"How Do We Ensure GNSS Security Against Spoofing?"

The Global Navigation Satellite System (GNSS) refers to satellite navigation systems that provide positioning, navigation, and timing (PNT) services with global coverage. If the GNSS suffered a major outage for one day, it would cost the U.S. an estimated $1 billion in damage as this system is relied upon for automation, efficiency, and safety. All of the ways in which the GNSS can be exploited by attackers must be further explored in order to improve the security of this system against attacks such as GPS spoofing. GPS spoofing occurs when an attacker interferes with legitimate GPS signals using a radio transmitter that is near a target. In the context of military combat, an adversary could execute GPS spoofing attacks to manipulate GPS receivers, which could lead to the hijacking of autonomous vehicles and robotic devices. This article continues to discuss the concept of GPS/GNSS spoofing, incidents of GPS spoofing, the different types of spoofing, and how receivers can be protected against spoofing attacks.
