Bernese GPS Software Version 5.0 - Bernese GNSS Software

22. Data Structure
Created by: Each program.
Used by: User and BPE for error handling.
Example: -
Each program and subroutine writes error and warning messages to the error message file.
Alternatively these messages may be routed to the program output file (see Section 22.10.8).
For details on error output handling see Section 18.6.
Errors are indicated with a string “***”, warnings with a string “###”. Usually the occurence
of an error causes the program to interrupt processing.
22.10.10 RINEX Pseudo Graphics
Type: ASCII
Directory: Campaign-specific directory OUT.
Extension: SMC
Content: Pseudo graphics of satellite observations contained in RINEX observation file.
Created by: RNXGRA (”Menu>RINEX>RINEX utilities>Create observation statistics”).
Used by: Useful to identify tracking problems.
Example: Figure 4.5.
The file type has the same extension as the single point positioning file (see Section 22.10.11).
For more information on the content of the RINEX pseudo graphics file see Section 4.2.5.
22.10.11 Single Point Positioning File
Type: ASCII
Directory: Campaign-specific directory OUT.
Extension: SMC, SME
Content: Contains the CODSPP summary of geocentric coordinates (SMC) or of ellipsoidal
coordinates (SME).
Created by: CODSPP (”Menu>Processing>Code-based clock synchronization”).
Used by: May be useful as a history of coordinate estimations using pseudorange observations.
Example: Figure 22.58 (example for a SMC file).
The advantage of the SMC (and SME) files compared to the usual coordinate files (see Section
22.8.5) has to be seen in the circumstance that the rms information is also stored. The
information may be used to check estimated satellite clock corrections, see Section 14.4.
This file type cannot be re-introduced into any other Bernese program, however. If you
specify always the same file in all CODSPP runs, the new results are appended to all previous
results, instead of overwriting the previous results. The maximum number of lines for this
file is 10,000 lines.
Do not write single point positioning files with the same name in parallel CODSPP runs.
The writing between the programs to the same file is not synchronized and may end in files
which does not contain the complete information from all runs.
