4.15.3 Perform Survey-In for New Location Setup
To achieve precise time information, the GNSS module needs to do a process “survey-in”. This process
can take up to 24 hours to archive best precision. Depending on the antenna placement and view of the
sky, you might not be able to archive certain survey-in precision.
There is also an option to read in stored survey-in values to make the process faster. However, that is
not covered in this document.
It is suggested to start with 50 m precision and 600-second survey in time.
For survey-in, use the ubxtool -t -w 5 -P 29.20 -v 1 -e SURVEYIN,<time_in_sec> ,
<precision_in_mm> command:
# ubxtool -t -w 5 -P 29.20 -v 1 -e SURVEYIN,600,50000 -f
/dev/ttyGNSS_BBFF ubxtool: enable SURVEYIN,600,50000

4.15.4 Check Survey-In Status
You can create a while-loop to tracking survey-in status before going to the next step. The following
ubxtool command can be a major portion to get survey-in status/result (the last line, valid 1 active
0, indicates that survey-in is successful:
#ubxtool -t -w 5 -P 29.20 -v 1 -p TIM-SVIN -f /dev/ttyGNSS_8600
