GPS-TEC analysis application (minor update to 2.9.1)

GPS-TEC analysis application (minor update to 2.9.1)
This application is a useful tool in deriving the GPS-TEC data from the rinex files.

Download program link --> GPS_Gopi_ver 2.9.1.zip

You can update to this version 2.9.1 temporarily. 
Only minor bugs fixed from version 2.9 
- program excludes the entire data at times when it assumes there are mixed satellite observables (from GPS, GLONASS). TEC from GLONASS is not processed, will be introduced later.

Yet, there are some receiver bias calculations problems to be fixed, occasionally like negative TEC values, bad TEC values, not good convergence in the diurnal trend etc. After fixing those bias problems,  I will post the updated program (version 3.0).

Please follow the instructions from the "GPS_TEC Readme.pdf"  document which is also inside the zip file.
Let me know if you have questions at my email address, please look it up in the above pdf document.

Thank you,
Gopi Seemala

  1. Hello Dr. Gopi, I have opted to use your
    analysis application for TEC derivation but every time I attempt
    to I always get the following error:

    open ftp://anonymous:anonymous@cddis.gsfc.nasa.gov
    Connecting to cddis.gsfc.nasa.gov ...
    Connection failed.
    Timeout detected.

    Connection failed.
    winscp> option transfer binary
    transfer binary
    winscp> cd pub/gps/data/daily
    No session.
    winscp> cd 2014/279/14n...."

    It is simply not connecting to the CDDIS server and
    can you maybe provide me with steps on how to configure
    the WinSCP to access the server because it keeps failing
    and I have to submit my work soon as it is a final year
    engineering project.

  2. Yet, by what method would they be able to filter through the garbage to get to the right GPS following framework? The most ideal route for them to do this is to instruct themselves on what GPS beacons are out there.https://www.engadget.com/2016/09/23/what-does-gps-actually-do-other-than-tracking/
