You need a recent Matlab installation (R2014b or later). VieVS is tested on Windows and Linux. Download or clone the VLBI repository and(!) the COMMON repository and put them to the same directory. If your main directory is called 'VieVS' for example, your folder structure should look like this:
/VieVS/COMMON/
/VieVS/VLBI/
Please be aware that this repository contains more or less only the program code. The data files necessary for processing have to be downloaded from external sources.
- NGS can be downloaded for example from ftp://cddis.nasa.gov/vlbi/ivsdata/ngs/ and have to be stored in year folders (NGS-files have to be uncompressed):
/VLBI/DATA/NGS/yyyy/ - vgosDB can be downloaded from https://ivscc.gsfc.nasa.gov/hfeop_wg/vgosDB_IVS/ and have to be stored in year folders as you download them (compressed tar files, *.tgz or *.tar.gz):
/VLBI/DATA/vgosDB/yyyy/ - Master files are needed for the automatic generation of a process list, they can be downloaded from ftp://cddis.gsfc.nasa.gov/pub/vlbi/ivscontrol/ as yearly *.txt files and have to be stored in :
/VLBI/DATA/MASTER
- EOP C04 can be downloaded from ftp://ftp.iers.org/products/eop/long-term/ . Take for example "eopc04_14_IAU2000.62-now" and store it as
C04_14_1962_now.txtin/VLBI/EOP/. - EOP finals can be downloaded from ftp://ftp.iers.org/products/eop/rapid/standard/ . Take for example "finals2000A.all" and store it as
finals_all_IAU2000.txtin/VLBI/EOP/.
- Mapping functions: VMF1 and VMF3 can be retrieved from http://vmf.geo.tuwien.ac.at/trop_products/VLBI/ . Choose the yearly files and store them in the respective folder (VMF1 or VMF3) in
/VLBI/TRP/. - Gradients are available from http://vmf.geo.tuwien.ac.at/trop_products/VLBI/GRAD/ . Choose the yearly files and store them in the respective folder in
/VLBI/TRP/GRAD. - Ray-traced delays are available from http://vmf.geo.tuwien.ac.at/trop_products/VLBI/RAYTR/RADIATE/. The *.radiate files have to be stored in year folders in
/VLBI/TRP/RAYTRACING_DATA/yyyy/.
Start Matlab, go to VLBI/WORK and type vievs in the command window to start the VieVS graphical user interface.
