The leading ADSB Receiver for Android!!

This app enables your device to receive live ADSB data (978 MHz UAT and 1090 MHz ES). All you need is a supported USB dongle and an OTG cable, both available from various sources on the internet for less than $20.-.

Available in the Android store as a free version (which requires the app to be restarted once a certain amount of data has been received) and as an unlimited "Pro" version. No subscription required.

1. Attach a supported USB dongle to your Android device using an OnTheGo (OTG) cable. Make sure your device supports OTG!
   
2. Allow access to the dongle.

You should see packages flowing in quickly, depending on your location. Click on an aircraft in the "Traffic" view to show it on the map, or open the "Map" view directly. Clicking on the text-box after selecting an aircraft on the map will provide additional details.

Do not use any battery-saving modes if you need the app to run in the background.

You're a Drone Pilot and concerned about nearby traffic? Enable traffic monitoring based on range to be alerted of any approaching aircraft.

You can save all data received to local files or forward it to most GDL90 compatible apps (Avare, iFlyGPS, FltPlanGo, DroidEFB, ...). The app can also receive data from external systems in dump1090/dump978 (AVR) format on UDP port 47909.

For example, if you have Avare or AvareX installed, use this app to forward live ADSB data (traffic and weather) as follows:

• In Avare ADSB
  • Enable "GDL90"
    (you do not need to enable the "Destination" option)
• In AvareX
  • No configuration needed.
    Please note that AvareX limits the visibility of ADSB data by default. It will only show traffic within 2000ft vertically and within 10nm horizontally of your own position.
• In Avare
  • Enable "Use ADSB Weather"
  • Open the "IO" tab and select "WiFi" at the top
  • Set port to 4000 and enable "Listen"

You need:

1. RTL SDR based USB dongle with Antenna
2. OTG cable or adapter

Example dongles:

• NooElec NESDR Nano 2
• NooElec NSEDR Nano 2 ADSB Bundle
• NooElec NESDR Mini 2+
• NooElec NESDR Mini SDR

Antennas - better performance compared to the stock versions:

• ADS-B Discovery Antenna Bundle - 5dBi (High Gain)

Example OTG adapters/cables:

• JSAUX USB-C to USB 3.0 OTG Adapter
• 90 Degree Left Angled microUSB 2.0 OTG Host Adapter (This adapter will allow you to provide power to the dongle, to avoid using the battery of your Android device)
  

List of supported and recommended tuners:

• Rafael Micro R820T
• Rafael Micro R820T2 (R860)

Not recommended or not supported: 

• Elonics E4000 (will almost never work)
• Fitipower FC0013 (very low performance)
• Fitipower FC0012
  

• Does this app require an active internet connection?
  • No, all ADSB data is received over the air. It is in fact recommended to disable all network communications (enable flight mode) to save battery power. However, if you are using the internal Map, you will require an active internet connection.
• Does this app work everywhere?
  • Yes, Avare ADSB works globally.
    The free Avare or AvareX apps provide FAA aviation materials for the United States and other maps for most of the world.
• Is it required to "root" the Android device for this app?
  • No.
• I see data coming in on the "Data" screen, but the map is still empty?
  • Just wait a bit longer. Various single frames need to be received, in order to display the data on the map.
  Does this app work from the "ground"
  • Yes. You will receive 1090 MHz ES (Traffic) very easy but 978 MHz UAT (Traffic / Weather) reception can be limited.
• Will this app keep receiving data while the device is in sleep mode?
  • This depends on the device and the related Android configuration. Some devices will continue (e.g. Samsung Galaxy S3), some not (e.g. Asus TF300T).
• I cannot open the map or other windows in the app, what may cause this?
  • Verify if you have "Don't keep Activities" enabled in the Developer Options, or are limiting Android Activities in any other way.

• Option to configure which aircraft to display in Traffic view (search/sorting)
• Audio alert if a specific aircraft is showing up or getting within a certain range
