Goodrich Corporation has initiated the upgrade of the TERPROM® Ground Proximity Warning System (GPWS) for the Eurofighter Typhoon aircraft. The upgrade adds air-to-surface targeting information to the existing TERPROM predictive ground proximity warning system capabilities, and is expected to be incorporated into the future batch enhancement upgrade to the aircraft. The system is being provided by Goodrich’s Sensors and Integrated Systems team, from the Plymouth, UK-based Atlantic Inertial Systems (AIS) business that was acquired by Goodrich in December, 2009.

The upgraded TERPROM will use its terrain database and proprietary ranging functionality to provide the Typhoon’s attack computer with accurate position, height and range data for ground targets selected by the pilot. This data will then be used to refine the firing solution, increasing the accuracy of weapons delivery. The system supports the enhanced ground attack role of the Typhoon and the ongoing desire to reduce collateral damage without the need for additional sensors or weapon enhancements.

Over 5,000 commercial, military and rotary wing aircraft worldwide are fitted with TERPROM, a portable software system that can be hosted in third-party hardware or provided as a complete line replaceable unit.
