Spectracom, a main supplier to Testwall for timing and synchronisation equipment, is at the forefront of testing the vulnerabilities of mission critical GPS-based navigation systems and now offers its capability as a GNSS Vulnerability Test System.

The Challenge

Hardening GPS/GNSS-based navigation systems against the threat of spoofing.

The Solution

Easy control of “life sky” GPS and “spoofing” signals to understand the reaction of GPS-based navigation in various spoofing scenarios is the key to understand your vulnerability to spoofing attacks and to effectively implement countermeasures

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.
