The GNSSource-1000 is a low-cost, high performance GPS/GNSS primary reference source. It integrates a smart, low-noise disciplining OCXO and a GPS/GNSS receiver.
It integrates a GPS/GNSS disciplinable GXClock-500 function, using SmarTiming+R technology with an auto-adaptive loop time constant from 100 to 10,000 seconds, depending on the GPS/GNSS signal quality, at cutting-edge 1ns resolution.
The Safran GNSSource-1000 is specifically designed for cross-industry applications, where high stability and timekeeping features are required.
Applications:
• Synchronization
• Timing
• Reference/Test Source
• Time/ Frequency Source
