Signal authentication utilizing a dual frequency
software-based GNSS receiver for trusted positioning (SoftGNSStrusted)
Investigation of new algorithms for signal authentication using software-based GNSS receivers
Today, hundreds of millions of people worldwide use Global Navigation Satellite Systems (GNSS)
for determining user's position and time. The applications include nearly everything from
critical applications in transportation, information technology, health and emergency
services and defence to law enforcement. GNSS becomes an essential part in our society!
But, the more a resource becomes valuable to our civil infrastructure, criminal
or malicious agents seek to discover and exploit weaknesses in order to disrupt
legitimate users. The need for a secure and trustworthy GNSS position will become more
and more important. In a comprehensive study of GPS vulnerabilities the U.S. Department
of Transportation warned of these threats and a loss of quality and image of GNSS.
But, how can users be sure the information they receive is authentic? The signal
authentication, which will be necessary to assure a reliable determination of position
and time, was not an initial design consideration for civil use of GPS. In comparison
the upcoming European system Galileo will employ such features. But this service is
still a couple of years from operation. Further new methods for signal authentication
are just able to detect simple attacks, or need additional mostly expensive hardware.
The main goal of the proposed SoftGNSStrusted project is the investigation of new
algorithms for signal authentication using software-based GNSS receivers. Due to
higher computation power and flexibility of the receiver the developed methods will
allow the detection of intentional interferences like jamming, meaconing and especially
the complex spoofing.
