“It’s a glitch in the Matrix.”
Momentarily donning my tinfoil hat here, as I certainly don’t claim to know the
nitty gritty of how GPS timing works, but…
What if, since the GPS system is operated by the US Air Force, there was
something slipped into the GPS system relating to timing or

This email got stuck in the moderator queue for 6 days, I don't know why. I

But, by now this email has been overtaken by events. The more likely source
of the outage now appears to have been the GLONASS year rollover

Was there ever any additional information to come out about this? My Cambuim
lost sync starting at 21:00:23 UTC 12/31/2019 and didn’t come back until I
rebooted the unit…

I hate composing email on my phone. I always seems to mangle something.
Clarification: On the RackInjector, you can power cycle the GNSS receiver
using a button on the GNSS status page.

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

No issues to report from Miami, FL. Clocks are marked as stable and keeping
good time.

The following is from one ntpd instance in Chennai, India. We use Garmin
GPS 18x LVC receivers with our ntpd instances. ntpd interfaces directly
to the receiver using its NMEA driver and also receives a PPS signal
from the GPS receiver.
During last night, the ntpd process suddenly dropped its GPS
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.

Yes, lots of our key wireless network timing elements reported GPS
timing sync failure during the past two hours.
Appears to be resolving now, within the past few minutes.

Greetings,
This email is a response to

in which Forrest discussed GPS time sync issues today.
The galmon.eu project also monitors GPS, and one thing we found is that at
20:39:47 UTC today, which is near 2PM MST, GPS PRN 29
One of my hats is to design/manufacture/sell GPS third party timing
receivers for Cambium Radios.It seems like something happened around
2PM MST today which caused (at a minimum) certain Globaltop/Sierra Wireless
GPS modules to quit receiving signals from the GPS constellations.
Because these

On what hardware/firmware are you seeing this?
Nothing unusual in the Bay Area so far, in other words "All Quiet on the
