So let me short summarize this
1. conntect GPS device
2. in the config (osmocom.cfg) change the following lines from
.....
!
gps device /dev/ttyACM0
gps baudrate default
no gps enable
!
ms 1
 sim reader
.......
to
....
!
gps device /dev/ttyACM0
gps baudrate default
gps enable
!
ms 1
 sim reader
.....

3. run Cell_log
4. convert Cell_log with gsmmap to a valid .kml file

is this correct ?

You will need one, even for triangulation you will need to some base
coordinates. Please feel encouraged to create a wiki page for the cell_log
application to describe its requirements and features.



Relevant sourcecode to initiate opening the GPS device:
