Inventors: Thornton, Anthony L.;
Assignee: Lockheed Martin Corporation (Bethesda, MD)
Primary Examiner: Carone; Michael J.
Assistant Examiner: Chambers; Troy
Attorney, Agent or Firm:
A system for detecting, identifying and validating the existence of ordinance located atop or buried beneath the ground including at least one aerial platform capable of powered flight, a base station including apparatus for launching, storing, and refueling the at least one aerial platform, the base station further including apparatus for communicating with the aerial platform, and a control station remote from the base station and including apparatus for communicating with the base station such that a human operator at the control station is capable of communicating flight path instructions to the base station to be communicated to each of the aerial platforms. |

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a novel system for detecting, identifying, and confirming the existence of buried ground ordinance, capable of overcoming many of the disadvantages and drawbacks of similar systems known in the art.
Another object of the present invention is to provide a novel system including a plurality of autonomous aerial platforms comprising a propulsion unit, a differential GPS sensor, a flight control system, a communication relay, collision avoidance sensors, and buried or submerged object detection sensors.
Still another object of the present invention is to provide an ordinance detection apparatus which includes autonomous aerial devices and a base station for coordinating activities such as launching, refueling and docking of the aerial devices, and communicating with each and all of the aerial platforms.
Still another object of the present invention is to provide a system for detecting and identifying buried or submerged ordinance including a plurality of aerial platforms bearing ordinance detection apparatus, a base station for directing operations of the aerial platform, such as launch, refueling, and docking, and a command and control center for determining the time and location parameters of the search and identification missions and for coordinating communications between the aerial platforms, the base station and the command and control center.
Other objects, advantages and features of the invention will become more apparent, as will equivalent structures which are intended to be covered herein, with the teaching of the principles of the invention in connection with the disclosure of the preferred embodiments thereof in the specification, claims and drawings in which:
