Final IGS Orbit Combination - Week 0915 (Jul 20, 1997 - Jul 26, 1997)

COMBINATION STRATEGY:
For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS09157.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 integrated into IGS 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:
IGS09150-6.SP3 IGS GPS ephemeris files for days 0-6, week 0915 in SP3 format.
IGS09157.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
----+---------
0-3 | 15
4 | all (a)
5-6 | 15
(a) A different strategy for clock alignment on day 4 was chosen since the
alignment using PRN15 gave inapropriate weights and unrealistic clock RMS.
We used the following strategy: a chosen reference centre (in this case
EMR) is aligned to the broadcast GPS clocks using all satellites;
all other centres are then aligned to that reference centre. The clock
weights are computed from the absolute deviation of centre's aligned clock
corrections with respect to the unweighted mean.
6. New clock offsets and drifts were estimated for centres showing reference
clock resets. Note that only the first clock offset and drift are output
to the summary file. However, the clock combination and the listed RMS
include all the clock segments. In summary, the following clock
shifts/resets were noticed and accounted for:
Day | Centre | Time | Jump
----+--------+--------+-------------
4 | GFZ | ~14:30 | ~ -1850.1 ns
7. The following orbit solutions were excluded from the combination because
they were biasing the weighted average (generally indicated by long arc RMS).
They were still used for statistics computation.
Day | Centre | PRN list
----+--------+---------------
0-3 | EMR | ALL (High Rotations - see Table 2)
2 | NGS | ALL (High Rotations - see Table 2)
5 | EMR | ALL (High Rotations - see Table 2)
3 | COD | 14
6 | ESA | 16
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 22) | 00:00:00 | 18 | All | Modeling problems (a)
3 (Jul 23) | 00:00:00 | 14 | All | Modeling problems (b)
4 (Jul 24) | 00:00:00 | 16 | All | Modeling problems (c)
5 (Jul 25) | 00:00:00 | 19,23 | All | Modeling problems
(a) Satellite PRN18 was excluded from long arc evaluation on day 2 for
all centres due to unrealistic RMS.
(b) Satellite PRN14 was excluded from long arc evaluation on days 0,3,6 for
all centres due to unrealistic RMS.
(c) Satellite PRN16 was excluded from long arc evaluation on days 3,5-6 for
all centres due to unrealistic RMS.
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.
10. PRN13 was launched on 23 July 1997/wk915 day 3 at 03:43 UT. It will reside
in slot F-5 (ref. NANU 088-97206). A Follow up NANU will be sent once the
navigation payload on PRN13 is usable.
