WEST PALM BEACH, Fla.—Jericho Receivers, a wholly owned subsidiary of All 6G, this week launched its Software-Defined Atomic Clock (SDAC) that intelligently fuses multiple independent time references, including the ATSC 3.0 Broadcast platform to deliver atomic-clock-grade timing that remains accurate even when Global Navigation Satellite System (GNSS) signals are jammed, spoofed or unavailable.
“The Software-Defined Atomic Clock represents a major leap forward in timing technology,” said Dean Goodman, CEO of Jericho Receivers parent company All 6G. “When the primary timing source is lost, conventional systems enter holdover and begin to drift. There has long been a need for a true complement to satellite signals. Our software-defined approach fuses the best available sources — satellite, broadcast, terrestrial and network — into one resilient, atomic-clock-grade solution. This is precisely the kind of innovation All 6G was founded to deliver: bridging decades of broadcast expertise with the secure, resilient infrastructure required for 5G, 6G and beyond.”
“By leveraging the ATSC 3.0 Broadcast as a core terrestrial timing source, Jericho’s Software-Defined Atomic Clock directly supports the resilient national PNT infrastructure that Chairman [Brendan] Carr and the FCC have highlighted as essential,” Goodman added. “We are proud to deliver a made-in-America solution that strengthens timing security for critical networks while accelerating the broader adoption of ATSC 3.0 capabilities.”
Traditional systems that rely on a holdover mode during satellite outages in which the device keeps its own internal time, making time drift inevitable. Unlike those alternatives, the Jericho SDAC continuously cross-references GNSS, terrestrial ATSC 3.0/BPS signals and network-based precision time protocols. This multi-source architecture provides robust, real-time resilience for mission-critical applications.
“ATSC 3.0 was designed from the ground up to support advanced applications far beyond traditional video delivery, including precise time transfer and positioning through the Broadcast Positioning System,” said Madeleine Noland, president of ATSC. “We are thrilled to see Jericho Receivers’ software-defined atomic clock harness the power of the ATSC 3.0 standard as a critical terrestrial complement. This deployment underscores broadcasting’s vital role in building a more resilient national timing infrastructure.”
The Jericho SDAC intelligently combines:
- Global Navigation Satellite Systems (GNSS) for primary high-precision timing.
- ATSC 3.0 terrestrial broadcasts, including the Broadcast Positioning System (BPS), as a powerful GPS-independent complement.
- Network precision time references and protocols for seamless integration with modern IP infrastructure.
The architecture of the device ensures continuous, high-accuracy synchronization in challenging environments and eliminates the countdown to failure inherent in traditional holdover modes. Designed and manufactured entirely in the United States in accordance with All 6G’s strict no-Chinese-chip policy, the SDAC is well-suited for 5G/6G networks, data centers, power grids, financial systems, defense applications and other critical infrastructure that require assured positioning, navigation and timing (PNT).
The Jericho SDAC is now available for evaluation and deployment.
