Raytheon's High Integrity GPS Guidance Enhanced Receiver (HIGGER) has been praised by DERA (Defence Evaluation & Research Agency) as a programme that illustrates the particularly successful pull through of technology into production. HIGGER, designed and produced by Raytheon Systems Limited at Harlow, has ability to permit large helicopters and VTOL aircraft to land accurately and safely on the landing decks of small ships in rough seas.
The system, based on highly accurate GPS, is able to position the aircraft accurately over the ship with a three dimensional accuracy of better than 30cm in all weather conditions up to sea state six. Other ship sensors predict the vessel's motion. In the next phase of the HIGGER programme this data will be passed to the aircraft so that landing and recovery can be integrated with the auto-pilot function.
