5.2.4 Configuring the post processing options
The SBF fi les themselves do not contain the scintillation indices however, they can be
computed using the
sbf2ismr
conversion program. RxLogger can be con fi gured to
automatically execute
sbf2ismr
on SBF fi les. You can do this by de fi ning a post-processing
action on the ‘ Post Processing ’ tab of the main window of RxLogger. When logging hourly
fi les, as in this example,
sbf2ismr
will be executed every hour.
Refer to Section 5.3 for a detailed description of the
sbf2ismr
conversion program.
Click the Add button to start de fi ning a new post processing action. From there you can
select ISMR Conversion from the drop-down list as shown in Figure 5-6. Then click on ‘ Next ’ .

On the ‘I SMR Parameters ’ page shown in Figure 5-7, you can select the desired phase

You may want to reduce the number of columns in the I SMR fi le if for example, you are only
interested in single-frequency indices. Section 5.3.1 gives more details on how this can be
done.
You can also exclude one or more constellations from the I SMR fi le, even if the data from
satellites from these constellations are contained in the SBF fi le.
Optionally, you can also provide a TEC calibration fi le in order to correct for TEC biases.
Section 5.3.1 provides more details on TEC calibration.
