Northrop Grumman supplied the fibre-optic, gyro-compassing LCR-100 AHRS for
integration with the Rockwell Collins Pro Line Fusion^® avionics system on the
fly-by-wire Legacy 500 and Legacy 450 aircraft. Certification of the Legacy
500 is planned for early 2014 and will be followed by certification of the
Legacy 450.

Developed by Northrop Grumman LITEF, which is Northrop Grumman's navigation
systems subsidiary in Freiburg, Germany, the LCR-100 AHRS provides navigation
information regarding the aircraft's position, heading and attitude. The
north-finding gyro-compass feature eliminates the need for a magnetic sensing
unit, similar to an inertial reference system. Additionally, the system's
precise inertial measurement unit enables extended coasting performance for
the aircraft to continue providing accurate navigation information in the
event of GPS signal loss.

"The gyro-compassing LCR-100 performed flawlessly during the successful first
flight of the Embraer Legacy 500, demonstrating its high-performance
capabilities and greater efficiency," said Eckehardt Keip, managing director
for Northrop Grumman LITEF. "Our system supports the precise navigation needed
for required navigation performance airspace, and provides a totally
independent source of critical flight information in case of GPS loss."

Northrop Grumman LITEF is a leading supplier of inertial sensors, inertial
reference, and inertial navigation systems and computers with products
deployed in more than 30 countries in aircraft, marine vessels and ground
mobile applications. The company has more than 15,000 fibre-optic gyro systems
serving in aircraft worldwide.

Northrop Grumman is a leading global security company providing innovative
systems, products and solutions in unmanned systems, cybersecurity, C4ISR, and
