Collision Avoidance for UAVs Using Simulated ADS -
Automatic Dependent Surveillance - Broadcast (ADS-B) is part of the FAA's Next Generation Air Transportation System (NextGen). NextGen will transition all aircraft in the United States from a radar-based system, which is not suited to handle the high volumes of air traffic of today, to one that is based on the Global Positioning System (GPS). Air traffic controllers currently use radar to track and manage all aircraft currently in the air. Controllers use the data from radar to plan flight paths for aircraft as they fly, take-off from, and land at airports. Transmitting flight path information requires sending information via oral radio transmission to pilots. This current method is antiquated and is not efficient for the large volumes of aircraft currently and the increases in air traffic expected in the future. A controller can only send out one command at a time verbally and must use large buffer zones around aircraft in order to facilitate the time it takes to interpret radar data and to relay that information to pilots.
The NextGen system using ADS-B data will transform this system. Using real-time GPS data, the system will electronically communicate with pilots to give them the best and most efficient flight path. This will decrease the buffer zones necessary around aircraft, allowing a greater number of aircraft to fly in high traffic zones. While GPS has been around for decades, the finalization of ADS-B and NextGen has allowed this new system to begin to be implemented. ADS-B mandates that each and every aircraft be able to transmit its current coordinates, heading, and speed. This data is then able to be received by air traffic controllers or other aircraft flying in the area. In addition to transmitting data, the system also is able to receive ADS-B data from other aircraft in the area. Instead of relying on air traffic controllers to monitor and track all aircraft using radar data, NextGen using ADS-B is able to do this electronically without any input from air traffic controllers or reliance on radar data.
ADS-B also will allow the integration of Unmanned Aircraft Systems (UAS) into the general airspace. The most common UAS is an Unmanned Aerial Vehicle (UAV). This opens up many opportunities for UAVs to be used in a commercial sense. Using ADS-B, both manned aircraft and aircraft using UAS will be able to t...
