HERMES Autonomous Positioning System
The Hermes sensor system provides real-time measurement of an aircraft's location relative to a beacon. The system components, going clockwise from the bottom left, are: a camera, a processor platform, an LED beacon, and an OLLI sensor.
Cargo Pick-up and Delivery
The Hermes sensor and processing electronics find and identify the load. Hermes provides precision guidance to the aircraft and an automatic AOS hook connects to ground equipment that is attached to a load. The aircraft flies to a waypoint and Hermes locates and identifies an optical beacon. With the beacon in sight, Hermes directs the aircraft to precisely deliver the load. (PATENT PENDING)
The Hermes system is a real-time sensor system that measures the location of an LED beacon and its orientation. A camera and an optical communication sensor on the A/C take images of the beacon on the ship and provide those images to the sensor processing electronics, also on the A/C. Using those images, the processor computes the A/C's location relative to the beacon. It also computes the beacon's roll, pitch, and yaw. By placing the beacon on the ship deck, Hermes is thus able to compute the A/C position relative to the ship deck and the deck's motion and angle.
The Hermes system provides the front-end sensing required for any auto-landing or pilot cueing system. It calculates the state vector of the deck in a manner similar to the UAV Common Automatic Recovery System (UCARS), but does so with minimal hardware on the ship, hardware that is smaller than a briefcase.
