Gendt (gendt at gfz-potsdam.de), Th. Nischan ( nisn at gfz-potsdam.de) 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 that uses both phase and pseudorange data. 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 [distance unit], 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: Beutler G., Kouba J. and T.

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: igs1421[0-6].sp3 IGS GPS ephemeris files in SP3 format. igs1421[0-6].clk IGS GPS satellite and station clocks in SP3 format. igs1421[0-6].cls IGS GPS clock combination summary report. igs14217.erp Earth Rotation Parameters (ERP) and their rates as well as Universal Time (UT1-UTC) and Length Of Day (LOD) associated with IGS ephemerides. igs14217.sum Complete report. REMARKS concerning the IGS 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. Rapid (IGR) orbits/clocks are included in the combination for statistics only. 3. The following centre clock solutions, which provide broadcast clock corrections, were excluded from the combination but kept in the combination statistics: -> Centre: NGS 4. The following clock solutions were excluded from the combination because they were biasing the combined clock solutions (clock shifts/outliers) but were kept for the RMS computation.

Starting on 5-Nov-2006 (GPS Week 1400, day 0, MJD 54044) all IGS products, including the IGS combined orbits, are based on the IGS realization of the ITRF2005 reference frame (IGs05). For more information see IGSMAIL #5447. 7. Small rotations were applied to the all AC orbit and ERP values in order to align them to the IGS05. These rotations were estimated in the process of the IGS SINEX combination, performed at NRCan by Remi Ferland, are based on the common stations between the individual AC SINEX solutions and the IGS05.snx SINEX. The estimated 7 transformations, from which only the 3 rotations are applied to the orbit and ERP values, are: | DX DY DZ RX RY RZ SCL Centre | [mm] [mm] [mm] [uas] [uas] [uas] [ppb] -------+--------------------------------------------------- COD | .0 .1 .4 -4 6 -1 -.05 EMR | 8.5 -16.7 5.9 -13 16 12 .27 ESA | 4.7 -2.0 -3.4 -15 -2 -3 -.87 GFZ | .5 -.2 .5 -6 -30 0 -.11 JPL | 6.5 -5.7 22.7 163 -93 165 .51 MIT | 3.7 -2.8 15.4 -18 4 -8 .34 NGS | 5.5 -1.5 6.0 -30 -52 27 -.91 SIO | -.3 -8.0 -9.6 -79 -36 25 .44 8. Starting on 22-Oct-2000 (GPS Week 1085-0; mjd=51839) all IGS clock products are based on the new clock combination scheme which uses the clock RINEX files as input if available, otherwise SP3 clocks are used. The navigation solution is still based on the SP3 clocks but this will soon adopt the clock RINEX files as well. 9. Starting on 27-Feb-2000 (GPS Week 1051-0; MJD 51601) the IGS final products are aligned to the IGS reference frame products (station coordinates and ERPs as generated by NRCan. For more information see IGSMAIL #2750. Because of this change in alignment Table 2 has been enhanced with one additional line per AC. This additional line shows the X- and Y-rotations which were applied to each of the AC orbits prior to the orbit combination. These rotations are based on the difference between the individual AC ERP estimates and the IGS reference frame ERP product. The total rotation of the individual AC orbits w.r.t. the IGS combined orbit is the sum of the values in the two lines of Table 2 plus the reference frame rotation. 10. Starting on 5-Nov-2006 (GPS Week 1400, day 0, MJD 54044) the absolute antenna model is introduced (IGSMAIL #5272). The antenna phase center offsets and phase center variations are given in the file: ftp://igscb.jpl.nasa.gov/pub/station/general/igs05.atx 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 1.1421.a). It also displays the computed satellite position sigmas for the combined orbits (table 1.1421.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 2.1421.[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 3.1421.[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 4.1307). The fifth and final part, Table 5, is similar to Table 4 and contains daily precise navigation statistics (tables 5.1421.0-6). 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.

from long arc orbit dynamics (7-day). The first IGS column gives resulting satellite accuracy measures found in SP3 header. The last IGS column gives the RMS fit of the IGS orbit when processed through the 7-day arc evaluation. "E" stands for eclipsing satellites (earth). "M" stands for eclipsing satellites (moon). "X" stands for excluded from the statistics but included in IGS orbit. "T" stands for Total long arc orbit RMS for all satellites. "NE" stands for long arc orbit RMS for Non-Eclipsing satellites only. "MEDI" stands for median of the centre's satellite RMS. "MD" Units: mm.
