dear All,

The next official version -- 2018Jun8 -- of teqc is on-line:

Note: The date stamps on the .zip files and on the executables themselves will be
for today, 2018 June 13, but the code -- and therefore the version -- is really for
2018 June 8 when the last code change was made.  (Solaris builds have been in test
mode since June 8 here at UNAVCO.)

As usual, save a copy of your previous teqc executable in case there
is some unexpected problem with the new executable.

The main changes and fixes since 2018 Mar 15 are given in detail in reverse
chronological order starting at:
http://www.unavco.org/software/data-processing/teqc/log/log.html#2018Jun08 --
but here's a brief summary about the main changes between this release and the last one:

- the bug reported in https://postal.unavco.org/pipermail/teqc/2018/002501.html
that was introduced circa 2017 May (when using GPS navigation messages in GPS week
1022 and/or 1023, i.e. mid-Aug 1999) has been fixed

- a secondary bug in the same low-level function as above has been fixed if
(in the unlikely event) using GPS navigation messages in GPS week 0 and/or 1,
i.e. early Jan 1980, has been fixed

- the qc indicator bug for L1, C1 or P1, L2, and C2 data reported in
https://postal.unavco.org/pipermail/teqc/2018/002484.html has been fixed

- group delay time deltas from the navigation messages of GPS, Galileo, Beidou,
and QZSS have been included when doing a qc full (which again slightly improves
teqc's point-positioning in a statically large sampling)

- the ToW proxy field in a Beidou navigation message translated from Leica MDB
now accounts for the 14 seconds between GPST and BDT

- this version has the first official builds for ARM 64-bit; see

As with the 2018Mar15 version, some builds are not available with this release:

- any HP-UX builds (due to a lack of access an HP-UX system for compiling)
- the 32-bit Borland build for Windows; instead, use the Mingw-32 or Mingw-64 bit builds
- the Mac OSX i5 gcc 4.2 64-bit build; instead, use the OSX i5 gcc 4.3 64-bit build
- Solaris Sparc 5.9 builds

If you have any questions, please let me know.
