When Global Positioning System (GPS) technology was launched, it was
heralded as the next big thing. Although its usefulness has not been quite as
explosive in the consumer market as many people predicted it would be,
GPS has proved useful in areas, such as satellite navigation systems and
mapping tools. Although many people think only ramblers and walkers use
GPS, the technology actually is useful in numerous applications, many of
which you can perform from your Linux desktop. This hack shows you how
you can hook up a GPS unit to your Linux desktop and use some open
source tools to help map out your area.
Connect the GPS to Linux
A number of GPS units are compatible with Linux, and all of them come
with either serial or USB connections. Although two types of connections
are available, the USB connector simply uses a special chip called the FTDI
chip to convert a legacy serial connector to a USB connector. This chip
requires a special driver to convert from a USB to a serial port. A Linux
driver has been developed for this and it is available at http://ftdi-usb-sio.
sourceforge.net/.
Each connector is compatible with Linux, and most of the USB GPS units
include the FTDI driver in the kernel. If you are using one of these USB
devices, you need to ensure ...
