Which constellations are being used?
Was that a Jeopardy! Answer?????
Check them all only one of them does not work I think is the Chinese.
Select all of them
Then it depends on what your base is tracking

@johnymal We we??re staking out to a coordinate we??ve determined before. Turning on BeiDou moved the stake out from nearly flat to move 5 feet east. To be fair I didn??t have it on in the base at that time. Last night I was editing the style.
The other issue is it took it a long time to download a 2 hour file with 5 second epochs over Bluetooth, far longer than the old R10 base.
It's odd that it requires more time to download. I've noticed my TDC600 is much quicker than the older DC's I've used, are you using a new DC with the R12's or the same with both receivers.?ÿ
Having Beidou turned on should not affect the results by 5 feet. What correction source are you using? If VRS, definitely not. If RTX, you need to make sure the results are being transformed correctly to NAD83 (2011) or whatever datum you are using. If not using RTK/VRS/RTX, then you might be getting WAAS corrections, which are GPS only and referenced to ITRF with a 1 meter accuracy ?ñ. Or maybe you are just autonomous, in which case 1 to 2 m or more is possible.
I typically have GPS/GLONASS/Galileo/Beidou turned on all of the time at base and rover. I turn off the SBAS satellites so that I don't inadvertently get WAAS. If using VRS, it will just use whatever is available.?ÿ
Also, MUCH easier and faster to download over wifi. I connect my smartphone or laptop to the receiver over wifi and then download to my phone or laptop. I also have the ftp server running on the receiver.?ÿ?ÿ
Did you try the lemo to usb cable and a data stick??ÿ That should speed up that offload process.
Fairly new TSC5. Just updated to Android 11. Maybe that??s a mistake. The Android operating system sucks, TSC3 was far better than this. Damn thing is unresponsive, need a hammer for a stylus, just has a slightly aggravating feel. Once running in access it??s okay but getting files onto the stick at the end of the day usually a lot of swearing and cussing. Have to wait for the progress bar then some indeterminate length of time after that, how stupid.
We always run our own base. No VRS.
I??ve never had a problem downloading via Bluetooth. Will have to explore other options.
Bluetooth is a really tiny pipeline, iirc.?ÿ I tried downloading a simple text point file over it several years ago and I think it took 20 minutes.
The first generation Bluetooth handled 700 kbits (~ 70 kbytes/sec) and later ones are faster. There was some problem if a point file took 20 min.

It was the GNSS observation file. Other receivers I??ve had in the past weren??t that slow even though it??s Bluetooth. When I was downloading it out in the field I thought maybe it was a 1 second file because the style for an RTK base defaults to that but I had already changed it to 5 second.
I wound up putting the receiver and controller in the back seat and let it download while we drove down the mountain. I??ll check into Wi-Fi as an alternative.
Mostly I??m interested in which constellations people are using, it sounds like all.
Beidou are the best satellites up there. The B3 set broadcast 4 signals and have the least noise in their signals.?ÿ
Also you are recording way too much data at 5s logging for a 2 hour file. If you are using OPUS, it decimates the file to every 30 seconds, though Trimble RTX post processing will use 10s, intervals. Trimble has a white paper on static baselines with recommendations on logging intervals based on the total time that will be recorded. The longer the session, the less frequent data is stored. Shorter sessions is when you record in the 1 to 5 second range.?ÿ
When we added BeiDou to our receivers, via a firmware upgrade, it also needed a language change/upgrade in the DC, without which while the receivers would be ok tracking the BeiDou signals, there would be no transmission of the corrections.
