Lecture 6: Tuning the GAMIT data cleaning and cycle slip repair program AUTCLN      India_lec06.pdf           India_lec06.html

Lecture 7: Problems encountered in automatic data processing and some solutions       India_lec07.pdf           India_lec07.html

Lecture 8: Tutorial session aimed at running all of the three years of data with four days of data per annual experiment.

 

Wednesday January 30

Lecture 9: Analysis of the overnight runs.  Most common problem was not accounting for the antenna names in the rinex files (name given as unknown and guess_rcvant.dat file in templates needed to be modified to accept “unknown” to be a TRMDMG antenna.

Lecture 10: GLOBK theory and solution types.          India_lec10.pdf      India_lec10.html

Lecture 11: Applications of GLOBK and its ancillary programs         India_lec11.pdf      India_lec11.html

Lecture 12: Automatic processing with GLOBK: sh_glred.  Lecture run in tutorial mode with direct connection to C-MMACS computers. India_lec12.pdf      India_lec12.html

 

Thursday January 31

Lecture 13: GLOBK velocity solutions and use of GLORG to realize a coordinate system.      India_lec13.pdf           India_lec13.html

Lecture 14: Plotting and analysis programs used with GLOBK.         India_lec14.pdf      India_lec14.html

Lecture 15: Repeatability runs and summary programs.  This lecture was run directly connected to the C-MMACS o200 computer to look at the quality of the GLOBK repeatability runs.

Lecture 16: Tutorial session with students setting up final runs of GLOBK on data.  Some students also re-ran GAMIT with phase center models turned off, and other re-ran GAMIT using IGS orbits as apriori rather the SOPAC g-files that were used in the original runs

 

Friday      February 1

Lecture 17: Utility programs and scripts contained in ~/gg/com, ~/gg/kf/utils and ~/gg/gamit/utils.    India_lec17.pdf           India_lec17.html

Lecture 18: In class tutorial using the use of the utility programs to analyze the results from the analyses performed for the class.

Lecture 19: Kinematic processing program TRACK.  Class also included analysis of some of the data processed in the class with TRACK.    India_lec19.pdf      India_lec19.html

Lecture 20: Final wrap-up session with question and answer period.
