GNSS interference has become a persistent operational concern rather than an edge case. Dual-frequency L1/L5 reception is increasingly being specified in defense and critical infrastructure procurements as a baseline requirement. Demand for compact, low-power precision timing continues to grow across multiple markets, especially as warfighters and unmanned platforms must limit payload to stay agile, and customers who designed in chip-scale atomic clocks (CSACs) face cost and lead-time pressure.
The µPNT GDO-1000 addresses these challenges through a unique combination of capabilities:
- The module pairs dual-frequency L1/L5 GNSS reception with microsecond-class 24-hour holdover
- The M.2 B-key form factor allows the module to drop into modern compute platforms, time appliance cards and embedded systems without custom mechanical design, all while drawing less than half a watt
- The Micro-Electro-Mechanical Systems (MEMS) oscillator has lower g sensitivity than a traditional quartz crystal Oven-Controlled Crystal Oscillator (OCXO), making it better suited to withstand significant vibration and shock
- The module accepts an external 1PPS disciplined input, allowing it to be slaved to M-Code GPS, alternative navigation sources, or other external references without hardware modification
- The disciplining intelligence behind the module reflects years of focused engineering by the same team that built Jackson Labs Technologies' reputation in precision timing, now continuing that work as part of VIAVI.
