24. The Step from <strong>Version</strong> 4.2 to<br />

<strong>Version</strong> <strong>5.0</strong><br />

If you start to use an existing campaign originally processed with <strong>Version</strong> 4.2 of the <strong>Bernese</strong><br />

<strong>GPS</strong> <strong>Software</strong> with the new <strong>Version</strong> <strong>5.0</strong> you have to be aware that you cannot switch back<br />

to <strong>Version</strong> 4.2 . Note also, that the results from <strong>Version</strong> 4.2 cannot be reproduced one-by-one<br />

with the <strong>Version</strong> <strong>5.0</strong> due to some changes in the analysis models, e.g., solid Earth tides.<br />

24.1 Introduction<br />

The step from <strong>Version</strong> 4.2 to <strong>Version</strong> <strong>5.0</strong> of the <strong>Bernese</strong> <strong>GPS</strong> <strong>Software</strong> represents a major<br />

upgrade. The menu and the BPE have been replaced by new implementations using C++<br />

and Perl. The input panels were completely redesigned and serve now as sole interface<br />

between the user input and the processing programs. The labeling of the input fields was<br />

revised and gained in clarity.<br />

The format for a long list of files has been changed from <strong>Version</strong> 4.2 to <strong>Version</strong> <strong>5.0</strong> . Most of<br />

them can be used without conversion because reading subroutines are backward compatible.<br />

This means on the other hand that files written by <strong>Version</strong> <strong>5.0</strong> cannot be handled by reading<br />

routines of <strong>Version</strong> 4.2 . These are for instance: the <strong>Bernese</strong> observation header files, normal<br />

equation files from ADDNEQ2, standard orbit files, Earth orientation files, troposphere<br />

parameter result files, residual files.<br />

The Windows version is no longer binary compatible with the <strong>Version</strong> 4.2 , because we had<br />

to change the compiler for the generation of the distributed executables. This, of course,<br />

may also be true for the UNIX version, if you changed the compiler. In this case you must<br />

use the binary-to-ASCII converters from <strong>Version</strong> 4.2 and the ASCII-to-binary converters<br />

of <strong>Version</strong> <strong>5.0</strong> to convert these files to a binary format accessible for the current version<br />

of <strong>Bernese</strong> <strong>GPS</strong> <strong>Software</strong>. This is why we urge you not to overwrite <strong>Version</strong> 4.2 with<br />

<strong>Version</strong> <strong>5.0</strong> .<br />

In addition, the location of several files in the campaign directory structure was changed to<br />

improve clarity and usability.<br />

In this chapter we give advice on how to move an existing campaign from <strong>Version</strong> 4.2 to<br />

<strong>Version</strong> <strong>5.0</strong> .<br />
