22. Data Structure 22.4.6 Satellite Problem File Type: ASCII Directory: ${X}/GEN (UNIX) or %X%\GEN (Windows) Extension: CRX Content: Problems with satellites (maneuvers, bad data). Created by: User-defined. Available from BSW aftp server. DEFXTR (”Menu>Orbits/EOP >Extract orbit generation program output”) for orbit splittings, RESCHK (”Menu>Service >Automated processing>Detect misbehaving stations/satellites”) for bad satellite data. Used by: Most orbit and processing programs. Example: Figure 22.8 and ${X}/GEN/SAT 2004.CRX. Remark: • We recommend to use the updated files (filename characterized by the year) from the anonymous BSWUSER ftp area (http://www.aiub.unibe.ch/download/ BSWUSER50/, see Section 4.12). By specifying this file you avoid many troubles related with problem satellites.

22.4 General Files • The satellite problem file invokes the handling of the following problems: (1) maneuver epochs (problem 0) (2) satellite modeling (problem 4) (3) time intervals with bad phase/code data for specific satellites (problems 1, 2, 3) • The first problem type (problem 0) is used to indicate satellite maneuvers. The processing programs read this file and use the orbit of satellite with number PRN before and PRN+50 after the maneuver epoch. The satellite with number PRN+50 is only present in the orbit files, but not in the observation files. ORBGEN treats the “new” satellite as any other satellite. For maneuvers the action number is always 0. • If the maneuver epoch is accurately determined, the data before and after the maneuver are usable without problems. Only a few observations around the maneuver epoch (a few to several minutes) may have to be deleted using problem type 3 (the residuals of MAUPRP may be used for a refinement of this time interval). • The problem type satellite modeling (problem 4) is used for long-arc computations using program ADDNEQ2 (”Menu>Processing>Normal equation stacking”). This problem type indicates to set up a new arc (action 0) for the specified satellite at the specified time (only NEQ boundaries are allowed). • The problem type bad satellite data (problems 1, 2, 3) is used to exclude data of a particular satellite from the processing. If you specify this file in RXOBV3 (”Menu>RINEX >Import RINEX to Bernese format>Observation files”) you have the possibility to transfer them to the Bernese formats as marked observations (action item 1) or to remove them (action item 2; not transferred to the Bernese-specific format). The remove action is supported only in program RXOBV3. If observations for a satellite are not removed, orbit information has to be available for the processing. • For program CODSPP (”Menu>Processing>Code-based clock synchronization”) the presence of this file means not to use the pseudorange data (problem 2 or 3, action 1) for the estimation of the receiver clock corrections. In some cases the pseudorange observations of a certain satellite are bad, but the corresponding phase observations are good. However, it may be better to mark both, pseudorange and phase observations, to avoid problems in the next processing steps. • Using this file in the program MAUPRP (”Menu>Processing>Phase preprocessing”) means that the phase data are marked (problem 1 or 3, action 1). • If you use the file in the program GPSEST (”Menu>Processing>Parameter estimation”) you exclude the corresponding observations from the parameter estimation automatically. The satellite problem file thus represents an easy way to exclude (and include again) observations of individual satellites from the processing without marking them in the observation files with program SATMRK (”Menu>Service>Bernese observation files>Mark/delete observations”). • The file may be updated by DEFXTR (inserting arc splittings) and RESCHK (adding intervals for bad satellite data).
