DUMP1090-FA
The method for dump1090-fa is different because:
- File
/etc/init.d/dump1090-fa does not exist
- File
/etc/default/dump1090-fa is in a different format. Further, in the Piaware image, it is over-written by piaware-config at restart of piaware or reboot of Pi.
In view of above, following method is adopted to run second Dongle with 2nd instance of dump1090-fa.
DETAILED PROCEDURE
STEP-1: Serialize Dongles
Serialize two dongles (DVB-T / ProStick), one serial number 00000000, other serial number 00000001
Stop dump1090-mutability.
Plug in one Dongle into Pi, serialize it, and put sticker of serial number.
Unplug first dongle, plugin 2nd dongle and serialize it, and put sticker of serial number.
How to Change Serial Number of Dongle - ADSB 1090 + UAT 978 Dongles Plugged Into Same Pi
STEP-2: Create 2nd instance of dump1090-fa which will use 2nd Dongle.
(1) Create a blank file /etc/init.d/dump1090-fa-2
sudo touch /etc/init.d/dump1090-fa-2
(2) Make new file executable
sudo chmod +x /etc/init.d/dump1090-fa-2
(3) Open newly created blank file to edit
sudo nano /etc/init.d/dump1090-fa-2
(4) Copy-paste following code in new blank file

(9) The file /etc/default/dump1090-fa-2 is configuration file for dump1090-fa-2.
Add your required Gain, Latitude and Longitude in it in following lines:
# RTLSDR gain in dB.
# If set to "max" the maximum supported gain is used.
# If set to "-10" (the default) the tuner AGC is used to set the gain.

STEP-3: Enable 2 Separate Maps for 2 Dongles.
Map 1 at < IP OF PI >/dump1090-fa/
Map 2 at < IP OF PI >/dump1090-fa-2/
(1) Make a copy of FOLDER /usr/share/dump1090-fa with name /usr/share/dump1090-fa-2. This folder contains folder html which contains all map files.
cd /usr/share
sudo cp -r dump1090-fa dump1090-fa-2
(2) Create new file /etc/lighttpd/conf-available/89-dump1090-fa-2.conf
sudo nano /etc/lighttpd/conf-available/89-dump1090-fa-2.conf
(3) Copy-paste following code in the newly created blank file 89-dump1090-fa-2.conf
# Allows access to the static files that provide the dump1090 map view,
# and also to the dynamically-generated json parts that contain aircraft
# data and are periodically written by the dump1090 daemon.
alias.url += (
"/dump1090-fa-2/data/" => "/run/dump1090-fa-2/",
"/dump1090-fa-2/" => "/usr/share/dump1090-fa-2/html/"
)
# redirect the slash-less URL
url.redirect += (
"^/dump1090-fa-2$" => "/dump1090-fa-2/"
)
.
(4) Save file (Ctrl+o) and close (Ctrl+x)
(5) IMPORTANT : Enable lighttpd module dump1090-fa-2
sudo lighty-enable-mod dump1090-fa-2
sudo /etc/init.d/lighttpd force-reload
(6) REBOOT PI
MAP-1
http:// < IP-OF-PI >/dump1090-fa/
