The gpsd service daemon can monitor one or more gps devices connected to a host computer, making all data on the location and movements of the sensors available to be queried on tcp port 2947.

this package provides libgps, a c service library for querying gps devices. it supports both a low-level interface, which communicates directly with the device to which the gps is connected, and a high-level interface, which goes through gpsd and is intended for concurrent use by several applications.
