The GPS is controlled with the Kismet server config, kismet.conf. For

By specifying gpsreconnect, if gpsd crashes or Kismet otherwises looses

certain broken GPS/GPSd combinations, where the GPS never reports a

The gpsdevice parameter should be set to the proper serial device for

Kismet cannot know the location of a network, it can only know the

Kismet keeps running averages of the network location, however this is8 e8 i7 X: t, t( W
