#GPS2TEC

This prohram is for calculate total electron content(TEC) from gps signal

#Directory and file discription

bin/ : some binary files (different version of crx2rnx)

gps2tec_modules/ : subroutines

gps2tec.inp : input file

gps2tec.py : main program

marker.crd : gps station xyz coordinate list

#Usage

python gps2tec.py [input file]

#Input file discription

case_type :

local  -- Calculate GPSTEC from o file in current directory.

IGS    -- Download GPS source file from IGS(International GNSS Service) and calculate TEC.
                    
IGSRT  -- Download real-time GPS source file from IGS and calculate TEC.

year :

 Year of run time.

save_pwd :

Specifies the save directory and it will create directory by different days(e.g. /path_to_save/YYYY/DDD) in this 

directory. If set empty, it will create directory at current directory.

st_doy :

Start DOY of run time. (for case_type IGS and local)

ed_doy :

End DOY of run time. (for case_type IGS and local)

download_list_fn :

Specifies the GPS station list filename for downloading from IGS. The GPS station list file should have different 

station name in different line, and have station name in first 4 char in each line. If set empty, it will 

download al GPS data from IGS. (for case_type IGS)

doy :

DOY of run time. (for case_type IGSRT)

hh :

Hour of run time. (for case_type IGSRT)

mm :

Minute of run time. (for case_type IGSRT)

gim_days_before :

Download GIM data the days before the run time. (for case_type IGSRT)

time_delay_minute :

This number should depend on [mm]. Because real-time GPS data is release at 15, 30, 45 minute each hour, 

so [Minute of run time] - [time_delay_minute] should be 15, 30 or 45. (for case_type IGSRT)

stnbias_method : Station bias method.

GIM      -- Calculate station bias by the value and the time of GIM minimum TEC.  

FITTING  -- Calculate station bias by fitting (M.Y. Chou and H.F. Tsai)

elevation_angle :

Elevtion angle.

h1_km :

Upper boundary of ionosphere height (km). 

h2_km :

Lower boundary of ionosphere height (km).

multiprocess_numbers :

Specifies how many process you want use for calculate GPSTEC in the same time.
