Comparative study of rtl1090 and adsb#

The two most used ADSB decoders are adsb# and rtl1090. These decoders can be widely used with interface software like adsbscope and virtual radar. And both these decoders work with the nooelec dongle. 

How they look?

The user interface of rtl1090 looks more like some tech from the spy movies, where as adsb# looks more like any other software that runs on windows.

What's under the skin?

rtl1090 decodes the data in binary, where as the adsb# decodes the data in normal form which is decimal.

What ports are used?

adsb# uses port 47806, while rtl1090 uses port 31001 for the data transfer.

How did they perform in tests conducted at HCAK_Labs?

We tried out both these decoders with a bunch of different interface software on a intel i3-3120M with 8 GB RAM. In majority of the tests rtl1090 was analyzed with packet drop issues while adsb# worked flawlessly in most test conditions but it didn't really work well with virtual radar.

   

Virtual Radar: Sharing the an SDR data online

As we discussed in the article  tracking airplanes with SDR we found another cool software which allows you to share the captured data online. Virtual Radar is a hosting interface software i.e it allows us to host the data online. For example we will be using rtl1090 instead of adsb#. The only difference between them is that rtl1090 decodes the data in the form of binary. 

How to?

1. After installing the software, run rtl1090 first with administrator privilege.
2. Now leave rtl1090 running then run virtual radar.
   
3. Now click on tools and then options. After that click on receivers set the format to AVR or Beast RAW feed and the port number to 31001 and click OK.( click on test connection if you want to make sure that everything is working properly)
   
4. Now click on the url which appears above feed status.
   
5. Now to find out more details about the plane select it by clicking on it. 
   
   
   
6. you can used http://127.0.0.1/VirtualRadar/mobile.html,

http://127.0.0.1/VirtualRadar/desktop.html and http://127.0.0.1/VirtualRadar/settings.html as per your requirement.

Note:-

If the software doesn't work you will need to download a few files from the following link.

Deep web:The unseen part of the web..

The deep web is the web which consist of onion sites these sites are a part of the internet yet unable to most users. Onion sites cannot be accessed through your default web browser.This part of the web is often used

by governments, hackers, etc. In other words a perfect area to host stuff which is not legal . To access these sites you would require tor browser.
These sites can be searched using domain search engines like duckduckgo and onion city. These are special search engines which are used to search content of the dark web.

Now you must be thinking that to launch your own drug selling portal. But but but I would like to warn you that some has already tried this foolish idea. It was known as silk road. And they were foolish enough to think that they can never be caught. But soon the authorities banned it even form the deep web.

Scanning frequency band..

To scan a frequency band with an SDR we will need a python tool known as rtlsdr-scanner which is present in the kali-linux-sdr package. This is a simple tool which creates a frequency to levels graph which can be used for statistical analysis. If you are using a version of Kali Linux other than 5.0 you might have to run the command apt-get install kali-linux-sdr to get all the tools of the package.

How to?

1. Open the terminal window and type rtlsdr-scanner and hit enter.
   
2. Now set the start and stop range of the frequency.
   
3. Then click on start to generate the graph.
4. At the end you will get a graph which you can use for analysis.

To find out if you have the sdr pacakge installed you can check for Kali Linux /wireless attacks/Software Defined Radio.
