3.4 Global Files
These files are global in the sense that they can be used for many experiments over the time interval
for which they are valid (usually for at least a year). The name of the files must be exactly specified
as indicated below. All of these are found in gg/tables, but except for ftp_info, a link to (or copy of)
these files must be in each day directory.
ftp_info : Table of addresses and protocols for downloading files from external archives.
Type : ASCII
Created by : MIT, and modified by user as needed
Input to : sh_get_hfiles, sh_get_nav, sh_get_orbits, sh_get_rinex, sh_get_stinfo, sh_update_eop
rcvant.dat : Table of correspondences between GAMIT 6-character codes and the full (20-
character) names of receivers and antennas used in RINEX and SINEX files.
Notes : See Section 4.3 and Appendix 7
Type : ASCII
Created by : MIT, SIO, or user from IGS standards
Input to : MODEL (eventually XTORX and HTOSNX)
guess_rcvant.dat : Used optionally by sh_gamit to determine the GAMIT code from non-exact 20-
character names of receivers and antennas in the RINEX header.
Notes : See Chapter 10.
Type : ASCII
Created by : MIT, with modifications by user as needed.
Input to : MSTINF2, UPDATE_STNFO
antmod.dat : Table of antenna phase center offsets and, optionally, variations as a function of
elevation and azimuth.
Format : Two version allowed, one is GAMIT-specific and soon to be obsolete; the other
is IGS ANTEX.
Notes : See Section 4.3, 5.2 and Appendix 7
Type : ASCII
Created by : MIT
Input to : MODEL
