The impact of jammers on all areas of life

The impact of jammers on all areas of life

The vast majority of accidents involve GPS-based navigation systems that either lose the signal completely or (even more terrifying) misreport the role of the aircraft. Man Buesnel, a PNT security technology expert at Spirient Communications, a UK communications network provider, said there were about 50 cases with no immediate explanation.

Buenel said many of the reports he reviewed concerned military use of GPS jammer, but other incidents were deliberate or inexplicable.

Buesnel highlighted several other recent incidents outside the United States, such as a report by the Flight Offerings enterprise warning in October 2016 that the French GPS at Marseille Provence Airport was severely disrupted.

The report states, “GPS-based 31R / 31L and 13R / 13L programs are not currently available. “Before we talked about RPLL / Manila, HECA / Cairo (part of the Turkish FIR) and North Korea have the same problem. "

The FSB report also mentioned other incidents in Cairo, Turkey and North Korea. In May 2016, the Egyptian Civil Aviation Authority warned internal pilots against malicious attempts to use jammers with GPS signals near Cairo Airport.

Between 2014 and 2015, ASRS submitted several reports to NASA in which 121 aircraft carriers expressed concern about the loss of GPS signals near Mexico City Airport (MMMX). Excerpt from the pilot:
"When I carried out an RNA (GPS) navigation or an ILS Rwy 05R approach to MMMX under VMC conditions, I noticed that the FMC issued a warning when flying over the MAVEK intersection (SMO VOR):" GPS INVALID L, R. ““ This happened at a great distance. MAVEK struggle a mile away. When we entered the VMC, we continued to use a stable method to land smoothly. I strongly suspect that GPS interference has re-emerged near the Mateo VOR. "

UAVs are not immune to the threat of cell phone jammer. In December 2015, for example, the US Department of Homeland Security (DHS) first-rate publicly confirmed that its drones monitored at the US-Mexico border had suffered disappointments and GPS signal interference. According to their own statements, this was based on a Mexican drug cartel.

"We at Spirent have used interference detectors all over the world and the trend we are seeing seems to be to find more interference events," Buesnel told Avionics. "We found a lot of low-level glitches. This is not intended, but it will interfere with the GPS gadget."
