T3 Base battery died, re-started broadcasting fine, now there's no base file...

Yesterday the T3 battery died on me about 11/2 hrs into locating some wetland flags, (it didn't seem to be charging correctly, but that's a separate story). Fortunately we were able to get an extension cord and hook the base back up to the inverter in our van and continue working. I turned the base back on and connected with our LS+ assuming I would have to restart a new base point and then continue on. However, when I connected, everything was still running as the same base point and broadcasting corrections fine, and since we never moved anything and just plugged the charger into the unit I thought everything looked ok.

This morning when I tried to DPOS, it looks like I only have 11/2hr session from before the battery died. The second half of the day isn't matched with any base file, and I've checked the T3 for any extra base files, and haven't found anything. So now I have +/- 100 wetland flags that aren't able to be processed with the base. I tried "sync DPOS tasks" and re-downloading the base file, and that didn't solve it. Tried "recover base point" and "recover DPOS session". I don't think "post-process rover files" is what I really want to do here, because that sounds like everything will get re-processed without the base. Sending the project up to support, "K-10-135-2 STIPP SUB" LS+ 00998 T3 00121

You can try creating a base point for the 2nd set of points then use M-Local to shift them to the DPOS corrected point. You can't DPOS the rover vectors because there isn't a base file that matches the time. But, you could try post-process from the points menu resource button. I would export the points already dposd first. Then isolate the other points and then try post-process to get the ppk solution.

You don't have a base file for the 2nd set of points. You can recreate the base point then correct it with M-local. Highlight the 1st point in the 2nd set of points then tap the resource button and page over to recreate base point. Then highlight the created base point and hit the chart button. On the right tap the icon that looks like 2 planes. Pick the 1st base point as the known point. It should shift the 2nd set of points to the 1st base. Then you can try post process from the resource menu. I'm not certain how it will work but its worth a try if you need the ppk solutions. Just back up your points or project first.

What you describe is normal. Base/Rover setup starts the base file. The power off stopped recording. Power on continued the same base operation as when it was turned off (occupation coordinate and radio settings). Base file recording does not restart automatically. Only by pressing the record button or from base/rover setup command.

In what scenario would I want the base operation to continue without it recording? Seems counter-intuitive given that the base guards would cover the base getting knocked over/moved/stolen.

Aside from that, is there any way to fix this batch of points? I tried Adam's method and it didn't work. My thought is to just use the "recovered base" coordinate to shift the group of points once I get them into my drawing.

Yes. I'm sure it is. But I don't believe it would be appropriate for base/rover setup. I think it makes more sense as a static receiver.

I ran my T2 that way for a couple of years. If I remember correctly, base/rover setup would terminate the powerup file and start a new one. In APADDEN07's case, wouldn't that seeting have left him with a second base file he could later associate with the unconnected points?

I suppose it would. Using base/rover setup to start the base again would have done so as well, and also would have created the second base point needed for the file being recorded.
