# This is an example and template of a generic track command file. It assumes
# that RINEX observation files for five sites, one fixed ("FFFF") and four
# kinematic ("AAAA", "BBBB", "CCCC" and "DDDD"), SP3 orbits and IONEX files
# exist in the current working directory for the day to be processed (2019-100
# in this example).
#
# Before running track using this template users must do the following, based
# on their own experiment needs:
# 1. Download or copy RINEX observation files for all sites, e.g.
#    "sh_get_rinex -archive cddis sopac unavco -yr 2019 -doy 100 -sites ffff aaaa bbbb cccc dddd"
# 2. Download precise orbits, e.g.
#    "sh_get_orbits -orbit igsf -yr 2019 -doy 100 -nofit"
# 3. Download IONEX files, e.g. "sh_get_ion -yr 2019 -doy 100"
# 4. Calculate the GPS week and day corresponding to the year and day to be
#    processed, e.g. "doy 2019 100" gives GPS week 2048, day 3.
# 5. Define (a) accurate a priori coordinates for each site under "site_pos",
#    (b) a priori constraints consistent with their accuracy under "site_stats"
#    and (c) antenna (and, optionally, receiver "PCN" code) information under
#    "ante_off".
# 6. Change the "interval" to match the data being processed.
# Users may also ultimately want or need to adjust solution parameters, e.g.
# "float_type", or output options, e.g. "out_type", "sum_file", etc.
# See ~/gg/help/track.hlp for more information.
#
# track may then be run with a command such as:
# track -f track.cmd -d 100 -week 20483 -s 2019 19 ffff aaaa bbbb cccc dddd >& ffff_2020-100.log
