we stopped submitting rinex v2 data from LHAZ today due to limited
bandwidth of internet connection. This may help making rinex v3
submitting more reliable.
The Firmware of site LHAZ was updated to version 4.31/6.712
An updated site log file has been submitted to IGS.
FW 4.31/6.712 is a firmware version released on demand to enable
optimized all in view tracking on GR10/GR25 receivers, where this
is specifically required.
Contact Leica Geosystems Heerbrugg for further information.

My colleague Uwe Hessels upgraded the firmware
in the LEICA GR25 in the LHAZ GNSS Permanent Tracking
Station Lhasa, Tibet, China from 3.22/6.521 to
3.22/6.522, 2016-05-10 07:45 UTC.
And we detected a mysterious trouble.
From 2016-03-16 12:00 UTC until 2016-05-11 12:00 UTC
the wrong antenna serial number 725299 was reported
for the LEIAR25.R4 antenna and the Radome LEIT in the
RINEX-Headers and in the LHAZ Site Information Form
(sitelog).
The true antenna serial number for the LEIAR25.R4 antenna
and Radome LEIT is 08430006.
Since 2016-05-11 12:00 UTC the true serial number 08430006
for the LEIAR25.R4 antenna and the Radome LEIT is reported
in the RINEX Headers.
The data files Data Files from DOY 079 15:00 UTC until
DOY 081 01:00 UTC and at DOY 081 from 11:00 UTC until
13:00 UTC from the LHAZ GNSS Permanent Tracking
Station Lhasa, Tibet, China are not available.
The data files from DOY 334 13:00 UTC until
DOY 335 01:00 UTC from the LHAZ GNSS Permanent
Tracking Station Lhasa, Tibet, China are not available.
The Internet connection to the LHAZ GNSS Permanent
Tracking Station Lhasa / Tibet / China is interrupted.
We did not get the data files since DOY 081 04:00 UTC.
The data DOY 255 from 06:00 UTC until 15:00 UTC
from the LHAZ GNSS Permanent Tracking Station
Lhasa, Tibet, China are not available.
On request of Mr. Nacho Romeo, ESA/ESOC and
IGS Infrastructure Committee, our colleagues removed
the radome from the antenna in the LHAZ GNSS Permanent
Tracking Station Lhasa, Tibet, China, today 2013-09-12,
08:10 UTC.
The data files DOY 247 from 01:00 UTC until 09:00 UTC from the LHAZ GNSS Permanent Tracking Station Lhasa, Tibet, China are not available.
