A small unmanned air vehicle system having autonomous electrical energy
transmission line docking capability and especially usable in military or
other surveillance situations. Transmission line field sensing by the
small unmanned air vehicle is used as an addition to global position
system and other navigation methods and is especially applied to vehicle
docking maneuvers. A plurality of vehicle carried electromagnetic
fields-responsive sensors provides transmission line based signals to the
vehicle guidance system in both far field and near field environments.
Surveillance sensors are included in the vehicle payload. Vehicle battery
charging energy procurement from the transmission line docking is
included. Related commonly assigned patent documents are identified.
