GPS spoofing is a technique used to deceive a Global Positioning System (GPS) receiver by sending false signals. This can cause the receiver to calculate an incorrect location, leading to potential disruptions in navigation and tracking systems. It is often used in various fields, including military operations and cybersecurity. The process involves broadcasting fake GPS signals that mimic legitimate ones, tricking devices into believing they are in a different location. This can have serious implications, such as affecting autonomous vehicles, drones, and even personal navigation apps, making it a concern for both safety and security.
