LS Raw Files Fail to Process through DPOS

I've consistently been having issues processing a static file from one of my LS's, which happens to be the one I use as a base. I have a number of static files that won't process on DPOS online or through DPOS via Jfield on the rover LS. The message I get is: "Post-processing failed. Noisy GNSS data or small time span.".

No matter the site this is the error message I get. The unit is always placed in a good spot for a base and the static file certainly is not a small time span. I've logged static files with my rover LS and those process just fine if I upload to DPOS online, which makes me think there's an issue with my base.

Here's a link to a couple of different recent static files that won't process and it also contains the archived project (Base only):


I have also tried to process through OPUS to no avail.

Any assistance would be very much appreciated.

Give us new link to files. Existing link asks a permission.

I don't think Wes has this ability Alexey. He uses an LS LS base rovor system.

Phase data looks suspicious. This happens when internal antenna coaxial cable has bad connection to gnss board.
Could anything else cause it? Its not likely both of us have a bad connection. The project I sent the other day has a base session that won't process either. It returns the noisey gnss data warning. This was DPOS session Lawndale3_090533. Do I need to send you the project again or do you still have it?

Looks like J-field app send a command to GNSS board to reset tracking signals. Every 120 sec phase data accumulation restarts. No way to pp so broken phase data. CORS processing need at least 20 minutes uninterrupted phase data.

Alexey, it is set to 120 by default. Should we set it to 0 for the general group profile for the LS as a base. This should probably default to 0 when Use this LS as base is selected.

Got it. Thx. I'm going to have a crew reobserve L2 today after making this change.
