A groundbreaking initiative seeks to enhance global positioning systems through broadcast signals. The Broadcast Positioning System (BPS) leverages advanced television transmission standards to provide robust timing and location data. By integrating BPS into critical infrastructure, the system aims to complement existing satellite-based navigation technologies.
The foundation of BPS lies in the transition to ATSC 3.0, a next-generation broadcasting standard endorsed by international organizations. This standard has been under development since 2016, with over 100 transmitters currently operational across the United States. Countries such as Brazil, India, and South Korea are also exploring its adoption. A formal request to fully implement ATSC 3.0 by 2030 highlights the commitment to modernizing broadcast infrastructure while unlocking new capabilities for navigation and timing services.
BPS represents an innovative leap forward in positioning technology. Collaborative research conducted with the National Institute of Standards and Technology (NIST) demonstrates that BPS achieves timing accuracy comparable to dual-band GPS systems. Tests involving non-line-of-sight conditions reveal exceptional stability, with time deviations consistently below three nanoseconds. These findings underscore BPS's potential as a reliable alternative during disruptions to satellite-based systems. Furthermore, its independence from GNSS enhances resilience against intentional interference, ensuring uninterrupted service for essential applications.
The introduction of BPS promises transformative benefits for both public and private sectors. Utilizing existing high-power broadcast networks, the system offers nationwide coverage capable of penetrating indoor environments. Its passive receiver architecture supports unlimited users without requiring two-way connectivity, aligning closely with GPS functionality. Beyond enhancing critical infrastructure operations, BPS envisions hybrid applications combining traditional GNSS with terrestrial broadcasts. Together, these technologies could revolutionize transportation safety, emergency response coordination, and real-time kinematic measurements.
Innovation thrives when diverse communities collaborate toward shared goals. The seamless integration of BPS into modern telecommunications exemplifies this principle. By advancing ATSC 3.0 adoption and fostering partnerships across industries, we pave the way for a more secure and interconnected future. Embracing complementary technologies like BPS not only strengthens our reliance on precise timing but also fosters economic growth through novel business opportunities. As society continues to depend heavily on accurate positioning data, initiatives such as BPS demonstrate the power of leveraging existing resources to meet emerging challenges.
