Flip a $20 USB stick right into a real-time flight tracker! ✈️ Decode ADS-B indicators to see velocity, altitude, and flight paths of planes above your own home. Construct your individual personal FlightRadar24 as we speak with this straightforward information. 📡

Received a $20 burning a gap in your pocket this Christmas? Flip it into your individual flight tracker. One low cost USB dongle receives plane broadcasts and shows them on a stay map, no subscriptions, no cloud companies, simply planes overhead with their flight numbers, altitudes, and speeds displaying in real-time.
{Hardware} Necessities
RTL-SDR USB dongle with R820T2/RTL2832U chipset. The blue one from AliExpress works completely:
💡
The antenna must see the sky! Place the magnetic antenna exterior a window or on a steel floor for greatest outcomes
The Software program (All Free):
- Zadig (USB driver installer)
- dump1090 (decodes ADS-B indicators from planes)
- Digital Radar Server (shows planes on map)
What ADS-B Truly Is
Industrial plane broadcast their GPS place, altitude, velocity, and identification on 1090 MHz. It is known as ADS-B (Computerized Dependent Surveillance-Broadcast). Your $20 dongle picks up these transmissions. Software program decodes them. You see planes on a map. No particular permissions wanted, these are public broadcasts.
Home windows Setup
Step 1: Set up USB Driver
Home windows does not acknowledge the RTL-SDR with out a generic USB driver.

- Go to zadig.akeo.ie and obtain it, run the .exe file.
- Plug in your RTL-SDR dongle and await Home windows to complete detecting it (even when it fails).
- Proper-click zadig.exe → “Run as administrator”
- Click on
Choices→ TestChecklist All Units - In dropdown, choose
Bulk-In, Interface (Interface 0) - Crucial: Should say Interface 0 (not Interface 1)
- Proper-side field ought to present
WinUSB - Click on
Set up DriverorChange Driver - Look ahead to
The driving force was put in efficiently.
Step 2: Obtain & Run dump1090
- Get the Home windows construct:
github.com/gvanem/Dump1090/archive/refs/heads/main.zip - Extract the ZIP: Unzip to a easy location like
C:dump1090 - Open the dump1090 folder Navigate to the place you extracted it (like
C:dump1090) - Within the folder tackle bar, sort
cmdand press Enter. Command Immediate opens in that location. - Begin dump1090:
dump1090.exe --interactive --net
You will see textual content displaying plane detections. Every line is a decoded ADS-B message. Depart this window open.

Step 4: Set up Digital Radar Server
- Obtain VRS: Go to virtualradarserver.co.uk and obtain the installer.
- Run the installer: Click on by the setup. Default choices work nice.
- After set up, open VRS.
Step 5: Configure VRS to Learn dump1090
Open Digital Radar Server: then from the highest menu click on Instruments → Choices
- Click on
Receiverswithin the left sidebar. - Click on
Wizardto begin the receiver setup wizard. - When requested
what sort of receiver you need to join, selectSoftware program Outlined Radio (SDR). - When requested
which decoder program you might be utilizing with the SDR, choosedump1090. - When requested
Is the decoder working on this laptop?, chooseSure. - End the wizard.
After the wizard completes, click on Take a look at Connection. It ought to say: A connection may be made with these settings.
💡
Allow the receiver: Be certain the checkbox subsequent to your receiver is checked. Click on OK to shut Choices.
💡
Generally through the wizard setup, dump1090 might give up. If that occurs, restart dump1090
Step 6: See Planes
Open the online interface: click on on the blue hyperlink proven in the course of the Digital Radar Server window (for instance: http://127.0.0.1/VirtualRadar).

Your browser will open to a map. Inside a number of seconds, airplane icons ought to seem if there may be air site visitors close by.

macOS Setup
Step 1: Set up Homebrew and Dependencies
- Set up Homebrew, Open Terminal and run the next command
/bin/bash -c "$(curl -fsSLhttps://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" - Set up required libraries,
brew set up cmake libusb pkg-config
Step 2: Set up dump1090
- Set up dump1090 utilizing Homebrew
brew set up dump1090 - Begin dump1090 with this command
dump1090 --interactive --net
You will see textual content displaying plane detections. Every line is a decoded ADS-B message. Depart this window open.
Step 3: Set up Max Planes
- Set up Max Planes from the Mac App Retailer:
https://apps.apple.com/tr/app/max-planes/id1450483676?mt=12 - After launching the app, on the top-right nook. Click on the dropdown that claims
No Connections, then chooseLocalhost. - As soon as linked, the map will begin to populate with planes, and also you’ll see detailed plane data listed on the left aspect

Understanding the Interface
- ICAO code (distinctive plane ID)
- Flight quantity (airline + flight)
- Plane sort (Boeing 737, Airbus A320, and many others.)
- Altitude in toes
- Velocity in knots
- Heading in levels
- Final seen timestamp
What Else Can This Dongle Do?
Your RTL-SDR receives 24-1700 MHz. In addition to planes:
- Climate satellites – Obtain NOAA satellite tv for pc pictures as they move overhead
- Marine site visitors – Observe ships by way of AIS indicators at 162 MHz
- Air site visitors management – Take heed to tower communications (118-137 MHz AM)
- FM radio – Sure, boring, nevertheless it works
- Climate stations – Decode native climate broadcasts
- Pagers – In areas nonetheless utilizing POCSAG
However watching planes by no means will get outdated. Seeing a 787 at 40,000 toes with its precise vacation spot and velocity is persistently fascinating.
Conclusion
RTL-SDR dongles show that highly effective expertise does not require costly {hardware}. A $20 USB stick, free software program, and ten minutes of setup provide you with a pleasant plane monitoring functionality. The broadcasts are already there, planes transmitting their positions 24/7. Your dongle simply listens.
Most individuals by no means understand how a lot information flows by the air round them. ADS-B is one instance. Climate satellite tv for pc transmissions, ship monitoring, digital voice communications, all accessible with the identical {hardware}.
Welcome to the passion. The planes by no means cease flying.
