I am processing GNSS data using GAMIT/GLOBK 10.7 and encountered an issue with older datasets.

Processing setup:

- Year: 2009, DOY 001

- GAMIT/GLOBK: 10.7

- Command:

Stations that i use are located in **Indonesia** (BITI, BSIM, BTHL, PBLI, PSMK, PTLO, UMLH)

The processing completes successfully (no crash), but theres **no adjusted coordinate only** for the **2005-2009.** Even though I used the same step and command with all of my data (2005-2024)

I opened one of the DOY folder (001) and ran “gedit sh\*\_\*gamit\_001.summary” and it shows this :

```auto
List of sites without Prefit coordinate solutions:
BITI NoPrefit
BSIM NoPrefit
BTHL NoPrefit
PBLI NoPrefit
PSMK NoPrefit
PTLO NoPrefit
UMLH NoPrefit

List of sites without Postfit coordinate solutions:
BITI NoPostfit
BSIM NoPostfit
BTHL NoPostfit
PBLI NoPostfit
PSMK NoPostfit
PTLO NoPostfit
UMLH NoPostfit

```

I have the RINEX (.o), BRDC (.n), IGS (.sp3), and IONEX (.xxi (“xx” being the year’s backnumber)) files already available and make sure it was working properly.

I ran `sh_rx2apr` to generate/update apriori coordinates for the station (BITI, BSIM, BTHL, PBLI, PSMK, PTLO, UMLH) and it does not solved the problem

I opened the DOY folder and theres no “GAMIT.fatal” file, meaning that theres no fatal errors when im running the command all around

I dont understand why only the 2005-2009 that has this problem, meanwhile the 2010-2024 working perfectly fine.

Does anyone has experience dealing with this type of problem? or what should i do?

I call your attention that there is no direct GMT question in your post. Specially, there **no reproducible example**. If you don’t provide one I’ll remove this as, as far as I can see, this is a GAMIT question and not a GMT one.
