Hey Guys
Around 11:30 NZ local time we effectively lost survey grade GPS for the entire country 🙁
GLONASS was working fine, but the US sats were all FU
Unfortunately our US based software uses US sats for perference, so for us, basically nothing worked.
I see Shawn's post below.
Does anyone know if we are back in action yet?
Thats very interesting because by all other reports it was GLONASS that had a dodgy ephemeris and was useless and GPS was fine all the time.
All of our machines stopped working around sometime around 6 pm cst. I was out there messing with them until around 10 and they weren't back yet. I was guessing at the time that it was the us sv's.
Wondered why my base station had gone offline during the night...
got it back working at 07:30 GMT
I just talked to the crew at 8:30a.m. central time and our system is working fine including the Glonass.
Ours is up
GPS never goes down. Never.
It would be big news in all major newspapers and tv news programs if it did.
Your receiver is probably being affected by the GLONASS problems.

Sorry, but that was NOT our experience.
Our R8 and R10 receivers just would not fix.
The problem was evident right through New Zealand - not just us, and not just Trimble shops

I was surprised it hasn't hit the news - but it does seem only survey grade users were affected. Consumer grade still seemed to be working - losing that would create more noise.
And I do wonder how many machine control sites will have re-work to do...
Downloading yesterdays R8 static work and a number of yesterday's observation files are missing, just not there in the receiver. Checked the times and appears to be in the same time frame. Weird.
It didn't hit the news because GPS operated perfectly fine everywhere in the world yesterday.
It's a problem with your receivers (and others), probably due to the published GLONASS problems.
I'm not trying to be arrogant, just pragmatic. GPS is unbelievably reliable and is relied on by entities in applications way beyond what we can imagine.If it hiccups, it hiccups everywhere (not just above New Zealand)and everyone would know it due to the widespread number of applications it's used for.

We experienced some odd GPS issues yesterday with our R8 GNSS receivers and TDL radio. Lost radio, went back to radio which was off. Restarted everything, radio started up just fine and it said it was broadcasting yet our R8 could not receive the signal at all. 90 minutes later it still wasn't working...and the day was over. Today its working just fine, odd.
I'm pretty sure your radio issue wasn't a radio issue. I can't explain the radio powering down, but I can say that last night at midnight, I tested our receivers during the Glonass hiccup. With Glonass turned on at the base, the base radio appeared to be sending corrections but the rovers received nothing (as if the radios weren't even on the same frequency). Turning Glonass off at the base (and changing nothing else) I was able to get corrections at my two rover receivers. My guess is that the data from the Glonass satellites was so corrupt that the base corrections were not even intelligible to the rover. It had all of the appearances of a radio malfunction (the base was transmitting and the rover was not receiving), however, just dropping Glonass at the base made everything work properly. Had I been in the field, I'd have guessed radio malfunction too.
