DESCRIPTION
       A Qt Graphical User Interface to display positions and status  messages
       of aircraft as reported on 1090 MHz.

       gr-air-modes  implements  a  software-defined radio receiver for Mode S
       transponder signals, including ADS-B reports from equipped aircraft.

       Mode S is the transponder protocol used in modern commercial  aircraft.
       A  Mode  S-equipped  aircraft  replies to radar interrogation by either
       ground radar (secondary surveillance) or other aircraft ("Traffic  Col-
       lision Avoidance System", or TCAS). The protocol is an extended version
       of the Mode A/C protocol used in transponders since the 1940s.  Mode  S
       reports  include a unique airframe identifier (referred to as the "ICAO
       number") and altitude (to facilitate  separation  control).   This  re-
       ceiver  listens to the 1090MHz downlink channel; interrogation requests
       at 1030MHz are not received or decoded by this program.

       Automatic Dependent Surveillance-Broadcast (ADS-B) is  a  communication
       protocol using the Extended Squitter capability of the Mode S transport
       layer. There are other implementations (VDL Mode 2  and  UAT,  for  in-
       stance)  but  Mode S remains the primary ADS-B transport for commercial
       use. The protocol is:

       * Automatic: it requires no pilot input

       * Dependent: it is dependent on altimeter, GPS, and other aircraft
         instrumentation for information

       * Surveillance: it provides current information about the transmitting
         aircraft

       * Broadcast: it is one-way, broadcast to all receivers within range.

       ADS-B-equipped aircraft broadcast ("squitter") their  position,  veloc-
       ity,  flight  number, and other interesting information to any receiver
       within range of the aircraft. Position reports are typically  generated
       once per second and flight indentification every five seconds.

       Implementation of ADS-B is mandatory in European airspace as well as in
       Australia. North American implementation is  still  voluntary,  with  a
       mandate arriving in 2020 via the FAA's "NextGen" program.

       The  receiver  modes_rx is written for use with Ettus Research USRP de-
       vices, although the "RTLSDR" receivers are also supported via the Osmo-
       com driver. In theory, any receiver which outputs complex samples at at
       least 2Msps should work via the file input or UDP input options, or  by
       means of a Gnuradio interface. Multiple output formats are supported:

       * Raw (or minimally processed) output of packet data

       * Parsed text

       * SQLite database

       * KML for use with Google Earth

       * SBS-1-compatible output for use with e.g. PlanePlotter or Virtual
         Radar Server

       * FlightGear multiplayer interface for real-time display of traffic
         within the simulator

       Most  of  the common ADS-B reports are fully decoded per specification.
       Those that are not are generally ones which are not commonly used.

       Should you receive a large number of reports which result in  "not  im-
       plemented"  or  "No handler" messages, please use the -w option to save
       raw data and forward it to the author. To save time, note that  receiv-
       ing  a  small number of spurious reports is expected; false reports can
       be excluded by looking for multiple  reports  from  the  same  aircraft
       (i.e., the same ICAO 6-digit hexadecimal number).

REQUIRES
       A  GNU Radio supported receiver for RF capable of 2 Mbits/second sample
       rate and tuning to 1090 MHz. (Or captured data file or network  connec-
       tion to a data source.)
