From maritime navigation to financial transactions, we are increasingly reliant on GPS. As a result, jamming and identity theft can wreak havoc and pose a threat to public safety. Fortunately, spectrum monitoring can detect and locate sources of jammers, and is able to prevent attacks through anti-jam and anti-spoofing techniques.

In London, a common use of signal jammer device is by taxi and HGV drivers evading maximum driving time regulations or attempting to prevent employers from complying with them. Elsewhere in the world, GPS jamming has been used for more sinister purposes. In 2016, South Korea was the target of a massive North Korean GPS jamming campaign, affecting the navigation of ships and aircraft.

Regardless of the target of GPS jammers, these devices do not discriminate, so additional collateral damage is often caused. Air traffic control (ATC), search and rescue operations, power grids, and mobile phone services are all susceptible to GPS jamming. The London Stock Exchange has suffered GPS outages on several occasions, affecting the timestamping of financial transactions. In 2007, the Navy conducted an exercise due to a loss of GPS communications in the Port of San Diego, which left residents unable to withdraw money from ATMs and doctors’ pagers stopped working – it took three days to identify the ship. As interference activity by civilian users becomes more frequent, we face similar interference as well as more deadly incidents, such as aircraft collisions in densely populated areas.

Spectrum monitoring, such as that implemented in London Countryside, is needed in smart cities to help detect and locate GPS jammers. Analyzing the spectrum to determine the duration of interference and the type of signal can also be used to indicate whether the interference is accidental or deliberate.

Those involved in unintentional interference are then notified and the malicious perpetrators prosecuted. This allows for quick resolution of the disruption and dangers caused by GPS jamming and acts as a preventative deterrent.

CRFS receivers have superior noise performance, allowing for detection and location over a larger area. Automation features minimize human intervention and trigger alerts when interference activity is detected. The video below explains how our advanced geolocation software detects interference activity, even in complex and crowded signal environments. Our GPS holdover modules also ensure precise timing synchronization between receivers, even if interference activity (or poor reception) means GPS signals are lost.

GPS jammers will have some impact on drones

According to Asian media reports, the drone was part of a 100-drone program that was cancelled after third-party intervention. The show coincided with the annual Hong Kong Food and Wine Festival. The planned seven-minute show included 100 rotorcraft with LED lights, marking the festival's 10th anniversary by forming the outline of a birthday cake and the number 10. The stuck drone disappeared during the show on Saturday, October 27. The show ends Thursday and Friday. "Upon initial inspection, the drone's GPS signal was jammed by a third-party GPS jammer, and the committee immediately reported the issue to the police," the organization said in a press release.

The potential for Russian electronic warfare in the 2nd Cavalry Regiment was announced by Col. Nicholas Kiotas, program manager for the region's positioning, navigation and timing services, at a C4ISRNET meeting on June 6 in Arlington, Virginia. "Now we can learn how to fix the equipment, because if we don't get jammed, we don't know what's going on," Kiotas said during the next commissioning of the system. "We took these systems, stressed them, and then tried to update them. So it's not a static system, we did it." The Army is using flexible acquisition tools to reach another agreement with three other vendors. Authorize the development of the second generation of MAPS. The design office requires suppliers to provide the best technology development, reflecting the low level of standardization in service capability development and their views on the use of GPS wifi jammers.
