.TH "rtl_adsb" 1 "0.5.0" RTL-SDR "User Commands"
  .SH NAME
  rtl_adsb \- a simple ADS-B decoder
  .SH DESCRIPTION
  Uses a re-purposed DVB-T receiver as a software defined
  radio to receive and decode ADS-B data.	Written by Kyle Keen
  and incorporated in the osmocom rtl-sdr project.
  .LP
  Automatic dependent surveillance-broadcast, ADS-B, consists
  of position and other status data transmitted by aircraft
  in support of air traffic control in order to improve safety
  of flight.
  .LP
  Much software is available for the RTL2832. Most of the user-level
  packages rely on the librtlsdr library which comes as part of the
  rtl-sdr codebase. This codebase contains both the library itself and
  also a number of command line tools such as rtl_test, rtl_sdr,
  rtl_tcp, and rtl_fm. These command line tools use the library to test
  for the existence of RTL2832 devices and to perform basic data
  transfer functions to and from the device.
  .LP
  Because most of the RTL2832 devices are connected using USB, the
  librtlsdr library depends on the libusb library to communicate with
  the device.
  .SH USAGE
  With a suitable antenna for receiving the 1090 MHz signal attached
  to the rtl-sdr supported device, this program will output the
  data decoded from that signal.
