio equipment that radiates radio waves interferes with the normal operation of radio services, the radio management agency shall order corrections. If corrections are refused, the equipment that causes harmful interference shall be confiscated A fine of not less than 50,000 yuan but not more than 200,000 yuan; for ships, aircrafts, spacecrafts, railway locomotives dedicated radio navigation, distress assistance, and safety communications that cause harmful interference to personal safety radio frequencies, a fine of more than 200,000 yuan A fine of less than 500,000 yuan; if a crime is constituted, criminal responsibility will be investigated according to law. Even if there is a valid reason, any unit or individual using GPS signal jammer must be approved in advance.
