Gpsd is a daemon acting as a liason between a GPS (GNSS) receiver or
Loran-C receiver and clients.  The receiver is expected to generate
position information as NMEA-0183 sentences or in any of a number of
vendor-specific binary formats.

Gpsd listens on port 2947 for clients requesting position, time,
velocity or altitude information.

Gpsd can take information from the receiver and translate it into
something easier to understand for clients.
