Using dump1090 in Windows

Dump1090 is a command line based ADS-B decoder for the RTL-SDR. It is considered by many to be the best ADS-B decoder for the RTL-SDR available at the moment. Dump1090 is most commonly used in Linux but over on his blog, SonicGoose has written a tutorial that shows how to use dump1090 on Windows with the popular PlanePlotter software. He also shows how to use ModeSMixer2, which is another command line utility that is used to combine data from multiple ADS-B decoders and then rebroadcast the combined feed.

SonicGoose writes that the reason that many PlanePlotter users are moving away from the simpler GUI based RTL1090 ADS-B decoder is because dump1090 provides better raw data to use for multilateration. Multilateration is a technique supported by PlanePlotter which used data shared from multiple receivers to determine the location of an aircraft, even if that aircraft is not transmitting location information.

ADS-B Decoder dump1090 now Available on Windows

Dump1090 is a popular command line ADS-B decoder which many people believe has superior decoding performance compared to other decoding software. Previously it has only been available for Linux and Mac operating systems, however recently it has been updated with a Windows command line version. The most up to date branch of dump1090 can be downloaded from GitHub here.

To install dump1090 on Windows follow these steps:

  1. Download the dump1090 zip file from the GitHub download link.
  2. Download the official RTL-SDR Windows release from http://sdr.osmocom.org/trac/attachment/wiki/rtl-sdr/RelWithDebInfo.zip.
  3. Copy the libusb-1.0.dll, rtlsdr.dll and pthreadVC2-w32.dll files from the official RTL-SDR Windows release zip file to the dump1090 folder. Rename pthreadVC2-w32.dll to pthreadVC2.dll.
  4. Double click on dump1090.bat.

The batch file starts a dump1090 webserver which can be viewed in any browser by going to http://localhost:8080. You may wish to edit the batch file and add extra flags such as –aggressive and/or –fix to improve decoding.

Update: RTL-SDR Running ADS-B on a Quadrocopter now with Augmented Reality Display

Previously we showed a post on how John Wiseman was able to get ADS-B decoding with dump1090 running on his AR.Drone with an RTL-SDR stick so that he could track the locations of other aircraft. He has now gone further and implemented an Augmented Reality style ADS-B aircraft radar display on his AR.Drone. Check out the video he posted showing it in action below.

Virtual Radar Server running on a Raspberry Pi with Mono

YouTube user 907h9879070g9790 has posted a video showing Virtual Radar Server running on a Raspberry Pi with the Raspian hardfloat image OS installed. He used Mono to allow the .NET based Virtual Radar Server to run on the Raspberry Pi. Instructions for using Virtual Radar Server with Mono can be found here.

Combined with an rtl-sdr and dump1090, ADS-B packets can be sent to Virtual Radar Server, and then the aircraft radar map can be viewed on a PC or internet enabled device via a network connection. This can allow a small self contained remote ADS-B monitoring system to be set up.

EDIT: Unfortunately the video owner has taken down the video.

RTL-SDR Running ADS-B on a Quadrocopter

Blogger John Wiseman has managed to get ADS-B decoding using an rtl-sdr stick working on his AR.Drone quadrocopter. The AR.Drones run on the Linux operating system, so he was able to compile and install the Linux ADS-B decoder dump1090 on his drone.

Although the reception was hampered by RF interference from the drones electric motors, it was still able to pick up a number of ADS-B signals.

RTL-SDR Tutorial: Cheap ADS-B Aircraft RADAR

The RTL-SDR can be used as a super cheap real time air radar. Modern planes use something called an ADS-B (Automatic Dependent Surveillance-Broadcast) Mode-S transponder, which periodically broadcasts location and altitude information to air traffic controllers. The RTL-SDR can be used to listen to these ADS-B signals, which can then be used to create your very own home aircraft radar system. Compared to dedicated commercial ADS-B receivers which can go for between $200 – $1000, the $20 RTL-SDR is very attractive for the hobbyist in terms of price. However, note that the RTL-SDR probably shouldn’t be used for ADS-B navigation in a real aircraft for safety reasons. 

ADS-B broadcasts at a frequency of 1090 MHz. It has been discovered by the RTL-SDR community, that the RTL-SDR with R820T tuner has the best sensitivity at this frequency. The E4000 and other tuners perform poorly in comparison. So it is recommended that you obtain an R820T tuner if you want to set up ADS-B decoding with the RTL-SDR. Recently there has also been talk about the R820T2 tuner, which seems to have slightly better performance too. See the Buy RTL-SDR dongles page for more information on where to purchase.

We also now note that recently new higher end SDR’s like the $199 Airspy have developed very good ADS-B receivers that are several times more sensitive that the RTL-SDR.
