Dear Colleagues,

Sorry for any duplicate emails, but Jim Ray suggested that we
email both IGS lists.  A new teqc version is available; more
info at http://ls.unavco.org/pipermail/teqc/2008/000739.html

In particular interest for IGS users of teqc, this version
corrects a problem that was detected just last week by Jim,
which is as follows:

For GPS navigation messages collected late on Saturday (GPS
time), mainly the last two hours, the GPS epoch of the message
and the GPS week value in the nav info is incorrectly
advanced by 1 week if the time of transmission value is
non-zero and towards the end of the current week.  This
incorrect behaviour of teqc would occur for raw-to-RINEX or
RINEX-to-RINEX (e.g. RINEX editing).  This has been an undetected
bug in teqc for 9+ years for raw-to-RINEX and for 4+ years for
RINEX-to-RINEX.

It is advised that IGS users of teqc, esp. those who create or
edit RINEX nav files using teqc, upgrade as soon as possible
to correct this problem.

Regards,
--lou
