Retrieved 8 January The source of the state vector and other transmitted information as well as user applications are not considered to be part of the ADS-B system. ADS-B technology provides a more accurate report of an aircraft's position. Although multilink "solves" the issue of heavy airliners working on one frequency vs. Retrieved 16 September Bush which mandated accelerated approval of NextGen. This system will make radar based ATC obsolete, moving the nation to a satellite derived aircraft location system. Source: DOA .

Primary surveillance radar PSR. Pilots who become complacent or overconfident in this system are thus a safety problem, not only for themselves but for other transponder only-aircraft, and glider aircraft without transponder.
Retrieved 22 March A universal access transceiver is a data link intended to serve the majority of the general aviation community.
ADS-B Out broadcasts information about an aircraft through an onboard transmitter to a ground receiver. NextGen will allow the NAS to expand to meet future demand and support the economic viability of the system.

|Retrieved 21 September Retrieved 24 April The completed system will consist of ground station transceivers.
Bearing is measured by the position of the rotating radar antenna when it receives the RF pulses that are reflected from the aircraft skin. A security researcher claimed in that ADS-B has no defence against being interfered with via spoofed ADS-B messages because they were neither encrypted nor authenticated.
to assess the ability of this extension to existing Mode S formats to meet the MASPS. TLAT Objectives and Membership.
Scope of this Report. 2. Overview of ADS-B/Situational Awareness Link Candidates. MHz Extended Squitter. Note: This ITU-R Report was approved in English by the Study Group under the procedure detailed in 1 MHz Mode S extended squitter ( ES).
The industry is seeing products being developed for all price points, low to high, and competitively priced equipment is nearing approval.
Retrieved 17 November To enable an aircraft to send an extended squitter message, the transponder is modified TSO CA  and aircraft position and other status information is routed to the transponder. The system could be compromised by smaller, private aircraft with exclusively belly mounted ADS-B antennas, due to the aircraft hull blocking the signal. APA

|The radiated beam becomes wider as the distance between the antenna and aircraft becomes greater, making the position information less accurate.
