I need help in preprocessing RINEX and SCINDA data files from IGS and GPS receiver. Initially I used the Gopi GPS TEC analysis software (versions 3.02 and 3.03), but it has stopped working (it can't download navg. files anymore). If anyone has an alternative or how to work with the current state of Gopi software I would really appreciate.
Hi,
You can manually download the navigation and DCB files and keep them in the program directory where your RINEX files exist. This is the best way to run the program offline.
For RINEX Nav files, http://garner.ucsd.edu/pub/nav
For DCBs, http://ftp.aiub.unibe.ch/CODE/
1) You can use https://cddis.nasa.gov/archive/gnss/data/daily to download nav and obs RINEX files.
2) I would suggest our TayAbsTEC software at http://www.gnss-lab.org/ . There are two steps 1 - "tec-suite" is to convert RINEX to ASCII files, 2 - "TayAbsTec" is to convert slant TECs to vertical TEC. The software does not need DCBs (it calculates DCBs itself). But you need to download obs and nav files yourself.
3) You can use SIMuRG project (https://simurg.space/) to have TEC, TEC variations or ROTI.
You can use GOPI TEC analysis version 2.9 to download the nav files and then use version 3.02 or 3.03 to process the RINEX data
