gamit data processing - 3. Configuration file

1. Control file

1. Station list sites.defaults

Add the stations to be processed into the table under test/tables, including IGS stations and local stations, and determine the project name. Then set a link to site.defaults under the working folder 2013 (the link can be set uniformly at the end) .

( gedit **.file can solve changing files without permission )

ln -s ../tables/sites.defaults ./sites.defaults . ln -s sets the link in the current directory, ../tables/sites.defaults sets the link to sites.defaults .

2.station.info

(1) Method 1

Under the rinex folder:

First create the station.info file , copy the file header from an existing station.info file to the station.info file of the new calendar ,

Enter rinex in the terminal, use the command sh_upd_stnfo to generate, such as sh_upd_stnfo–files *.13o

Copy the generated station.info to the talbes folder.

(2) Method 2 

Create a sitelist file in the test/tables folder, enter the name of the test station (space for the first letter of each line), ( cp -r sitelist /home/zhao/desktop/test/tables )

Then open tables in terminal ,

 sh_upd_stnfo -l sitelist

After executing the above code, the last line shows: generate a station.info.new, at this time, it will be renamed station.info, and the original station.info link will be deleted at the same time

sh_upd_stnfo -files ../rinex/*.13o

Execute the above update code,

Update the link to station.info in the test/2013 folder (the link can be set uniformly at the end).

3. Approximate coordinate file lfile

Enter the rinex directory,

grep POSITION *.13o > lfile.rnx

rx2apr lfile.rnx 2013 032

gapr_to_l  lfile.rnx.apr lfile.    '''' 2013 032 

Then copy the lfile file to test/tables,

 cp -r lfile. /home/zhao/desktop/test/tables

And set the link under the working directory 2013 folder:

ln -s ../tables/lfiles. (You can set the link uniformly later)

2. Configuration files   process.defaults and sittbl. and sestbl. files

1. Configure process.defaults

Set the link, enter the test/2013 folder in the terminal, ln -s ../tables/process.defaults (you can set the link of tables uniformly at the end)

2. Configure the coordinate constraint file sittbl .

Strong constraints on high-precision known coordinates, loose constraints on the coordinates of the points to be found

   

3. Configure sestbl. Correct the model file

Choice of Experiment = BASELINE ; BASELINE/RELAX./ORBIT Baseline processing type

If it is to solve the baseline, it is recommended to choose BASELINE , that is, fixed orbit.                           The general choice is the relaxation solution

Choice of Observable = LC_AUTCLN ; LC_AUTCLN (default), LC_HELP Observable selection type

(meaning that the observations are a linear combination without an ionosphere , the final solve result uses the ambiguity parameter , and the broad-phase ambiguity solved by autcln uses pseudoranges, the new eigenvalues ​​in Release 10.2, and the current the default value.)

Use otl.grid = Y        Use atml.grid =   N （Y）    Use atl.grid = N （Y）  ; Ocean tidal loading grid file,    海潮改正

3. Setting the link

1. Link the brdc, igs, rinex files to the working directory 2013 folder, enter the test/2013 file directory,

ln -s ../brdc/*.13n ./      

ln -s ../igs/*.sp3 ./      

ln -s ../brdc/*.13o ./      

2.Tables set the link , enter the test/2013 file directory, (should be the second)

links.day 2013 032 test (the first 2013 is year, the second is doy 032, and test is the project directory)

Use the ls -al command to view the broken link, and then use the ln -s statement after the table in the previous section to relink.
