Global navigation satellite systems (GNSS) play an integral role in our digital lives. Anyone who uses a smartphone for personal navigation is likely familiar with one of these systems, such as the Global Positioning System (GPS) in the U.S. or Galileo in Europe. However, the impact of these satellites extends far beyond navigation. In addition to providing precise positioning data, GNSS signals are a source of precise timing. A wide range of modern digital applications depend on GNSS timing to work properly, and interruption of these signals can have significant consequences, as highlighted in a recent New York Times article….
