CRITICAL UPDATE: Access to the NGS Public FTP Service for the NOAA CORS Network
was discontinued on 16 August 2021, so NOAA CORS data now need to be accessed
via secure HTTP at https://geodesy.noaa.gov/corsdata/ (see
https://content.govdelivery.com/accounts/USNOAANOS/bulletins/2ea199f). GeoNet
New Zealand also switched off its FTP server on 21 December 2021 (see
https://www.geonet.org.nz/data/types/geodetic).
Similar changes will soon take effect at BKG, which will switch off its FTP
server “in the not so long term” (see https://igs.bkg.bund.de/access), and at
UNAVCO, which will switch off its FTP server on 1 June 2022 (see
https://www.unavco.org/data/gps-gnss/file-server/file-server-transition-notice.html).
Each of these data centers is already operating a secure HTTP server.
All of these transitions to HTTP from FTP are accommodated in an update to
com/sh_get_rinex, which we recommend all users download and start to use as soon
as possible to continue downloading data from BKG, GeoNet New Zealand, NOAA CORS
or UNAVCO. We also recommend adding a line to a ~/.netrc file (in your home
directory) to provide the SOPAC server with the information it requests (see
http://garner.ucsd.edu/), e.g.:
machine garner.ucsd.edu login anonymous password
where is your preferred email address (do not use any quotation marks or
brackets around your email in this line in .netrc).
We continue to try to keep track of the continuing upgrade and transfer of
file servers to HTTP from FTP and will make further updates to the scripts as
necessary.

Summary features added 17-May-21:

New version (5.21) of glorg which has added option to modify station coordinate
covariances to account for the number of times stations are used in multiple
analysis center combinations on daily solutions. Feature invoked with
“org_opt BALN”.

kf/includes/kalman_param.h: Added documentation for new version of glorg.
TAH 20210517

com/sh_dem: Updated URLs for downloading SRTM30 (version 2.1), and SRTM3 and
SRTM1 (version 3); SRTM3 and SRTM1 version 2.1 seems no longer available.
These new URLs require a NASA Earthdata login in a ~/.netrc file, exactly the
same as sh_get_rinex, sh_get_nav, sh_cddis (called by sh_get_orbits),
sh_get_ion, sh_get_met, sh_update_eop, sh_get_ultrarapids and sh_sel_rinex
(see 2020-08-31 record, and 2020-09-04, 2020-09-17, 2020-09-20 and 2020-10-21
updates for details). MAF 20210513

kf/glorg/Makefile.generic: Added balance_cov.f to glorg library. TAH 20210510

kf/glorg/balance_cov.f: New routine added to glorg to account for multiple uses
of stations when combinations from multiple analysis centers (ACs) on one day
are made (IGS type-combined solutions). Satellite PCO estimates are also
modified by number of ACs in combination. TAH 20210509

kf/glout/write_glb_he.f: Modified to add line if BALN option has been used.
TAH 20210509

kf/globk/decode_prt.f: Added new option BALN to balance networks so that
stations used multiple times do not have their standard deviations reduced by
sqrt(N). The operation is only done in the output stage of glorg. If the
“out_sol” command is used in glorg to outout the combined binary h-file (.CON
extent), the balancing operation has been performed. (Standard “out_glb”
binary h-files from globk is not effected). When using the .CON h-files,
“apr_rot” should be used to allow rotation of the frame resolved H-file.
These .CON files also have the translations resolved. If converted to SINEX,
the -d=TR can be used to add back rotation and translation uncertainty. Scale
should not be estimated when frame resolved H-files are produced because the
scale will be fixed at the reference frame values in these files. TAH 20210509

com/sh_exglk: Updated time-tag uniqueness for scratch files to avoid possible
clashed during parallel runs. TAH 20210507

CRITICAL UPDATE: Access to the CDDIS global data archive via anonymous FTP was
discontinued after 31 October 2020. CDDIS now needs to be accessed via
authenticated secure HTTP or anonymous secure FTP. We have updated the following
eight scripts to accommodate this change (see 2020-08-31 record, and 2020-09-04,
2020-09-17, 2020-09-20 and 2020-10-21 updates, below): sh_get_rinex, sh_get_nav,
sh_cddis (called by sh_get_orbits), sh_get_ion, sh_get_met, sh_update_eop,
sh_get_ultrarapids and sh_sel_rinex. Each of these updated scripts must be
downloaded to your ~/gg/com/ directory to continue to access the CDDIS archive.
We recommend that you register to use authenticated secure HTTP by creating an
Earthdata account at https://urs.earthdata.nasa.gov/. Then you must include this
information in a “.netrc” file (note the dot at the beginning of the file name)
in your home directory with the following line:
machine urs.earthdata.nasa.gov login password
where is your Earthdata username and is your Earthdata
password (do not use quotation marks or brackets around your or
in this line in .netrc). If you do not wish to create an Earthdata
account you may still access the CDDIS archive via anonymous secure FTP but this
requires your system to have curl version >= 7.11.0 or wget version >= 1.18.
See https://cddis.nasa.gov/Data_and_Derived_Products/CDDIS_Archive_Access.html
for more information.

• Changes made to increase Glonass data yields due to issues with RINEX 2
  headers.
• New cddismgex archive to get RINEX 3 data from CDDIS MGEX area (needed for
  data collected before MGEX data was saved in the same directories are GPS
  data.

epochs during the gap (makex and maybe model fatals). Cleaned up indenting
around modified code. TAH 20200524

com/sh_sp3fit: Incorporated GNSS into decoding svs_exclude.dat. Line format is
now Gnn, Rnn, etc. When gnss==G, old nn only designation allowed. Note: doy is
3-digit. TAH 20200524

com/sh_gnss_sel: Fixed issue with hardwired date in find command. Updated help
message. TAH 20200524

com/sh_preproc: Made lfile test name more unique by adding expt and doy to
temporary name (conflicts in parallel runs could lead to zero length
lfiles). TAH 20200523

kf/ctogobs/ctogobs_dd.f: Fixed error in replaced integer do loop. TAH 20200520

tables/otl_FES2014bM_MRG.list: Merged FES2014 list from otl_FES2014bM_IGS.list
and otl_FES2014bM.list generated at Chalmers University. TAH 20200520

kf/track/{theory.f, get_miss.f, track_com.h}: Modified behavior of USE_BLQ
command to allow solid-Earth tide model to be specified (IERS2010 or default
analytic model) and to turn off model completely (NOETIDE). NOBLQ needs to be
given as argument to turn off ocean-tide model (structured this way for
backwards compatibility). TAH 20200520

Wednesday 20 May 2020

com/sh_get_grids: New script from S. McClusky to download grids from
ftp://everest.mit.edu to the current working directory. MAF 20200520

kf/update_pmu/igs_to_pmu.f: Added feature to have UT1 in the PMU file be
generated by integrating the LOD values rather than using the globk estimates.
This can be useful when generating Earth fixed SP3 files from inertial t-
files. TAH 20200518

com/sh_gnss_sel: New script to add GNSS networks to sites.default.yyyy.ddd
files. Assumes that the rinex files have been downloaded so that data types
available in the files can be determined with scan_rinex. TAH 20200518

com/sh_plotvel: Added coast line specification -clw option. Default remains
unchanged. TAH 20200515

com/sh_network_sel: Added feature to update existing sites.defaults file with
additional net names added. Removed default apr_file name. Useful for having
GPS and GNSS networks separate. TAH 20200515

com/sh_rx2apr: Forced rinex header coordinate extraction if RINEX 3 files which
svpos and svdiff can’t read. Cleaned up site name extraction when directory
included in site file name. Cleaned up indentation. Remove spherical l-file
output. TAH 20200518

com/sh_rx2apr: Added RINEX 3 trap to use approximate coordinates in RINEX header
if file given with “-site” option is RINEX 3 or results of SVPOS if file given
with “-site” option is RINEX 2 but file given with “-ref” option is RINEX 3.
MAF 20200517

tables/svs_exclude.dat.nanu: Updated following USCG NANU 2020023. MAF 20200515

tables/rcvant.dat: Added STONEX S980 (STXS98), STONEX S980A (STX98A) and STONEX
S990A (STX99A) receivers, and STXS990A (STX99A) antenna. MAF 20200514

Summary of added features and updates. Tuesday, May 12, 2020

• The Gipson 2017 VLBI model updated. Default: added UT1 libration term and
  keeps the IERS2010 model.
• New scan_rinex utility added assess observables in RINEX 2 and RINEX 3 files.
• Added pre-fit millisecond clock jump scanning and fixing in autcln. Normally
  not needed and default is not to do it. New status report option to look at
  pre-scan clock residuals. Useful if lots of BAD PREFIT data delete messages.
• Added lower frequency selection for GNSS processing (makex and sh_gamit -lfreq
  option) so G5, C7, E6/7/8 are options of lower frequency instead of G2, C6 and
  E5.
• Updated autcln to avoid errors in autcln/solve when some stations are missing
  a frequency band completely.

libraries/includes/freq_def.h: Fixed small error in E8 frequency (0.001E6 Hz)
(impact MW-WL looked like LG in cview. TAH 20200512

gamit/makex/settyp.f: Added E8 to list of valid frequency. TAH 20200512

files need to be downloaded before sh_get_orbits is run. TAH 20200511

kf/ctogobs/{ctog_utils,read_cfheads}.f: Updated save non-zero frequencies when
c-files are read. Solve has problems if the first c-file is missing a
frequency band and autcln could have problem if last c-file is missing
frequencies. This can happen with GNSS data missing standard frequencies at
some sites. TAH 20200511

kf/ctogobs/set_freqs.f: Moved code that saves frequencies to ctog_utils.f and
read_cfheads.f. TAH 20200511

be passed. For example C7 for the gnss runstring parameter will select C7 as
lower frequency instead of default C6. G5, E6, E7 and E8 are also options.
TAH 20200511

gamit/lib/sel_obtyp.f: Added option for lower frequency selection. TAH 20200511

gamit/makexp/makexp.f: Added passing gnsslf string into makex batch file.
TAH 20200511

com/sh_makexp: Added -lfreq option to select lower frequency for G,C and E, e.g.
“-gnss E -lfreq 7” will select L7 (E5b) as lower frequency for Galileo instead
of L5 (E5a). Options allowed are G5, C7, E6/7/8. TAH 20200511

com/sh_preproc: Added -lfreq option (see sh_makexp). Fixed bug with g-file being
checked with “^G” rather than “^$gnss”. TAH 20200511

com/sh_gamit: Added -lfreq option (see sh_makexp); -remakex Y will be needed if
older x-files already exist in processing directory. TAH 20200511

kf/ctogobs/prc_ctog_cmd.f: Added new option to prefit_clk command to remove
millisecond jumps in clocks. Not a common problem but could be useful for some
data. TAH 20200510

version number for autcln. TAH 20200510

kf/ctogobs/fit_igs_clk.f: Limited updating linear fits to clocks with < 100 ns
RMS. Millisecond jumps in clocks can cause high RMS scatters. Corrected
indexing on frequencies (not issue since all frequencies are mapped to common
frequency at this point). TAH 20200510

kf/ctogobs/upd_cf_sd.f: Removed a debug statement. TAH 20200510

kf/ctogobs/Makefile.generic: Added prescan_msj subroutine. TAH 20200510

of these routines have same block of code for HF EOP but some time argument
variable names differ. TAH 20200509

gamit/lib/hfeop_gipson.f90: New module implementing Gipson VLBI model. Libration
and solid Earth terms were in a priori so this model needs these terms added
and is compatible with Desai and Sibios implementation. TAH 20200509

gamit/lib/hfeop_desai.f90: Modified to remove functions and subroutines that are
common to hfeop_gipson.f90. TAH 20200509
