1. A method of controlling geofences for a mobile platform, the method comprising the steps of:

  • establishing at least a first geofence for indicating a limit in territorial extent of a permitted operational area for a mobile platform;

    establishing a second geofence for limiting the territorial extent of a permitted operational area for the mobile platform; and

    locating the first and second geofences relative to the permitted operational area so that with movement of the mobile platform through the limits of the permitted operational area from the permitted operational area, the mobile platform encounters the first geofence no later than it encounters the second geofence and the first and second geofences are not fully coincident.
