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:
- Dual-frequency L1/L5 GNSS reception with microsecond-class 24-hour holdover, enabling precise, resilient timing in compromised conditions
- The M.2 B-key form factor drops into modern compute platforms, time appliance cards and embedded systems without custom mechanical design, all while drawing approximately half a watt
- Patented AI and ML algorithms, developed by the Jackson Labs team now part of VIAVI, predict and compensate for oscillator behavior across environmental conditions
- The Micro-Electro-Mechanical Systems (MEMS) oscillator delivers better thermal stability across the full military temperature range than traditional quartz Oven Controlled Crystal Oscillators (OCXOs), with sustained phase noise and Allan Deviation performance under vibration and shock
- Accepts an external 1PPS input, allowing it to be disciplined by M-Code GPS, alternative navigation sources, or other external references without hardware modification
- Multiple 1PPS and low-phase-noise 10MHz coaxial inputs and outputs for system integration flexibility, despite its miniature size.
