Subject: Westford WES2 and WFRD Status

The WES2 and WFRD GPS systems went down on July 30 (D211) around 17:27UTC due to
a power shortage at the Observatory. We expected it to be brought back on August 4.

Dear Users:

The CDDIS will be unavailable to the user community on Tuesday,
August 9, 1994 from 12:00 noon until ~4:00 p.m. (EDT). A new disk
drive will be installed at that time. I regret any inconvenience this
down-time will cause the user community.

Regards,

Subject: Wk 751-754 Final IGS orbits


*******************************************************************************

IGS Final orbits/clocks completed and put onto CDDIS (Weeks 751 - 754)
( May 29 - June 25, 1994)
*******************************************************************************

According to the recommendations of the Analysis Centre Workshop the IGS
Rapid Orbits were recomputed using up to date orbits and the final EOP values
of Bulletin B, published by IERS. ( Daily values, page 2 of Bull. B were
used). The EOP were corrected for the difference between the IERS pole series
and ITRF as published in the IERS 1992 Annual Report (p. II-17, Table II-3),
so both the IGS orbits and associated ERP files are consistent with ITRF92
(current epoch).

We have downloaded all submitted ephemeris and ERP files from CDDIS before
the final orbit/clock combination to ensure that the sets are complete and up
to date. In the final combination we have largely followed the actions taken
during the Rapid orbit generation and since there were very few orbit
resubmissions, both the IGS Rapid and Final orbits are virtually same except
for the the orientation difference (the current Bull.A and final Bull.B).
Orbit evaluation are also nearly the same, since we used centre specific ERP
in these long arc evaluations. For more information see the corresponding
summary files on CDDIS.

Starting with the GPS week 742 a new clock combination scheme was put in
place for the final orbit/clock combinations. The clock solution alignment
and centre clock weight assignment are based on non SA broadcast satellite
corrections only (PRN12, 15, 20). This should result in more realistic and
objective clock weighting than employed before, provided that the non SA
satellites are representatives of each centre clock solution quality.

PRODUCTS GENERATED:

The resulting final IGS ephemeris and clocks are in daily files in the SP3
format. The sat. orb. accuracy codes displayed in the headers are based on
weighted RMS for each satellite. Note that each file contains all the submitted
satellites. If satellite or centre had to be excluded from the combination it
is noted in the summary file along with the reason for doing so.

The IGS FINAL ORBIT files generated and uploaded into CDDIS @ NASA/GSFC are:

IGS07510-6.SP3 IGS GPS orbit/clock files for days 0-6, week 0751
IGS07520-6.SP3 IGS GPS orbit/clock files for days 0-6, week 0752

The tracking data from 3:50 UT on DOY 226 to 4:00 UT on DOY 227
at TSKB was lost because of the trouble of TurboRogue antenna.
The trouble was fixed by replacing the antenna to another one
(Serial Number 105).
The APR is exactly at the same position as before.

Pamatai (Tahiti) :
----------------

Since July 26 01:30 UT the Rogue SNR-800 GPS receiver at Pamatai
is running with Meenix 7.8 software.
Unfortunately, a previous attempt to upgrade the software was done on July 19
but the memory manager had not been reset. The data from July 19 to July 25
are consequently definitely lost.
