A ground-connected power system for an aerial vehicle, wherein the ground-connected power system provides a conductor wire carried above-ground by supports fixed to the ground. The system further provides a current collector extending between an aerial end and a contact end, wherein the aerial end detachably connects to an underside of the aerial vehicle at an elevation above the conductor wire, and wherein the contact end electrically couples with the conductor wire so that a power component physically connected to the aerial vehicle is electrically powered by the conductor wire.

A trailer, in particular a utility trailer, for road vehicles on which an extendable current collector or an electrical contact element for an inverted current collector is placed.

A vehicle guidance system and method includes at least one guidance sensor configured to mount on or adjacent to a pantograph along a lateral width of the pantograph. The pantograph installs on a vehicle and conducts electrical energy from a conductive pathway as the vehicle travels along a route. The vehicle guidance system and method includes a controller that receives one or more sensor signals generated by the at least one guidance sensor and determines a lateral position of the conductive pathway relative to the pantograph based on the one or more sensor signals.
