COMBINATION STRATEGY:
Each centre ephemeris and satellite clock corrections are first transformed to
common reference. The differences between each centre X and Y pole solutions
and the IERS Bulletin A corrected with ITRF inconsistency parameters (cf. IERS
1992 Annual Report,Table II-3,page II-17) are used to rotate the corresponding
ephemeris. If the pole solution is not available for a particular centre, no
such rotations are applied. For each centre, a clock offset and drift, common
for all satellites, are estimated with respect to broadcast clock corrections.
These offsets and drifts are used to align each centre satellite clock
corrections to GPS time. The resulting 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 orbit weights are computed from
the absolute deviation to the unweighted average orbit after the estimation of
a 7-parameter Helmert transformation. The clock weights are computed from the
absolute deviation to the unweighted average clock corrections after estimation
of offsets and drifts. The above estimations are performed using the L1-norm
robust scheme. Each centre ephemeris are also evaluated individually and
independently from the orbit combination by using week long arcs. The ERP used
in this evaluation are those submitted by the respective centres supplemented
with IERS Bulletin A UT1-UTC values when they are not supplied. 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 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 developed by T. Springer and G. Beutler
during 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:
Beutler, Kouba, Springer, 1993, Combining orbits of the IGS processing
centres, in IGS Analysis Centre Workshop, October 12-14, Ottawa, pp 19-55.
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 Rapid Service Orbit files generated and uploaded into CDDIS @ NASA/GSFC
are:
IGS07480-6.SP3 IGS GPS ephemeris files for days 0-6, week 0748 in SP3 format.
IGS07487.ERP Earth rotation parameters (ERP) associated with ephemerides.
IGS07487.SUM Complete report.
REMARKS on IGS Rapid Service Orbit Combination:
1. Starting with week 0730, the above satellite clock corrections combination
was put in place. The centres used in the combination are EMR, ESA, GFZ and
JPL. The other centres are excluded because they either provide broadcast
clocks (COD) or clock corrections are not provided (NGS & 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. One clock solution was excluded from the combination due to large clock
shifts. The following table lists the exclusions and order of magnitude
of the shifts:
Centre | Day (Date) | Explanation
---------+--------------+---------------------------
ESA | 2 (May 10) | shifts up to ~1000 nsec.
4. State vector resets were modeled for PRN05 and PRN24 on day 3 (May 11)
at 0h00 as well as for PRN20 on day 2 (May 10) at 0h00 to alleviate
modelling problems experienced in the long arc evaluation for all centres.
ORBIT COMBINATION AND EVALUATION STATISTICS:
Most combination statistics are with respect to the combined orbits and consist
of three 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 1.0748.a).
It also displays the computed satellite position sigmas for the combined orbits
(table 1.0748.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 2.0748.0-6). The
third and final 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 3.0748.0-6). 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.
In all tables, 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.
