"GNSS satellites carry extremely precise atomic clocks and constantly broadcast two key pieces of information: their exact position in orbit and the exact moment the signal was sent."
"Signals from global navigation satellite systems are quite vulnerable. They are exceptionally weak, meaning that any radio noise near their frequency, accidental or malicious, can interfere with reception."
"The challenge is getting leadership to both understand and act to reduce the risk associated with the fragility of GNSS technology."
Global navigation satellite systems (GNSS) include four satellite systems that provide precise location data for various applications, including navigation and military use. GNSS satellites broadcast their position and the time of signal transmission. Receivers on Earth use these signals to determine their location accurately. Despite their accuracy and integration into daily life, GNSS signals are vulnerable to interference. Experts emphasize the need for leadership to address the risks associated with these fragile systems, which can be affected by both accidental and malicious radio noise.
