Abstract

A battery-powered runway-based aircraft identification system includes a frangibly mounted image capture and communication subsystem adjacent to an airport runway. A power supply subsystem adjacent to the frangibly mounted image capture and communication subsystem is operably coupled to the frangibly mounted image capture and communication subsystem and configured to controllably supply electrical power to the frangibly mounted image capture and communication subsystem. The power supply subsystem includes at least one frangibly mounted solar panel operably coupled to a deep cycle battery and charge controller. A remote base station configured for wireless communication with the frangibly mounted image capture and communication subsystem monitors charge status of the battery and determines an aircraft identification from the frangibly mounted image capture and communication subsystem.
