Compare with Figure 5.8. Page 96 AIUB
5.4 Preparation of Precise Orbit Information models implemented in program ORBGEN allow to reconstruct the IGS precise orbits at the 1 cm level. If orbits from the CODE Analysis Center were used this consistency would be even higher because at CODE the same orbit model is used. It has to be noted that in order to assure maximum consistency, the Earth orientation parameters delivered together with the orbit information have to be used. Figure 5.9 shows a slightly lower precision of the fit to a IGS precise orbit if Bulletin A Earth orientation information is used instead of the IGS Earth orientation information. It is absolutely mandatory to use the same Earth orientation information used to generate the tabular orbit resp. the standard orbit in every program where this orbit information is used. The standard orbit together with the Earth orientation information define the orbits in the terrestrial reference frame. For an automated processing the “Summary file” may be specified in panel “ORBGEN 2: Result and Output Files” well suited. It compiles the RMS of the tabular orbit positions in cm for all satellites in one line. Program DEFXTR may be used to extract information from an output file generated by ORBGEN. The summaries contain total number and eclipsing number of satellites, largest fit RMS as well as a compact list of the fit RMS for all satellites. Furthermore, an arc split summary may list satellites with high RMS. See the corresponding on-line help for more details. Program ORBGEN allows to specify a satellite problem file (see Section 22.4.6). Satellite data marked as bad in this file will not be used for the orbital fit. If a satellite is marked as bad for the entire interval its orbit will not be contained in the standard orbit generated by ORBGEN. A satellite for which an orbital maneuver is indicated in the satellite problem file during the time period covered by the orbital fit may appear two times in the standard orbit file (unless the data is removed as bad): (1) with its actual PRN-number. The orbit fits the tabular positions available before the epoch of the maneuver. (2) with the PRN-number PRN’= PRN+50. The orbit fits the tabular positions available after the epoch of the maneuver. Both orbits cover the entire time period contained in the standard orbit. All programs accessing the standard orbit get their information on the maneuver epoch from the satellite problem file and they switch from the first to the second orbit of the satellite for all epochs following the maneuver epoch. It is, therefore, important to use the same satellite problem file throughout all processing steps. The CODE Analysis Center maintains a satellite problem file. The fileSAT yyyy.CRX (where yyyy denotes the 4-digit year) is updated daily and may be downloaded from http://www. aiub.unibe.ch/download/BSWUSER50/GEN. Files from earlier years are available back to 1992. In addition, a file GPS yyyy.CRX is made available since 2003 which excludes all GLONASS satellites. Users which do not want to use GLONASS data but download precise files containing GLONASS information may remove GLONASS information by using this file. Bernese GPS Software Version 5.0 Page 97
