GNSS denial of service and the preparation for tomorrow's threats

As GNSS receivers become common in our daily lives and our reliance on them grows stronger, GNSS attacks also are becoming more common and sophisticated than ever. These attacks can range from accidental interruption to intentional denial of service to advanced spoofing equipment designed to deceive the GNSS receiver and make it think it is located elsewhere. Without proper protection, these real-life threats can cause, for example, temporal closure of airports and loss of autonomous vehicles. Today's solutions for defending against such attacks are limited, expensive or require significant processing power that cannot be implemented in energy-critical applications. This work suggests a low cost, efficient and simple method to cope with the threats and demonstrates its operation in a real-life scenario.
