ADS B

Introduction

From Wikipedia: Automatic dependent surveillance – broadcast (ADS–B) is a surveillance technology in which an aircraft determines its position via satellite navigation and periodically broadcasts it, enabling it to be tracked. The information can be received by air traffic control ground stations as a replacement for secondary radar. It can also be received by other aircraft to provide situational awareness and allow self separation.

ADS–B is "automatic" in that it requires no pilot or external input. It is "dependent" in that it depends on data from the aircraft's navigation system.

Settings

To receive ADS-B you need some materials, for example:

• an antenna to receive 1090Mhz signal like the Flightaware antenna, there is also some good one on ebay
• A RTL-SDR 820T key, for example: rtl-sdr.com
• A computer, a raspberry pi,... under Linux
• rtl-sdr driver
• Dump1090

You only need to set the IP and of your receiver in the FlightAirMap install page. Use the TCP BaseStation output port (30003) or if it's not available RAW output port (30002).

MLAT

If you want to see MLAT from flightaware on FlighAirMap, on the Raspberry PI:

# piaware-config mlat-results-format "ext_basestation,listen,30106"

Then set the piaware ip with port 30106 as a source that you can name MLAT.
