TERPROM selected for A400
Goodrich Corporation has been selected to provide TERPROM terrain-referenced navigation for the Airbus A400M transport aircraft.
The company was selected by Cassidian - an EADS company. The system for the military transport aircraft will be provided by Goodrich's Sensors and Integrated Systems of Plymouth.
TERPROM is a software-based system that compares actual terrain over which the aircraft is flying - using a radar altimeter - with a digital terrain database driven by the aircraft's inertial system. The difference between the two represents an error vector to be applied to the inertial output.
The system is independent of GNSS and claims an accuracy of 15-30 meters. It also can be used for predictive ground collision avoidance, terrain-following, wire and obstacle warning and target ranging.
Goodrich will continue development activities to adapt, integrate and qualify TERPROM on the A400M, beginning in the third quarter 2011.
TERPROM is in use with 14 nations worldwide and equips over 5,000 military aircraft.
