Understanding the reaction of GPS-based navigation in various spoofing scenarios is the key to hardening the system against spoofing attacks.
The threats to GPS-based navigation systems are ever-increasing. The risk of intentional disruption of GPS signals is moving from simple jamming to a much higher-level of sophistication. Spoofing— an attempt to deceive by broadcasting false GPS signals— can be devastating, leading to loss of assets or, worse, lives. While testing the sensitivity to jamming is basic functionality of GPS simulators, measuring the effects of various spoofing scenarios requires a high degree of complexity.
