"New System Makes Air-Traffic Control Cheaper and Safer" (Wall Street Journal) reports:
Nav Canada, the privatized provider of air-traffic-control service in Canada, has installed five ADS-B ground-station receivers around Hudson Bay, a vast, remote expanse of northern Canada that is busy with jet traffic but has no radar coverage. The system will go into daily use in January after extensive testing and certification.
As I discussed in GPS for Air Traffic Control, ADS-B is the Automatic Dependent Surveillance-Broadcast system, which tracks airplanes' positions using satellite rather than radar. When widely deployed by airports and used by airlines, ADS-B "has the potential to save fuel, shave time off long flights and enhance safety."
It occurs to me that ADS-B is a good example of the sorts of Technology for a Smarter Planet (More Smarter Planet Info) that IBM has started talking about. It's a way to take something we already do and need and use technology to make it much more efficient such that it saves energy and causes less harm to the environment.
(Separately, the Wall Street Journal also reports that Metallica: Back on Track. I guess they cover a wide range of news topics!)
