[IGSMAIL-6547] about the BJNM station in Beijing

[Jim.Ray]

Author: Kun LIANG (forwarded by Jim Ray)

The following information is forwarded for Dr. Liang due to the
current blockage of communications with JPL.  MIT has been producing
BJNM results since GPS week 1646, which has yielded official IGS
coordinate results since then.  However, because a minimum of 2 ACs
are needed for the clock combination, there have been no official
clock products for BJNM yet, which is of primary interest.  The
station is equipped with a Septentrio POLARX3ETR receiver (GPS+
GLONASS+SBAS) and PolaNT_G antenna.  --Jim

Dear Jim,

Hello.

Our site information is as follows.

We have been uploading the Rinex data of this site to KASI (who transfer the
data to CDDIS) and SIO for a long period. Our site is a “timing” station (the
receiver is referenced by the time scale UTC(NIM), the national time and
frequency metrology primary standard for China, realized by one hydrogen
maser steered to a clock ensemble including one cesium fountain). The site
log for this proposed IGS station is available at

http://igscb.jpl.nasa.gov/igscb/station/pendinglogs/bjnm/bjnm_20100713.log

For information of UTC(NIM), please see the Circular T published by BIPM.

Thank you.
Kind regards,

Kun Liang
NIM,China
