Final IGS Orbit Combination - Week 0912 (Jun 29, 1997 - Jul 05, 1997)

COMBINATION STRATEGY:
For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS09127.SUM).
SOFTWARE:
The weighted average software used was originally developed by T. Springer
and G. Beutler in 1993. The GPS long arc orbit analysis software used here for
individual centre ephemeris evaluation was developed by Beutler et al. at the
Astronomical Institute of the University of Bern (AIUB). For more details on
the orbit combination and complete references for both software see:

Analysis Centers, Bulletin Geodesique, 69, pp 200-222.

PRODUCTS GENERATED:
The resulting average ephemeris and clocks are output to daily files in SP3
format. The satellite accuracy codes displayed in the header are based on the
weighted RMS for each satellite. Note that each file contains all the
satellites that appear in any of the centre ephemeris files. If a satellite or
centre was excluded from combination, a note in the REMARKS section of this
report will identify the exclusion and the reason.
The resulting x and y earth rotation parameters (ERP) associated with the IGS
ephemeris files and their rates (xrt, yrt) are computed using a weighted average
of all available centres (weights are those from the orbit combination).
Pole rate combination uses only centres providing estimated pole rates.
Starting with GPS wk 0894, IGS LOD combinations were implemented in the
Final IGS solutions. AC LOD biases with respect to Bulletin A are estimated
using Bulletin A most recent 3 weeks (21 days), i.e. up to 5 days prior to
the last non-predicted day of Bulletin A. AC LOD biases are removed and the
new AC bias-free LODs are used to compute a weighted IGS LOD which in turn
is used to integrate UT1-UTC. The starting UT1-UTC value is chosen as
Bulletin A fifth day prior to its last non-predicted day. Both IGS LOD and
UT1-UTC values are printed in the IGS Final erp file.
The Final Orbit files generated and uploaded into CDDIS @ NASA/GSFC are:
IGS09120-6.SP3 IGS GPS ephemeris files for days 0-6, week 0912 in SP3 format.
IGS09127.ERP Earth Rotation Parameters (ERP) and their rates as well as
Universal Time (UT1-UTC) and Length Of Day (LOD) associated
with IGS ephemerides.

REMARKS on IGS Final Orbit Combination:
1. The centres used in the clock combination are COD, EMR, ESA, GFZ and JPL. The
other centres are excluded because they either provide broadcast clocks (NGS)
or clock corrections are not provided (SIO). The clock information not
used is still compared to combination for completeness.
The value of 999999.999999 microseconds, according to the sp3 format
convention, is used to signify that no clock solution is available and
therefore must not be used.
2. Only the GFZ "exact" clock corrections (one epoch out of two) are included
in the combination and RMS computation (no "interpolation" values).
3. Rapid ("IGR") orbits/clocks are included in the combination for statistics
only.
4. The following centre clock solutions, which provide broadcast clock
corrections, were excluded from the combination but kept in the combination
statistics:
-> Centre: NGS
5. Centre clock weights were determined using the following non-SA satellites:
Day | PRN list
----+---------
0-1 | 15
2 | all (a)
3-6 | 15
(a) Since PRN 15 was maneuvered on day two, no centre except ESA submitted
a solution for that satellite. It was therefore not possible to align
all clocks using PRN 15, the only non-SA satellite. We used a different
strategy where a chosen reference centre (in this case COD) is aligned to
broadcast GPS clocks using all satellites and then all other centres are
aligned to the reference centre. The clock weights are given by the
latter alignment and the reference centre is given the smallest weight
computed.
6. The following clock solutions were excluded from the combination because
they were biasing the combined clock solutions (large clock shifts/outliers)
but were kept for the RMS computation. Note that starting with week 860,
Centres with clock RMS higher than 2 ns are excluded from the clock
combination if they bias the combined clock solution. This will make IGS
clock precision more comparable to the best ACs.
Day | Centre | PRN list
----+--------+---------------
2 | EMR | ALL
7. The following table lists all maneuvered satellites for this week.
The ESA solution which modeled the maneuver is provided for that satellite
on that day as the combined solution. An associated accuracy code of 0
(unknown) was given since there was no redundancy. These satellites were
excluded from the long arc evaluation on these days due to unrealistic RMS
caused by the maneuver.
PRN | Day | Date | Ref. NANU

15 | 2 | 1997_07_01 | 079-97182
10 | 3 | 1997_07_02 | 080-97183
8. State vector resets were modeled for the following satellites to
alleviate the effects of modeling problems, experienced by all centres,
in the Long Arc (LA) process:
Day (Date) | TIME | PRN | Centres | Reason
------------+----------+-------+----------+-------------------
2 (Jul 01) | 00:00:00 | 15 | ALL | Maneuver
3 (Jul 02) | 00:00:00 | 10 | ALL | Maneuver
3 (Jul 02) | 00:00:00 | 23 | ALL | Modeling problems
6 (Jul 05) | 00:00:00 | 14 | ALL | Modeling problems
9. Centre specific UT1-UTC values for NGS were not used in the long arc
evaluation. Smaller RMS were obtained when UT1-UTC values from Bulletin A
were used.
