gpsd is a service daemon that monitors one or more GPSes |
2 |
attached to a host computer through serial or USB ports, |
3 |
making all data on the location/course/velocity of the |
4 |
sensors available to be queried on TCP port 2947 of the |
5 |
host computer. With gpsd, multiple GPS client applications |
6 |
(such as navigational and wardriving software) can share |
7 |
access to GPSes without contention or loss of data. Also, |
8 |
gpsd responds to queries with a format that is substantially |
9 |
easier to parse than the NMEA 0183 emitted by most GPSes. |
