modes_gui: - Gnuradio Mode-S/ADS-B receiver


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 Collision 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 receiver listens to the 1090MHz
downlink channel; interrogation requests at 1030MHz are not received or decoded by this

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 instance) 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

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

ADS-B-equipped aircraft broadcast ("squitter") their position, velocity, 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

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.


An X display, as all user settings as well as displayed data are handled withing the GUI.

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 connection to a data source.)
