Global Navigation Satellite Systems Engineering, Policy, and Design
Increasingly, professional and industrial users struggle to work around unexplained GNSS outages. Often, they don’t realize an interferer has popped up in their midst. Situational awareness is now a key component whenever GNSS is employed.

The Department of Homeland Security (DHS) Science and Technology Directorate has published the Positioning, Navigation, and Timing (PNT) Integrity Library and Epsilon Algorithm Suite to protect against GNSS spoofing. These resources advance the design of PNT systems and increase resilience of critical infrastructure to PNT disruptions.

The Department of Homeland Security is offering to test GPS equipment used in critical infrastructure to see how resilient it is against spoofing.
The effort is part of the GPS Testing for Critical Infrastructure or GET-CI program supported by DHS’s Science and Technology Directorate.

Previously, controlled reception pattern antennas (CRPAs) were only in the military domain, and highly classified. The need to counter increasing GNSS signal jamming and spoofing in the civil realm has brought CRPAs into limited use there as well. How to test for their efficacy in product design and development?
A free webinar on Wednesday, March 25 from 1:00 PM – 2:30 PM Eastern Daylight Savings Time addresses the topic “GNSS Vulnerability Testing and the Controlled Reception Pattern Antenna (CRPA).” This technically rich, educational event is sponsored by Spirent Communications and Inside GNSS.

Someone has updated 19th century American slang to resonate in the 21st century’s international commerce and shipping scene. A mysterious new electronic weapon has surfaced in China, spoofing GPS signals in a way that experts have never seen before.

Due to the proliferation of personal privacy devices and other jamming sources, it is imperative for safety-critical GNSS users such as airports and marine ports to be situationally aware of local GNSS interference. This article proposes and validates an enhanced method for geolocating GNSS interference sources so that jammers and spoofers can be found and disabled.

GNSS spoofing is more wide spread than previously believed and being used to not only misdirect satellite navigation users but to deny GNSS service altogether, according to a new report by the Center for Advanced Defense Studies, a non-profit that analyzes transnational security issues.

Solutions to toughen receivers (make them more resistant to jamming and spoofing), and to augment GPS signals with those from other sources, will require either replacement or modification of existing equipment.
