TimeLink equipments are resilient by nature to GNSS vulnerability thanks to their internal architecture which
counts time using its internal oscillator in the first place and thus does not rely on the GNSS.
This internally generated time is compared to GNSS and any discrepancy is highlighted.
Then the oscillator is disciplined to the GNSS to get a long term stability.
