FAQ
- What happens if GNSS lock is lost?
Auto-calibration applies stored compensation coefficients, maintaining OCXO stability (5 ppb/day typical) until lock is restored. - Which satellite constellations are supported?
The system tracks GPS, GLONASS, SBAS, and QZSS to minimize lock time and enhance reliability. - How does the dual-time base option work?
It adds a second GNSS receiver and gapless counter that continually verifies the 10 MHz reference and warns of tolerance drift.
