+=head2 Plugin C<gps>
+
+The C<gps plugin> connects to gpsd on the host machine.
+The host, port, timeout and pause are configurable.
+
+This is useful if you run an NTP server using a GPS for source and you want to
+monitor it.
+
+Mind your GPS must send $--GSA for having the data reported!
+
+The following elements are collected:

+Number of satellites used for fix (type instance "used") and in view (type
+instance "visible"). 0 means no GPS satellites are visible.
+
+=item B<dilution_of_precision>
+
+Vertical and horizontal dilution (type instance "horizontal" or "vertical").
+It should be between 0 and 3.

+=item B<Timeout> I<Seconds>
+
+Timeout in seconds (default 0.015 sec).
+
+The GPS data stream is fetch by the plugin form the daemon.
+It waits for data to be available, if none arrives it times out 
+and loop for another reading.
+Mind to put a low value gpsd expects value in the micro-seconds area (500 us) since 
+the waiting function is blocking.
+
+This only applies from gpsd release-2.95.
