The System: First OCX receiver delivered to Air Force

November 3, 2016By
The first eight GPS III satellites are under contract and in production at Lockheed Martin’s GPS III Processing Facility outside of Denver.

Harris Corporation delivered the first of 34 modernized receivers to support the GPS Next-Generation Operational Control System (OCX). They will receive the signals sent by the current GPS satellite constellation plus the new signals sent by the next generation GPS III — 13 military and civilian signals in all. The receiver was shipped to the prime contractor, Raytheon Company, in... read more

Make it real: Developing a test framework for PNT systems and devices

OPENING GRAPHIC

Tests of the robustness of commercial GNSS devices against threats show that different receivers behave differently in the presence of the same threat vectors. A risk-assessment framework for PNT systems can gauge real-world threat vectors, then the most appropriate and cost-effective mitigation can be selected. Vulnerabilities of GNSS positioning, navigation and timing are a consequence of the signals’ very low... read more

Testing susceptibility to GPS spoofing

October 30, 2016By
The Vulnerability Test System.

Spoofing as it applies to GPS is an attempt to deceive a GPS receiver by broadcasting signals that the receiver will use instead of the live sky signals. Spoofing is different from jamming. Jamming is easier for a receiver to detect, and while it can disrupt the receiver, it cannot relocate it. Spoofing can be used as an attack on... read more

Innovation: Better GNSS navigation and spoofing detection with chip-scale atomic clocks

October 12, 2016By and

Getting there more safely
We discuss how chip-scale atomic clocks can help us navigate more safely by allowing a GNSS receiver to position itself more accurately even with only three satellites in view, and to protect itself by being able to detect a sophisticated spoofing attempt. read more
