Over the weekend, tests confirmed that all of these issues are related to a end of the year GLONASS day rollover bug in the GNSS receiver.  A power cycle seems to correct it until the next rollover in 2024. 

 If you're still seeing these issues then power cycle the device using a method appropriate to the device.  On the RackInjector in particular there is a power control button on the GNSS statusimulation screen.

Matt, 

I saw a similar issue today with Cambium PMP450i’s losing sync from our PacketFlux rack injectors. May not be useful information to you know considering there’s chatter about this already on social media. 

Thanks,
