"ADS-B is a
surveillance concept whereby a vehicle (airborne or ground) broadcasts its
position, at regular time intervals, for receipt by some application.
ADS-B is an enabling technology for many new applications.
These applications are being developed to improve airborne and airport
safety and capacity. The main
benefit of this technology is that it provides an accurate, low cost way to
gather position information. " from: http://adsb.tc.faa.gov/ADS-B/186-main.htm
Skyaid view: ADS-B is an improved TCAS, using GPS
and multiple vehicle communications, and will be first used by aircargo
companies such as FedEx and UPS
