Hello everyone,
My name is Dinar Haryadi, a final-year Geomatics Engineering student from ITS (Institut Teknologi Sepuluh Nopember), Indonesia. I am currently working on GNSS data processing using GAMIT/GLOBK for deformation analysis.
I encountered an issue when processing data from 2005–2009, where several stations show No Prefit and No Postfit coordinate solutions (e.g., BITI, BSIM, BTHL, PBLI, PSMK, PTLO, UMLH). The processing completes without crashing, but no coordinate solutions are generated for those sites.
Interestingly, when I process data from 2010–2024, everything runs normally and produces valid solutions.
I would like to ask:
What are the common causes of "No Prefit" and "No Postfit" in GAMIT, especially for older data?
Any guidance or suggestions would be greatly appreciated.
Thank you!
