Ashtech B-File
The following describes the options available for this converter:
Ashtech Receiver Type
Selects the receiver used to collect the data. If auto-detect is unsuccessful, then select the receiver manually.
General Options
Perform pre-processing checks
If enabled, data is scanned after conversion to correct potential issues. See Pre-processing Checks for more information.
Detect static/kinematic from site name
Looks in B-file for data tagged as static or kinematic, using ???? site ID.
Verbose messaging mode
Displays additional warning messages.
Extract stations information from Ashtech 'D-File'
Various Thales hand-held controllers output a D-file containing features and antenna height information. Enable this checkbox to utilize this information.
Ignore SBAS Satellites
Newer versions of Ashtech firmware have resulted in the logging of raw data from SBAS satellites, which are not supported by the software. As such, this option should be left enabled to ensure the data is not written to the GPB file.
Static/Kinematic Mode
This option controls how the static/kinematic flags are set in the final GPB file. Auto will set the entire file static or kinematic according to the detected processing environment.
UTC Options
Use the following UTC time
Changes the GPS to UTC time offset from the current nominal value to a user-defined value. Normally used for GLONASS processing if no UTC is contained in the data.
Correct GPS time in D-FILE for UTC offset
D-files can have GPS or UTC time. This option changes time from UTC to GPS.
Dfile Options
Chain Repeated Station Marks into 1 Static Session
Combines sessions that are repeated in the Seismark software into one session.
Do NOT Chain Marks that are more than n seconds apart
This value controls the time tolerance used in the previous setting. If two static periods are marked less than the amount apart, they will be combined.

Thales files follow a strict naming convention. In the table above, ssss is the site name, yy is the last two digits of the year, and jjj is the day of the year.
Antenna heights may need to be edited within the feature editor if not kept constant, as the Thales format only allows for one value.
You might need to select the receiver type manually.
