Northrop Grumman Park Air Systems Delivers Next-Generation Data Communication Multimode Digital Radio to ARINC

LONDON, October 31/PRNewswire/ --

Northrop Grumman Corporation (NYSE: NOC) announced that its Europe-based
air space management communications subsidiary, Park Air Systems is supplying
the first of its new generation IP-enabled multimode digital radios (MDR) to
ARINC. A significant number of production units will be delivered to the data
service provider's Annapolis, Md. headquarters for installation within its
global network. ARINC provides communications, engineering and integration
solutions for commercial, defence and government customers worldwide.

"For more than 10 years Park Air Systems has been delivering
safety-critical digital waveforms within its products and is undoubtedly
the sector's technology leader in implementing this capability," said Charles
Houseago, managing director of Northrop Grumman Park Air Systems. "Due to the
widespread and growing equipage of VDL Mode 2, it is the ideal data link
choice for the FAA's next generation data communications programme, and Park
Air Systems stands ready to support this important initiative with our
innovative products."

Named the PAE 6525 MDR, the software-defined radio delivers data and
voice services in the VHF air band; waveforms included in the 6525 MDR are
aircraft communications addressing and reporting system (ACARS), VHF digital
link (VDL) Mode 2 and AM voice. The implementation of the TCP/IP interface
allows the 6525 MDR to deliver reliable data-link services whilst realising
the cost and performance benefit of modern telecommunication networks.

Park Air Systems commenced its VDL development programme in the early
1990s as the International Civil Aviation Organisation (ICAO) standards were
evolving and has contributed to the evolution of the specifications in both
the USA and European forums. Park Air Systems secured its first contract to
deliver VDL radios to ARINC in 1997, since this time, more than 1000 units
have been deployed globally; in 2001, Park Air Systems was selected as the
technology provider for the FAA MDR programme. This multimode radio
technology today delivers VHF services throughout the National Airspace
System.

ACARS is a legacy data-link system that is still used by many airlines
around the world. VDL provides more efficient communication than ACARS and is
based upon the standards developed and published by ICAO for the
communication of digitized voice and data to and from aircraft. VDL Mode 2 is
a dedicated data link service that can provide both air traffic control
services and airline operational communications.
