US Govt – ‘GPS Errors Felt Around the Globe, Across Industries’
Telecommunications systems around the world, broadcast systems in Europe, and Public Safety radios and aviation ground systems in the United States were among the technologies reported to the US government as being impacted by the GPS anomaly on the 25th and 26th of January.
Responding to an RNT Foundation request for information the US Coast Guard provided a summary of the fault reports received by its Navigation Center and by the Department of Homeland Security National Coordination Center. These are typically the reporting points for civilian concerns about GPS, while the Air Force serves as the point of contact for government agencies.
Separately, Jeff Dagle, Chief Engineer for Pacific Northwest National Labs, told the RNT Foundation that the SVN23 anomaly was also detected throughout the electric power generation and distribution industry. He did not give any specifics, but was preparing a paper on the incident to present at a conference next month. The electric power industry makes extensive use of GPS time and the 13.7 microsecond error impacted many of their receivers.
The only other information that has been made available about the impact of the outage on users has been a white paper by Chronos Technology. They also made available a graphic showing the GPS signal anomaly compared to the UK’e eLoran timing signal that, we understand, is being implemented as a critical infrastructure protection utility.
