The Future of Precision Timing: A New System to Challenge GPS Dominance
The National Association of Broadcasters (NAB), Sinclair Broadcast Group, and UrsaNav have introduced an innovative system that offers an alternative to the widely used Global Positioning System (GPS) for precision timing. This initiative aims to reduce the reliance on GPS systems, especially in the event of an attack or compromise.
The Need for Alternative Timing Solutions
While GPS is a crucial tool for various industries worldwide, it remains vulnerable to potential attacks that could have severe economic consequences. The United States faces infrastructural challenges in ensuring reliable satellite-provided timing, lagging behind other nations in this aspect.
Industries such as agriculture, oil and gas, and telecommunications heavily depend on GPS for precise timing, which is essential for operational continuity in sectors like finance and communication.
The Economic Impact of GPS Failures
A study on the economic benefits of GPS revealed that the system generated approximately $1.4 trillion in economic benefits for the private sector in the US alone in 2017. Another study highlighted that a single day of GPS failure resulted in a $1.6 billion loss, totaling $58.2 billion within a month.
The Innovative Solution
The collaborative system from NAB, Sinclair, and UrsaNav offers an alternative timing capability that can supplement or serve as a backup to GPS. This system combines NAB’s Broadcast Positioning System (BPS) with eLoran, an advanced Position, Navigation, and Timing solution developed by the US Department of Defense and the UK’s Ministry of Defense.
- BPS utilizes ATSC 3.0, also known as NextGen TV, to enhance broadcasting TV signals.
Transitioning to ATSC 3.0 enables broadcasters to leverage BPS, offering improved emergency alert coverage, enhanced picture quality, and interactive features not available with traditional systems.
Industry Leaders’ Perspectives
Sam Matheny, NAB’s Executive Vice President of Technology and Chief Technology Officer, emphasized the resilience and terrestrial nature of the BPS and eLoran combination in providing an alternative to GPS.
Del Parks, Sinclair’s President of Technology, highlighted the trillion-dollar problem of GPS vulnerability in the US economy and showcased how BPS can leverage existing broadcasting infrastructure to address this issue efficiently.
Charles Schue, CEO of UrsaNav, advocated for adopting proven technologies like eLoran to safeguard the nation’s infrastructure and economy, citing the examples of other countries utilizing similar systems.
In conclusion, eLoran and BPS offer a reliable terrestrial solution for precision timing, especially in scenarios where GPS may not be available or trustworthy. This innovative approach provides a layered alternative for both metropolitan and remote users, ensuring continuity and reliability in timing applications.
