Because GPS and other GNSS are critical to the nation’s infrastructure, the U.S. Department of Homeland Security (DHS) is testing an augmentation system and developing new requirements to protect it, a DHS official told the U.S. Department of Transportations’s Civil GPS Service Interface Committee (CGSIC) meeting this week in Portland, Oregon.
NovAtel has released its GPS-173-GGG-N and GPS-713-GGGL-N explosive atmosphere- (ATEX)–qualified GNSS marine antennas with Inmarsat rejection filters.
The triple-frequency antennas are based on the company’s Pinwheel technology. Both antennas receive GPS L1, L2, and L5; GLONASS L1, L2, and L3 ; BeiDou B1 and B2; and Galileo E1 and E5a/b frequencies. The antennas can also receive satellite-based augmentation system (SBAS) signals and those from Quasi-Zenith Satellite System (QZSS) satellites.
Dana A. Goward is the President & Executive Director of the Resilient Navigation & Timing Foundation, a nonprofit, public benefit corporation that helps protect critical infrastructure by promoting resilient navigation and timing worldwide.
In 2013 he retired from the federal Senior Executive Service having served as the maritime navigation authority for the United States and Director, Marine Transportation Systems for the U.S. Coast Guard.

Dana Goward, President & Executive Director, Resilient Navigation & Timing FoundationThe U.S. Secretary of Defense has said “I hate GPS” and “I want to unplug the military from GPS.” Senior officials at the Department of Homeland Security (DHS) have called GPS “a single point of failure for critical infrastructure.”
GPS signals are used by virtually every technology. Their disruption for more than a brief period of time or over more than a small area could impact cell phone service, financial systems, computer networks, emergency radio systems, and every mode of transportation. It could be catastrophic for America.

Graphic Depicting NDGPS Coverage After Site ReductionsThe U.S. Coast Guard, the U.S. Army Corps of Engineers (USACE), and the Department of Transportation (DoT) released a Federal Register notice today (July 5, 2016) announcing a reduction of the Nationwide Differential Global Positioning System (NDGPS).
The planned reduction calls for the shutdown and decommissioning of 37 DGPS sites, leaving 46 operational sites available to users in coastal areas. Termination of the NDGPS broadcasts is scheduled to occur on August 5, 2016.
