I had a similar issue where I could no longer download UNAVCO files (and there are no other options for my area). After getting your same error I found a solution. Enter the HTML link to the correction file in the correction wizard dialog to a web browser. This took me to an Earth Scope website where I needed to make an account. Then I was able to download the file. Using the option to correct from a download file I was able to do the correction.
I am having a similar problem doing differential corrections. I have reinstalled my software and I have refreshed the providers list. Any other suggestions are welcome.
What bases have you tried to use and what messages do you get?
2 update list?
3 did you wait 24 hours after your last position?
4 select nearest CORS. Note it's 4letter code. Go to the CORS map. Enter the code. Select info. Select data availability. This expose the stations reporting health
5 if no data, Select next closest CORS.
Always Select t use ref position from base file. You want to go to heaven? Or datum he'll?
I have been told that the ssf file format is not compatible with RINEX files 3.x and higher and that some CORS bases, such as those in Florida, have switched to storing their RINEX files in this format. Eventually, all CORS stations will switch to this format. Once the format is switched, Pathfinder Office will no longer be capable of differentially correcting ssf data. Not sure if this may be the case with the CORS stations you are trying to use.
There are free utilities available that will convert RINEX V4 &/or V3 to V2 for use with PFO. You have to do it manually, but they work fine.
At the easy end Emlid Studio is simplest to use, current version will convert V3 to V2
At the other end, GFZRNX is much more powerful with many other features and will convert V4 or V3 to V2 but it's complicated and not for the feint hearted. You may also need another utility CRX2RNX to decompress Hatanaka observation files. I have a command file to automate the process for PFO that makes it simpler than EMLID Studio.
Hi. For clarity, it's not the SSF format that doesn't support RINEX 3, but rather GPS Pathfinder Office. SSF files can actually be post-processed using RINEX 3 files from Terra Office add-in for ArcMap.
