dear All,

The next official version -- 2019Feb12 -- of teqc is on-line:

As usual, save a copy of your previous teqc executable in case there is some unexpected
problem with the new executable.  Again, I _strongly_ encourage everyone to download
this new version, try it out, and promptly report anything which you think is a bug or
error.  (You may want to review https://postal.unavco.org/pipermail/teqc/2016/002187.html.)

The main changes and fixes since 2018 Dec 12 are given in detail in reverse chronological
order starting at: https://www.unavco.org/software/data-processing/teqc/log/log.html#2019Feb12 --
but here's a brief summary about the main changes between this release and the last one:

- a record/message of a GLONASS navigation message but contains invalid (e.g. zero values)
   for key parameters (such as all XYZ values) should now not be output (e.g. to a
   GLONASS RINEX nav file)

- the '+psp' options (see https://postal.unavco.org/pipermail/teqc/2017/002231.html) now
   output the initial reference position in XYZ coordinates to 0.1 mm resolution (and thus
   using the incremental ENu changes of the '+psp' output and the initial reference position
   the user, with a little scripting, can reconstruct each position output in XYZ or
   geodetic coordinates)

- a small change to the multipath algorithm has been made (discussed in

- the default maximum PRN of an IRNSS SV has been changed from 7 to 14

- some improvements for reading corrupted or fragmentary NMEA ASCII strings (e.g. from
   external units such as met packs) were made

- improvements made for parsing BINEX 0x7f-05 when SVs with unexpected id values are present

- bit 0 and bit 9 are now set for the "data sources" for a Galileo nav message when
   reading Trimble .tgd record 28 or stream record 0x55 where the nav source is I/NAV E1-B

- correction to a few cases in the function that tries to identify a Trimble receiver from
   Trimble's coded receiver id values in various .dat/.tgd records

- identification of Beidou III B1C signal in Trimble .tgd record 27 and stream 0x57-6

As with several past versions, some builds are no longer available with this release:

- any HP-UX builds
- 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.
