I am seeing a large number of bad OPUS solutions lately and was wondering if others are experiencing the same issue. This is happening in various locations in Louisiana and on different days with multiple receivers. I feel like I have crossed over into the Twilight Zone. This is crazy!
What do you mean by bad?
the obs used and integers solved along with peak to peak values are horrible. this has happened in 4 of the 5 projects done in December.
Are the CORS picked reasonable choices? Are the individual CORS results all equally bad? Were the setup locations all apparently good ones?
Maybe convert the same files to RINEX and manually choose CORS station possible different than the default OPUS chooses. Also look at those stations for available data in your time slots. I had a few projects I had to do that with as the CORS stations had gaps in data possibly from maintenance or an outage.
@hubermar here were a couple of hefty solar flares in December 2024. the one on the 29th affected my solutions. https://blogs.nasa.gov/solarcycle25/2024/12/#:~:text=Sun%20Releases%203%20Strong%20Solar,captured%20images%20of%20the%20events.
so from the questions I have received from you guys, I am assuming that you are not experiencing trouble with your GPS processing. That answers my question. It appears that we are alone in our recent problems with getting good solutions. I appreciate everyone's response, questions, and suggestions. That is what makes this forum worthwhile. Thank you all for your responses.

That latter flare gave us another great Aurora here DownUnder.
And I just happened to be bivouac-ing out that night
