Proof of concept of low cost HATC - Homemade Air Traffic Control

SMART MAKE HATC - Homemade Air Traffic Control with 4x RTL-SDR (50$)

Below is a simply collection of information on air traffic reception, a link of some software to be used and a proposal for proof of concept hardware system.

Equipment:

-          1x UHF antenna

-          1x AM Loop antenna

-          2x VHF antenna

-          computer or raspberry (Many OS are supported like Windows, Ubuntu, Debian, iOS and others)

Hobby Level Software 

• MultiPSK (restricted to 5 minutes in the non-registered version)
• The most current version of PC-HFDL can be found at the HFDL Yahoo group
• PlanePlotter (Not a decoder but will show aircraft decoded by PC-HFDL)
• Sigmira
• Sorcerer
• Note: It has been recently discussed on the UDXF (at groups.io) that Sorcerer is using an old freq/site list - you may get correct decodes, but not correct site IDs
• ACARSD

Conclusion

After having carried out several tests and tests of some software reported in my online channels I wanted to consolidate a simple but effective idea of building a multiple receiver of air traffic messages.

Many of the software listed in the list support data streaming via web server, ip, tcp, udp, json, mqtt and others that you can connect to different statistical, collecting, viewing on the map and more software.

If you are looking for how to install the Linux software I suggest you to search through my publications the procedures defined "SMART INSTALL" and use them to install the desired software.

SMART INSTALL dumpvdl2 receiver ON WINDOWS WORKSTATION AND VMWARE WITH RTL SDR

dumpvdl2 turns your Realtek RTL2832 based DVB dongle into a Air traffic vdl2 VDL Mode 2 message decoder and protocol analyzer generic data receiver quick and easy installation.

Tools used

• VMware Workstation Player
• GNU Radio Live SDR Environmento
• szpajder/dumpvdl2

Install Requirements

Windows system machine with 4gb of ram and dual core processor, rtl sdr device.


Pre Installation

• Download GNU Radio Live SDR Environment
• Download VMware Workstation Player
• Install VMware Workstation Player
• Start VMware Workstation Player
• Create a new virtual machine , installer disc image file (iso) with GNU Radio Live SDR Environment image
• Open virtual machine
• Download dumpvdl2-master.zip from Link: https://github.com/szpajder/dumpvdl2 or use git

​ 
Installation dumpvdl2

Download dumpvdl2-master.zip from Link: https://github.com/szpajder/dumpvdl2

Unpack the source code and rename directory in dumpvdl2 or 

git clone https://github.com/szpajder/dumpvdl2.git



Open terminal to the top level directory dumpvdl2 and insert command:

cd dumpvdl2

sudo make



Running: 

Default receive mode, attempt to decode all known devices,open terminal insert:

./dumpvdl2 --rtlsdr 0 

Simplest case on RTLSDR dongle - uses RTL device with index 0, sets the tuner gain to 40 dB and tuning correction to 42 ppm, listens to the default VDL2 frequency of 136.975 MHz, outputs to standard output:

./dumpvdl2 --rtlsdr 0 --gain 40 --correction 42

More option:

./dumpvdl2 --help

how to influence or invalidate data acquired from the accelerometer sensor of a smartphone or embedded system using sounds

During several tests it is observed that not all the frequencies emitted influence the data acquired by the accelerometer and are not due to vibrations on the smartphone body as they are sinusoidal.

in the video there could be conversion errors that they do not sync the audio and images correctly ... sorry ...

block, freeze or void data of magnetometer sensor or magnetic field sensor of smartphone or embedded system using a very powerful magnet.

Dangerous! it could break the hardware of your device!

Personally I have observed very strange behaviors, bugs, blocks of various devices where the field is very strong. The OnePlusOne smartphone when approached to a very strong magnetic field in a precise point activates the screen lock.

Do not experiment if you are not aware of the risk!

I do not consider myself responsible for any damage!
