Kouba (kouba at geod.emr.ca) Y. Mireault (mireault at geod.emr.ca), F. Lahaye (lahaye at geod.emr.ca) COMBINATION STRATEGY: Starting with GPS week 803, the IGS Rapid orbit combination is done directly in the ITRF without any alignment to the Bulletin A EOP series. Each centre satellite clock corrections are first transformed to a common reference. For each centre, a clock offset and a drift are estimated with respect to broadcast clock corrections using only non-SA satellites. 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 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 computed from the absolute deviation of the initial alignment to broadcast clock for the non-SA satellites, provided these satellites are representative of the clock solution quality of each centre. Finally, a 7-parameter Helmert transformation and clock offset and drift are estimated for each centre with respect to combined solutions and parameters and RMS of fit reported here. All 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 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 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 resulting x and y earth rotation parameters (ERP) associated with the IGS ephemeris files are computed using a weighted average of all available centres (weights are those from the orbit combination). These values are supplemented with the current IERS Bulletin A UT1-UTC values. The Rapid Service Orbit files generated and uploaded into CDDIS @ NASA/GSFC are: IGS08060-6.SP3 IGS GPS ephemeris files for days 0-6, week 0806 in SP3 format. IGS08067.ERP Earth rotation parameters (ERP) associated with ephemerides. IGS08067.SUM Complete report. REMARKS on IGS Rapid Service Orbit Combination: 1. The centres used in the clock combination are EMR, ESA, GFZ and JPL. The other centres are excluded because they either provide broadcast clocks (COD, 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. Centre clock weights were determined using the following non-SA satellites: PRN15 and PRN28 on days 0-4 (Jun 18-22) and PRN12, PRN15 and PRN28 on days 5-6 (Jun 23-24). PRN12 was declared healthy starting on day 5 (Jun 23) at 16:50 (ref. NANU 135-95174). 4. Some clock solutions were excluded from combination due to large clock shifts or outliers that were biasing the combined clock solution, but were kept for the RMS computation. The following table lists the exclusions: Day (Date) | PRN | Centres | Shifts/Outliers -------------+----------+---------+------------------ 0 (Jun 18) | ALL | GFZ | up to ~ 015 ns 1 (Jun 19) | ALL | GFZ | up to ~ 010 ns 5. There was a maneuver of PRN04 on day 4 (Jun 22) (ref. NANU 133-95173). 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. The ESA, SIO and the combined solutions for PRN04 were excluded from the long arc evaluation on day 4 due to unrealistic RMS caused by the maneuver. 6. Some 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. The following table lists the exclusions: Day (Date) | PRN | Centres -------------+------+-------- 0 (Jun 18) | ALL | SIO (a) 1 (Jun 19) | ALL | SIO (a) 2 (Jun 20) | ALL | SIO (a) 3 (Jun 21) | ALL | SIO (a) 3 (Jun 21) | 12 | EMR 4 (Jun 22) | ALL | SIO (a) 5 (Jun 23) | 6,17 | SIO 5 (Jun 23) |22,24 | SIO 5 (Jun 23) | 04 | EMR 5 (Jun 23) | 06 | SIO (a) rotation problems that affected the combined solution (see Table 2). 7. Starting with GPS week 803, the IGS Rapid orbit combination is done directly in the ITRF without any alignment to the Bulletin A EOP series. Since on the average the mean GPS pole agrees within a fraction of mas with the ITRF aligned Bulletin A, this change of IGS combination strategy should not introduce any noticeable discontinuities in the IGS Rapid orbits. 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 1.0806.a). It also displays the computed satellite position sigmas for the combined orbits (table 1.0806.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 2.0806.0-6). 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 3.0806.0-6). 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.
