Re: [Gpsbabel-misc] Converting NMEA to csv

[Sebastian P. L. <sp...@gm...>]

Hello,

I was able to obtain some more info about this file.  I was told that
the instrument that produced these files is an Applanix POS MV, which is
a motion sensor that delivers both position and orientation to sonar
systems.

Thanks for all your help,
Seb
