I received the below error message from a rapid static upload. Ā Is there any way to obtain coordinates and elevation values? Ā I do not need tight tolerances, I just want to use this point as a verification. Ā Ā
Thank you

Ā 6009Ā Ā The OPUS-RS solution for the position of the rover has
Ā 6009Ā Ā failed to converge after 5 iterations. This could be due to

2005 - I don't think the precise orbits are available for a week or so. The rapid orbits are available at midnight Greenwich time.
6009 - Have you tried manually choosing which base stations to use? Also, are you just looking for a combined grid factor? I'll usually run RTK and then run a 20 minute static session on one of the points as a rough check and to get a CGF from OPUS. If you just need the CGF then: Ā Ā
If the prevous advice does not work, Try trimming 1-5 minutes off the beginning and end of your RINEX file.

the 2005 error is common - wait a few hours until after the end of the UTC day and try again - OPUS system hasn't updated yet.
on the 6009 error - can you look at the data yourself? Ā if so look for the data slice thats got the longest stretch of 6 or more sats and lowest RMS error. Ā Trim the data file down to a few minutes before and after the good data and then resend. Ā But be sure you've still got at least 20 minutes of data.
It never used to be a problem to clean sessions up like this
How long was your session? Ā Also, you need to wait at least 17 hours from end of session before sending to OPUS.
Try hacking off a minute or three from the front or back end of the observation.
