“Whether it’s an everyday person using the navigation features in their car, a Wall Street broker making online trades, or a soldier in a combat zone, the Global Positioning System (GPS) and Global Navigation Satellite Systems (GNSS) play a role. In all scenarios above, depending on where a person, organization or group is in the world, GPS and GNSS can be compromised. Signal interference can occur due to a variety of reasons including gaps in cellular and satellite coverage, signal crowding and occluded environments, such as crowded cities or dense forests. Unfortunately, these gaps in service can cause a range of issues, from mere inconveniences to major lapses in critical communications infrastructures affecting safety and business continuity.” Link to article
