22.6 Bernese Observation Files
22.6.1 General Remarks
22.6 Bernese Observation Files
The binary observation information used in the Bernese GPS Software is split into two
parts:
• a header file containing all the relevant information to identify and to process the
observations (station, receiver, satellites, etc.).
• an observation file with all the code, phase, or range observations.
The type of file (code/phase, zero/single, range, header/observations) is indicated by the
extension, see Table 22.2. The file format is the same for all types. This separation of
information in two files makes it easier and more efficient to, e.g., update resolved ambiguities,
since in this case only the header files have to be read and written and not all the
observations.
SLR range measurements are converted into binary header and observation files, too, but
only code zero difference files are created. The SLR range measurements are adapted into
the code zero difference binary format.
No examples are supplied for the binary observation and header files. The ASCII image of an
observation file consisting of header and observations contains, however, the full information
of the binary version and will be described in detail below.
There are small differences between the formats of the observation files for the different
versions of the Bernese GPS Software. Compatibility is guaranteed, which means that you
may, e.g., process Version 3.4 observation files with Version 5.0 , but not vice versa.
Program CHGHED (”Menu>Service>Bernese observation files>Change header information”) may be used
to change the content of the header, program SATMRK (”Menu>Service>Bernese observation files
>Mark/delete observations”) may modify observation flags and reset ambiguities.
