Presentations and Articles: Testing GNSS Receivers to Harden Against Spoofing Attacks Spoofing is an attempt to deceive the GNSS/GPS receiver by broadcasting signals that the receiver will use instead of the live sky signals. This article describes a test system for spoofing allows testing the three major factors to consider in a spoofing attack, time synchronization to the signals to be spoofed, power level of the spoofing signal compared to the live sky signals, and accuracy of the position obtained by the spoofing signal to that of the actual position of the device being spoofed. Using a spoofing test system will allow a user to better understand the receiver and harden the system against spoofing attacks. pdf - 673 KB

Presentations and Articles: GPS/GNSS Spoof Testing By Simulation

Hardening GPS/GNSS receivers against spoofing and jamming is crucial as threats are new, real and increasing. Testing with a GPS/GNSS simulator is a very effective tool for designing and evaluating countermeasures for mission-critical applications for positioning, navigation and timing. This presentation describes the application for testing spoofing.

Case Studies: GPS Timing Integration for Small Form Factor PDRS

Spectracom’s TSync bus-level timing platform was integrated into a new small, rugged, Passive Detection and Reporting System (PDRS) to receive GPS, discipline an onboard rugged ovenized crystal oscillator and generate high precision time and frequency signals for system synchronization. It also delivers GPS coordinates for the system.

The development of the system greatly benefited from Spectracom's customization-to-COTS approach by adapting the platform into a standard VPX-based card without the need for non-recurring engineering charges. It offered the necessary ruggedization, small size, and low weight and power consumption to meet the goals of system portability, and is available with secure SAASM GPS.
