The United States Naval Observatory (USNO), the global standard for precise timekeeping, recently purchased two DC-156-GPS Red LED atomic digital clocks to enhance accuracy and visibility at the entrance of their Washington, DC facility. These units were selected for their unmatched atomic clock accuracy combined with the exceptional visibility of 15.0″ high red LED digits, ensuring that every visitor can view the most precise time available.

The DC-156-GPS clock derives its time directly from GPS satellites, which are continuously synchronized with the NIST Master Clock, the definitive time reference in the United States. This ensures the time displayed is coordinated universal time (UTC) and meets the stringent requirements mandated by the Department of Defense. Managed by expert horologists, this timing standard provides unmatched reliability for critical applications.

The GPS receiver integrated with the DC-Digital clocks elevates their functionality to atomic accuracy. Once powered, these clocks never need manual setting, offering a true “set-and-forget” solution. Their robust design includes a heavy-duty IP-66 aluminum enclosure, making them waterproof and durable for long-term outdoor use.

Additional features of the DC-156-GPS include:

• Atomic, GPS-controlled 12- or 24-hour time format with hours, minutes, and seconds
• Extremely long viewing distance of up to 750 feet
• High-intensity LED digits with a wide viewing angle for maximum readability
• Simple operation with no setup required beyond applying power

Ideal for government facilities, industrial environments, or any location where precise, visible time is critical, the DC-156-GPS is a reliable, high-performance timekeeping solution that combines the authority of atomic accuracy with exceptional LED display technology.
