ADS-B Improves Air Traffic Control, Business and Industry Trends Analysis

A new air traffic control system that is generating headlines is the Automatic Dependent Surveillance-Broadcast (ADS-B) which commenced service in Canada in January 2009.  ADS-B uses GPS information to replace radar when tracking planes.  It is more accurate and faster than radar, allowing planes to travel more closely together safely.  Jets flying under ADS-B surveillance need to be only five miles apart under current standards, even in remote places such as the Earth’s poles or over oceans where radar coverage is not possible.  ADS-B expanded in 2009 with additional receivers on the east coast of Canada and Greenland.  In 2010 the Federal Aviation Administration (FAA) issued a final rule mandating ADS-B usage by January 1, 2020.  The project’s cost is an estimated $4.5 billion.  The FAA largely completed coverage of the U.S. through 700 stations by 2014, working through contractor Exelis, Inc.  The next step is for U.S. airlines to install equipment on their planes which will cost billions of dollars.  The airlines have been slow to implement the installation, due to the high cost and concerns that the FAA would continue to hold up its end of the project by establishing policies and procedures and training controllers.  Federal aviation regulators announced plans to exempt a number of U.S. carriers from the 2020 deadline for certain satellite-navigation upgrades.  However, the FAA continues to require airlines to install ADS-B Out, a more powerful technology than the original ADS-B.

NAV CANADA, a private air traffic control service, initially installed five ground station receivers around Hudson Bay in northern Canada which had no radar coverage.  By 1996, the system took control of all Canadian air traffic.  Today, all 41 of Canada’s air traffic towers rely on the computerized system, as do towers in eight other counties including Australia and Dubai.
