ADS-B Operational in Gulf of Mexico

Jan 14, 2010

Houston air traffic controllers are now using Automatic Dependent Surveillance-Broadcast (ADS-B), a GPS-based, NextGen technology, to separate and monitor aircraft flying over the Gulf of Mexico.

That milestone, announced Tuesday by FAA Administrator Randy Babbitt, came as the U.S. Coast Guard prepared to shut down the U.S. Loran-C chains that for decades provided long-range position-fixing capability to mariners and aviators.

“This is a significant, early step toward NextGen,” said Babbitt at the Houston Air Route Traffic Control Center. “We’re delivering on time a system that’s not only more accurate than radar but comes with significant safety and efficiency benefits. This will save time and money for aircraft operators and passengers and reduce our carbon footprint.”

Previously, there was virtually no radar coverage over the Gulf, which required 120-mile in-trail separation of high-altitude IFR traffic.

Similarly, individual helicopters flying under IFR at low altitudes to and from oil platforms were encased in 20x20-mile “boxes” to ensure safe separation from other helicopters. ADS-B now permits five-mile separation.

ADS-B-equipped aircraft use GPS to determine their position, and broadcast it (the B in ADS-B) to ATC ground stations. The ground stations relay the aircraft identity and position to controllers’ displays where it can be fused with radar data as appropriate.

A network of ground stations was deployed on oil platforms and the surrounding shoreline, under agreements with the Helicopter Association International, oil and natural gas companies and helicopter operators, bringing satellite-based surveillance to an area with almost as much daily air traffic as the northeast corridor.

The FAA says the Gulf of Mexico is the second key site where ADS-B is in use by controllers to separate aircraft. The new technology is also being used by controllers in Louisville, Ky., chosen in part because UPS voluntarily outfitted much of its fleet with ADS-B avionics. Four ground stations give controllers at the Louisville International Airport and the Louisville TRACON an ADS-B coverage area extending 60 nautical miles around the airport up to 10,000 feet.

Controllers in Philadelphia will begin using ADS-B next month and the system will become operational in Juneau in April. ADS-B is expected to be available nationwide by 2013.

Bueno ya era tiempo de que implementaran esta tecnologia, ahora ya veran el progreso del vuelo desde tierra sin depender de las limitadas 200 millas de los radares...saludos...
