Logging on Linux platforms

Using the GPS daemon gpsd is a convienient way to distribute navigation information to many clients. The gpsd package available for Linux systems provides a set of useful tools for test, simulation and even logging of NMEA data.

The following simple navigation setup has proven to work on Ubuntu 12.04. Start the following commands from a shell or a script:

gpsd -G /dev/ttyS0              # start the daemon reading the serial GPS interface. Option -G provides data also to other hosts. <\br>
opencpn                         # start Chartplotter opencpn, setup data source "Network LIBGPS"
gpspipe -r >> my_nmea_data.log  # attach to gpsd and append
# you may attach more clients, even on other hosts in your network:
xgps localhost                    # graphically show satellite coverage

Logging on Windows platform

It is recommendable to install a software com port-splitter, e.g XPort. Then your chartplotter software and your logger software can each acess a dedicated virtual serial com port.
