NEWARK - Newark Liberty International Airport will be the first major airport to test new technology aimed at reducing chronic flight delays.

The Ground Based Augmentation System uses global positioning data instead of radar to pinpoint aircraft positions.

Officials hope it will reduce congestion at the airport by allowing planes to fly closer together without compromising safety.

The system, made by Honeywell, will cost the Port Authority of New York and New Jersey - which operates the airport - about $2.5 million.

Continental will spend about $1 million to outfit 15 planes with the satellite navigation, and the FAA is committing up to $2.5 million.

Newark Liberty has been one of the nation's worst airports for departure and arrival delays in recent years.
