5.3. SBF2 I SMR PROGRAM
5.3 sbf2ismr Program
The
sfb2ismr
program converts a binary SBF fi le containing 50 or 100 Hz raw correlation
and phase data into an ASC II I SMR fi le containing ionospheric scintillation and TEC indices. I n
addition,
sfb2ismr
can also produce an ASC II fi le containing the unprocessed 50 or 100 Hz
raw correlations and phase data.
sfb2ismr
can also be used for TEC calibrations.
sfb2ismr
is a command line tool: both Windows and Linux versions are provided. Typically,
sfb2ismr
is automatically started from RxLogger at the end of each hourly fi le, but it can
also be manually called at any time to get an instant overview of the scintillation indices, or
to reprocess the raw high-rate data.
The output I SMR fi le contains comma-delimited ASC II records for all satellites in view for
every minute. An example of the contents of an I SMR fi le is given below:

The command
sfb2ismr
with the
-h
option prints the help screen, including a de fi nition of
all the fi elds (or columns) in a record:
C:\Program Files (x86)\Septentrio\RxTools\bin>sbf2ismr.exe -h
sbf2ismr is a utility to convert the data in a SBF file into ASCII ionospheric scintillation
monitoring records.
The SBF file needs to contain the following SBF blocks at at least
the specified interval:
IQCorr, 20ms
MeasEpoch, 1s
MeasExtra, 1s
ReceiverStatus, 10s
ChannelStatus,
10s
ReceiverSetup, 10s
SatVisibility, 10s (optional, allows increased resolution of azimuth/elevation)
GPSNav, OnChange
GALNav, OnChange
BDSNav, OnChange
QZSNav, OnChange
Command line options:
sbf2ismr -f InputFile [-o ISMRFile][-p PreviousFile][-x Systems][-c DetFreq]
[-n NoCols][-S][-r RawFile][-g][-b StartEpoch]
[-e EndEpoch][-V][-h]
-f InputFile (mandatory) Name of the input SBF file.
-o ISMRFile Name of the output file containing the ISMR records (see
format below).
This argument is optional.
If not provided, the output file
name is the same as the input file name, with the extension
.ismr being added. See below the format of the ISMR file.
-p PrevFile Name of the previous input file, i.e. name of the SBF file
logged just before input_file.
The last epochs of the
previous file are used to initialize the detrending filters.
If there is no previous file, skip this option or use NA as
PrevFile.
-C TECCalFile Name of the TEC calibration input file (see format below).
