Abstract

This AN guides the reader through the implementation of an ADS-B/Mode-S receiver using the gr-air-modes Out-of-Tree (OOT) module for GNU Radio. An explanation of ADS-B is also provided, and several real-world, over-the-air examples and profiled.

Overview

The Ettus Research™ USRP™ (Universal Software Radio Peripheral) is used for a number of military and aerospace applications. In this example, the USRP N210 and WBX daughterboard is used to receive and decode ADS-B and Mode-S beacons from real-world aircraft. While a USRP N210/WBX is used for this demonstration, a B200/B210/B200mini/B205mini/E310/E312 or X300/X310 with an appropriate daughter board will work. The information from these beacons is displayed on a Google Earth map. This demonstration shows the flexibility offered by GNU Radio, an open source package and it's strong user-base.

The GNU Radio Out-Of-Tree module (OOT) gr-air-modes will be use to receive ADS-B/Mode-S with the USRP.

Requirements

  • Python >= 2.5
  • PyZMQ
  • NumPy and SciPy
  • SQLite 3.7 or later
  • CMake 2.6 or later
  • Gnuradio >= 3.5.0
  • Ettus UHD >= 3.4.0

Installation

   $ sudo apt-get install sqlite3 libsqlite3-dev python-zmq python-numpy python-scipy
   $ git clone https://github.com/bistromath/gr-air-modes.git
   $ cd gr-air-modes/
   $ mkdir build
   $ cd build
   $ cmake ../
   $ make
   $ sudo make install
   $ sudo ldconfig

Usage

After successfully building and installing the gr-air-modes OOT, you will have two applications to receive Mode-S.

  • modes_rx
    • Command line based, textual output of data received


  • modes_gui
    • GUI based interface with Google Maps integration
