I had 20 + hours static only needed a few hours but it was in a safe location so i just left till I had time to retrieve it.?ÿ When i submitted the .dat file it to OPUS i get?ÿ"1014 searching for "MARKER". OPUS will only process data taken from one............".?ÿ I used the trimlbe convert to rinex and i uploaded the file to OPUS and it processed the data.?ÿ ?ÿ

My question - does the Trimble Convert to RINEX clean up the data? I have no idea how to cut the data and process it in sections.?ÿ

Trimble converter just converts Trimble format files to RINEX, nothing more. You'd need to get familiar with a different set of tools.?ÿTEQC is what I use for parsing and cleaning up data.?ÿ There's a windows based GUI for it that makes it a bit more friendly to use. Works slick, but there is a learning curve.?ÿ?ÿIf you get stuck I can try and help you out. Good luck.

I wouldn't necessarily expect OPUS to properly read a DAT file at this point. I always use Convert to RINEX.

Try downloading and running the TEQC editor from this link:

I use teqc, but it functions the same as the trimble utility.?ÿ

?ÿ

Use a text editor (not MS word) to remove comment lines or other non-observation lines from anywhere past the header lines. For example, here are some lines near the end of a trimble .dat file....

?ÿ

I wish they would change OPUS to ignore this. I have files where there are comment lines at the very end of the file (nothing after them), and it of course rejects the file.?ÿ

?ÿ

I search for "COMMENT".?ÿ The lines above the highlighted area are the previous epoch data for two satellites, and the lines below are a new epoch. In this case I delete the highlighted lines and it runs fine in OPUS. There can be none, one, or multiple comment lines after the header lines.

It is probably a good idea to download the rinex specs and learn how the file is structured, it is simple ascii.?ÿ?ÿ

If you google that error text you will find several discussions of it.?ÿ This thread shows an example dealing with a stray MARKER entry.

John,

I doubt that the Comment line is the problem, it is the line with "YYYY MM DD Time" that indicate it is followed by data is the more probable problem. I would also expect OPUS should reject you for the L1 only data.

I split it into 3 hour segments and one came back as bad when it jumped crossed the UTC 24:00

Interesting.?ÿ They advertise that you are allowed ONE crossing of 2400 UTC in a file, and otherwise no upper length limits. Is there anything else unusual in that file?

This isn't the time of year for leap seconds, which do mess things up for a session around 2400.
