Signal Simulation Interference
Simulation Tool for GNSS Threat Analysis and
Mitigation Techniques
The SimSAFE software tool controls Radio Frequency
Constellation Simulator (RFCS) hardware in order to emulate
signal simulation attacks and test receiver mitigation
techniques. SimSAFE allows exibility in the attack scenario
denition and test of interference detection techniques. The
tool can be integrated into existing radio navigation testing
laboratories, in order to leverage existing hardware such as
signal simulators, interference generators and hardware GNSS
receivers.
The Spirent RFCS(s) are controlled by SimSAFE, and generate
all the desired signal simulation scenarios. SimSAFE also
monitors the output of attacked receivers and implements
detection algorithms. Post processing tools permit the
evaluation of spoong detection techniques based on
observed signal parameters. The tool allows the full scalability
and exibility for testing techniques that for example could
not be supported by existing hardware and software.
SimSAFE represents an innovative approach to the simulation
of attacks, the test of detection techniques and signal
authentication schemes, permitting maximum exibility,
minimum cost and risk, and the opportunity to leverage
existing Spirent RFCS equipment.
Features:
Accurate syncronization of RFCS time with GNSS time
Generates single channel spoofer or multiple channels
spoofer with desired dynamic
Synchronization of falsied signal code, power and doppler
• Support replay attack via realtime replica of space
navigation messages
• Supports analysis from different mass market and
professional receivers
Detection of false signals based on receiver observables
Architectures Supported
