Final IGS Orbit Combination - Week 0939 (Jan 04, 1998 - Jan 10, 1998)

COMBINATION STRATEGY:
Starting with GPS week 860, the IGS Final orbit combination is done directly
in the ITRF without any alignment to the Bulletin B EOP series.
Each centre satellite clock corrections are first transformed to a common
reference. One of the following two methods can be used (the REMARKS section of
this report gives which method is used):
[1] For each centre, a clock offset and a drift are estimated with respect to
the broadcast clock corrections using only non-SA satellites;
[2] A chosen reference centre is aligned to the broadcast clock corrections
using all satellites. All other centres are then aligned to that reference
centre.
The offsets and drifts are used to align each centre satellite clock
corrections to GPS time. Ephemerides and clock corrections are then combined
as weighted averages computed over all centres. Each centre is given a
position weight and a clock weight. The position weights are computed from
each centre's absolute deviation to the unweighted average orbit after the
estimation of a 7-parameter Helmert transformation. The clock weights are
either computed from [1] the absolute deviation of the initial alignment to
broadcast clock for the non-SA satellites, or [2] from the absolute deviation
of centre's aligned clock corrections with respect to the unweighted mean.
Finally, a 7-parameter Helmert transformation and clock offset and drift are
estimated for each centre with respect to the combined solutions and parameters
and RMS of fit reported. All the above estimations are performed using the
L1-norm robust scheme.
Each centre ephemerides are also evaluated individually and independently from
the orbit combination by using week long arcs. The Earth Orientation Parameters
(EOP) used in this evaluation are those submitted by the respective centres.
The IGS combined orbits/clocks and all centres providing both orbit and clock
solutions are further evaluated by an independent point positioning (navigation)
program developed at NRCan. This is primarily intended for testing clock
solution precision as well as the orbit/clock consistency.
Like the clock solutions broadcast in the navigation message, the combined
satellite clocks are corrected for the periodical relativistic correction (see
e.g. GPS interface Control document ICD-GPS-200, p.73):
-2*(X.V)/c,
where X and V are the inertial sv state and velocity vectors and c is the speed
of light. Also for compatibility, no satellite L1/L2 delay calibration should be
applied.
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:

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:
IGS09390-6.SP3 IGS GPS ephemeris files for days 0-6, week 0939 in SP3 format.

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 satellites:
Day | PRN list | Ref. Centre
-----+----------+-----------------
0-6 | All | COD (see note below)
Note: A chosen reference centre 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. 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 (Jan 06) | 00:00:00 | 14 | All | Modeling problems (a)
3 (Jan 07) | 00:00:00 | 16 | All | Modeling problems
5 (Jan 09) | 00:00:00 | 23 | All | Modeling problems (b)
(a) Satellites PRN14 was excluded from long arc evaluation on days 4-6
for all centres due to unrealistic RMS.
(b) Satellites PRN23 was excluded from long arc evaluation on day 0
for all centres due to unrealistic RMS.
7. PRN13 was included in this week's Final combination although its status is
still UNHEALTHY. Users are reminded to use it with extreme caution.
PRN13 was launched on Jul 23 1997 (wk 0915 day 3) at 03:43 UT. It resides
in slot F-5 (ref. NANU 088-97206). A Follow up NANU will be sent once the
navigation payload on PRN13 is usable.
8. A new clock combination strategy was implemented starting this week (wk 938).
It is based on radial orbit differences of the AC orbit solutions with
respect to the IGS combined orbits. The algorithm generally gives better
clock combination RMS and more importantly, gives a better igs orbit/clock
consistency.
ORBIT COMBINATION AND EVALUATION STATISTICS:
Most combination statistics are with respect to the combined orbits and
consist of five parts. The first, Table 1, summarizes all statistics for the
week. It contains means and standard deviations over the week of satellite
ephemeris and clock correction transformation parameters for each centre
(table 1.0939.a). It also displays the computed satellite position sigmas for
the combined orbits (table 1.0939.b). The second part, Table 2, contains the
complete ephemeris and clock correction transformation parameters (includes
both the apriori and a posteriori values) for each centre and each day
(tables 2.0939.0-6). The third part, Table 3, contains two types of daily RMS
for each satellite and centre, along with the computed satellite position
sigmas for the combined orbits (tables 3.0939.0-6). The first type of
satellite RMS is based on orbit combination and the second RMS type is a result
of the 7-day arc evaluation of each centre ephemerides. The fourth part,
Table 4, is a weekly summary of the daily precise navigation summaries for
centres providing both orbit and clock solutions. It contains weekly station
RMS w.r.t. the initial coordinates for the Latitude, Longitude and Height
components for up to three IGS stations (table 4.0939). The fifth and final
part, Table 5, is similar to Table 4 and contains daily precise navigation
statistics (tables 5.0939.0-6).
In tables 1-3, the most important statistic which is meaningful for intra
centre/satellite analysis is labeled WRMS. It is a weighted RMS where
normalized weights are based on accuracy codes given in the SP3 files, and
should not be affected by downweighted/problem satellites when acknowledged by
individual centres in their SP3 file.
