At midnight UTC on January 25 there was a GPS anomaly seen by many receivers. Several of these receivers showed a time jump of varying magnitude (typically 14 microseconds). TimeKeeper GrandMasters did not exhibit this behavior and our monitoring units in the US (Texas and New Mexico) and Europe (Paris) did not show this behavior.
No customers using our receivers have reported errors in time or seen the issue that some units showed either.
We are still monitoring the situation and will update you when we have more information and official information from NAVCEN. This issue appears to correspond to the decommissioning of a GPS satellite and may be related: navcen
