5.3. SBF2

SMR PROGRAM

-x Systems

Exclude one or more satellite systems from the observation
file. Systems may be G (GPS), R (Glonass), E (Galileo),
S (SBAS), C (BeiDou), J (QZSS), I (IRNSS) or any combination thereof.
For instance -xERSCJI produces a GPS-only observation file.

-c DetFreq

Cutoff frequency of the carrier phase detrending filter
(6th order high pass butterworth).

Units of Hz. Valid values

range from 0.01 to 1.0 Hz, default 0.1Hz.

-n NoCols

Output the first NoCols in the ISMR file and discard the others
(see column format below).

By default, -n62 is assumed.

-S

Do not generate the ISMR file, but still print the status
screen.

-g

When computing TEC, do not correct for satellite inter-frequency
biases, i.e. ignore the group delay corrections transmitted by
the satellites in their navigation message.

-r RawFile

Name of the "raw file" containing the raw data
(carrier phase and correlations) in ASCII format.

This

argument is optional.

If not provided, the raw file is

not created. See below the format of the raw file.

-b StartEpoch

Time of first epoch to parse from the SBF file (in GPS time
scale). Format: yyyy-mm-dd_hh:mm:ss.

-e EndEpoch

Time of last epoch to parse from the SBF file (in GPS time
scale). Format: yyyy-mm-dd_hh:mm:ss.

-as

Do not generate ISMR data, but print TEC calibration values using
the SBAS ionospheric corrections as reference.

-ak

Do not generate ISMR data, but print TEC calibration values using
the Klobuchar ionospheric model as reference.

-s Signal

Select a different signal than the default "sig2" and "sig3"
mentioned below.

Supported options for the Signal argument are:

C2B2a : Use B2a as second BeiDou signal type (default is B2I).
E3E6

: Use E6 as third Galileo signal type (default is E5b).

E3E5

: Use E5AltBOC as third Galileo signal type (default is E5b).

Note that multiple -s options can be provided, e.g. -sC2B2a -sE3E6.

-V :

Display the version of sbf2ismr.

-h :

Display this help screen.

Format of the ISMR output file
------------------------------

Note: The default signals available the ISMR file are as follows.

Other signals can

be selected with the -s option.

"Sig1": L1CA for GPS/GLONASS/SBAS/QZSS, E1 for GALILEO, B1I for BeiDou

and L5 for IRNSS.

"Sig2": L2C for GPS/GLONASS/QZSS, E5a for GALILEO, L5 for SBAS, and B2I

for BeiDou.

"Sig3": L5 for GPS/QZSS, E5b for GALILEO, B3 for BeiDou.
