**OPTION-3:**  
Jessie Lite image + dump1090-mutability + Piaware data feeder

(1) Insert microSD Card in your Desktop/Laptop’s card slot (or use a card reader plugged into USB Port).  
(2) Format microSD Card.  
(3) Download Jessie Lite image (zip) on your Desktop/Laptop and unzip downloaded file.  
(4) Write the unzipped Jessie Lite image to microSD Card.  
5) After image is written, and microSD card is still in card reader of Desktop/Laptop, (a) Enable ssh (b) Configure WiFi

**(a) To enable SSH:**

**Windows:**  
In File Explorer, double click the drive letter of microSD card. This will open the folder /boot and show lots of files and some folders. Right click in /boot folder, and create a new blank file named ssh or ssh.txt

**Mac:** Open terminal and give following command  
$ touch /Volumes/boot/ssh

**(b) To enable Wifi on first boot (if required):**

**Windows:**  
In File Explorer, double click the drive letter of microSD card. This will open the folder /boot and show lots of files and some folders. Right click in /boot folder and create a new blank file named wpa\_supplicant.conf. If your Desktop/Laptop does not show file extensions, configure Windows File explorer to show file extensions. If the file has a hidden extension .txt, it will not enable wifi.

Alternatively you can create this file by giving following command in Windows command prompt console, which will create file with correct extension:  
C:\Windows\System32\>echo \> M:\wpa\_supplicant.conf  
(Replace letter M by drive letter of your microSD Card in Windows)

**Mac:** Open terminal and give following command  
$ touch /Volumes/boot/wpa\_supplicant.conf  
Open the Finder program. Select the Micro SD card device labeled piaware. Open the file “wpa\_supplicant.conf” in TextEdit.

**Windows & Mac:** In the opened blank file wpa\_supplicant.conf, copy paste following text:

```auto

network={
    ssid="YOUR_SSID"
    psk="YOUR_PASSWORD"
}

```

Replace YOUR\_SSID by your router’s wifi ssid, and YOUR\_PASSWORD by your router’s wifi password.  
Save file. On boot, wifi login info will be automatically copied into file /etc/wpa\_supplicant/wpa\_supplicant.conf, enabling wifi on first boot.

**(6) Remove microSD card from card reader, insert into Pi, power up, and SSH.**

**(7) Install dump1090-mutability v1.15~dev**

**Below is a step-by-step method to built & install dump1090-mutability\_1.15~dev from source code, and then steps to install data feeders FR24, FA, and PF.**

[list]  
STEP-1: UPDATE THE OPERATING SYSTEM

```auto

sudo apt-get update

```

STEP-2: INSTALL PRE REQUISIT PACKAGES (needed to build, and needed to fulfill dependencies)

```auto

sudo apt-get install -y git
sudo apt-get install -y build-essential
sudo apt-get install -y debhelper
sudo apt-get install -y rtl-sdr
sudo apt-get install -y librtlsdr-dev
sudo apt-get install -y libusb-1.0-0-dev
sudo apt-get install -y pkg-config
sudo apt-get install -y fakeroot
sudo apt-get install -y curl
sudo apt-get install -y cron
sudo apt-get install -y lighttpd

```

STEP-3: DOWNLOAD / CLONE THE SOURCE FILES TO YOUR RPi

```auto

cd ~/
sudo mkdir install-dump
cd install-dump
sudo git clone https://github.com/mutability/dump1090.git

```

STEP-4: BUILD THE DUMP1090-MUTABILITY PACKAGE  
Note: This is a lengthy process, and seems to freez at several occasions. Please be patient, and let the process take it’s time to finish.

```auto

cd ~/install-dump/dump1090
sudo dpkg-buildpackage -b

```

STEP-5: INSTALL THE DUMP1090-MUTABILITY PACKAGE

```auto

cd ~/install-dump
sudo dpkg -i dump1090-mutability_1.15~dev_*.deb

```

STEP-6: CONFIGURE THE WEB SERVER

```auto

sudo lighty-enable-mod dump1090
sudo systemctl force-reload lighttpd

```

STEP-7: DUMP1090-MUTABILITY POST INSTALLATION CONFIGURATION

```auto

sudo dpkg-reconfigure dump1090-mutability

```

For most settings, accept default settings by pressing “Enter”.  
For following settings, enter values as shown:  
(a) RTL-SDR dongle to use: 0  
(b) Your receiver’s Latitude (in decimal format): xx.xxxx  
(c) Your receiver’s Longitude (in decimal format): yy.yyyy  
(d) Interface address to bind to (blank for all interfaces): remove default 127.0.0.1 and leave blank.

For advance users:Alternatively, you can change the settings by editing the configuration file shown below:

```auto

sudo nano /etc/default/dump1090-mutability
#after making changes, save file and exit 
#restart dump1090-mutability
sudo systemctl restart dump1090-mutability

```

**(8) Install Piaware 3.5 data feeder (add-on package install)**

```auto

wget http://flightaware.com/adsb/piaware/files/packages/pool/piaware/p/piaware-support/piaware-repository_3.5.1_all.deb
sudo dpkg -i piaware-repository_3.5.1_all.deb
sudo apt-get update

sudo apt-get install piaware

sudo piaware-config allow-auto-updates yes
sudo piaware-config allow-manual-updates yes

#now restart piaware
sudo systemctl restart piaware

```

**(9) For retaining existing station number and it’s stats**

First find and note down existing station’s “Unique Identifier” which is in the format “xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx”. You can find it from any of these three places:

Easiest method, from your stats page: [flightaware.com/adsb/stats/user/yourusername](https://flightaware.com/adsb/stats/user/yourusername)  
Before re-imaging, from Pi: cat /var/log/piaware.log  
Before re-imaging, from Pi: cat /var/cache/piaware/feeder\_id

Once you have “Unique Identifier”, give following command after booting and SSH,

```auto

#delete the "Unique Identifier" in cache (which was assigned automatically at boot)
sudo rm /var/cache/piaware/feeder_id

#assign existing "Unique Identifier" by piaware-config command below
# replace “12345678-1234-1234-1234-123456789abc” by Unique Identifier of your existing station

sudo piaware-config feeder-id 12345678-1234-1234-1234-123456789abc 

#Restart piaware 
sudo systemctl restart piaware

```

**(10) For a new station, claim your Pi by logging in to your account and go to page:**  
[flightaware.com/adsb/piaware/claim](https://flightaware.com/adsb/piaware/claim)

**11) ADD TERRAIN LIMIT RINGS (OPTIONAL)**  
Dump1090-mutability v1.15~dev can display terrain limit rings using data obtained from the website [http://www.heywhatsthat.com](http://www.heywhatsthat.com).

(a) First you have to generate a panorama for your location. To do this, follow the steps in first post of the following thread:  
[**What is the Maximum Range I can Get?**](https://discussions.flightaware.com/t/what-is-the-maximum-range-i-can-get/17248)

(b) Once your panorama is generated, look near the top left of your newly created panorama page. You will see URL of your panorama there. The URL will be _http: // www . heywhatsthat . com/?view=XXXXXXXX_ where XXXXXXXX is the ID for your panorama.

See screenshot below.

![](https://us1.discourse-cdn.com/flex019/uploads/flightaware/original/3X/b/4/b4a6d9537fc21a55f5e6461f30589c96d46cc079.jpeg)

(c) Use following command to download the generated panorama’s JSON file “upintheair.json” to your RPi, and save it in the folder “/usr/share/dump1090-mutability/html” (replace XXXXXXXX in the command below by your panorama’s ID).

```auto

sudo wget -O /usr/share/dump1090-mutability/html/upintheair.json "http://www.heywhatsthat.com/api/upintheair.json?id=XXXXXXXX&refraction=0.25&alts=3048,12192"

```

You can create as many rings as you want by adding elevations (in meters) at the end of URL given in the wget command above after “&alts=”, separated by commas.

10,000 ft = 3048 m  
20,000 ft = 6096 m  
25,000 ft = 7620 m  
30,000 ft = 9144 m  
40,000 ft = 12192 m

Hence if you want to add all the 5 elevation rings noted above, the string at the end of wget URL will become “&alts=3048,6096,7620,9144,12192”

To keep map un-cluttered, I have used only 2 rings in the wget command above. i.e. the 10,000 feet (3048 meters), and 40,000 feet (12192 meters).  
Important:  
Use altitude in meters in the wget URL above.  
Do NOT use feet.

(d) RESTART dump1090-mutability

```auto

sudo systemctl restart dump1090-mutability

```
