Northrop Grumman Corporation has been selected by AgustaWestland, a Finmeccanica company, to provide the Attitude Heading Reference System (AHRS) for the Agusta-Bell 412 helicopter fleet operated by Italy's law enforcement agency, the Guardia di Finanza.
The AHRS inertial sensor installation provides aircraft attitude, heading and flight dynamics information to flight deck displays, flight controls, the weather radar antenna platform and other aircraft systems.
Under the contract, valued at 1.4 million euros ($1.8 million), Northrop Grumman Italia will equip the AB-412 helicopters with the LISA-200W AHRS, which will replace the LISA-4000. The LISA-200W can be easily incorporated with minimal impact on existing avionics architecture, making it a superior technical and economical solution.
"The LISA-200W utilizes the latest fibre-optic gyro technology for improved performance and functionality, making it an ideal candidate for aircraft retrofits and upgrades," said Marco Clochiatti, managing director and general manager of Northrop Grumman Italia. "Additionally, our products have already proven their high performance during more than 20 years on the AB-412 platform and this award further strengthens our navigation leadership in international markets."
The LISA-200W is a lightweight, fibre-optic gyroscope-based AHRS that measures pitch, roll, magnetic heading and turn rate of an aircraft. The availability of several digital and analog interfaces, coupled with high maintainability and reliability, make the LISA-200W a popular choice for new platforms and retrofit applications. The system's modular architecture offers greater flexibility to meet a variety of requirements. Advanced features such as a high-speed data refresh rate and output fulfill the stringent requirements of a fly-by-wire quadruple-redundant control system.
The LISA-200W is part of the LISA-200 family of products, which boasts more than 4,000 systems delivered worldwide, including a configuration integrated with an embedded GPS receiver to provide highly accurate navigation functioning.
