jika anda guna V4,
- Purge the previous driver:
sudo apt purge ^librtlsdr
sudo rm -rvf /usr/lib/librtlsdr* /usr/include/rtl-sdr* /usr/local/lib/librtlsdr* /usr/local/include/rtl-sdr* /usr/local/include/rtl_* /usr/local/bin/rtl_*
- Install the RTL-SDR Blog drivers:
sudo apt-get install libusb-1.0-0-dev git cmake pkg-config
git clone https://github.com/rtlsdrblog/rtl-sdr-blog
cd rtl-sdr-blog
mkdir build
cd build
cmake ../ -DINSTALL_UDEV_RULES=ON
make
sudo make install
sudo cp ../rtl-sdr.rules /etc/udev/rules.d/
sudo ldconfig
- Blacklist the DVB-T TV drivers.
echo 'blacklist dvb_usb_rtl28xxu' | sudo tee --append /etc/modprobe.d/blacklist-dvb_usb_rtl28xxu.conf
- Reboot

Jika keluar error seperti di bawah, Jika jalan elok, skip saja step ni.
pi@raspberrypi:~/rtl-sdr $ rtl_test
Found 1 device(s):

usb_open error -3
Please fix the device permissions, e.g. by installing the udev rules file rtl-sdr.rules
Failed to open rtlsdr device #0.
Maka follow step di bawah:
download dan install udev Rules untuk RTL-SDR
sudo wget -O /etc/udev/rules.d/20-rtlsdr.rules https://raw.githubusercontent.com/osmocom/rtl-sdr/master/rtl-sdr.rules
Reload udev Rules
sudo udevadm control --reload-rules
sudo udevadm trigger
Tambah User anda ke plugdev Group
sudo usermod -aG plugdev $USER
cabut dongle anda dan test semula.

Install RTL-AIS
sudo apt install librtlsdr-dev libpthread-stubs0-dev
jika RPI anda 32 bit, maka
wget https://launchpad.net/~sailoog/+archive/ubuntu/openplotter/+files/rtl-ais_0.4.2-stable_armhf.deb
sudo dpkg -i rtl-ais_0.4.2-stable_armhf.deb
Manakala jika RPI anda 64 bit, maka
wget https://launchpad.net/~sailoog/+archive/ubuntu/openplotter/+files/rtl-ais_0.4.2-stable_arm64.deb
sudo dpkg -i rtl-ais_0.4.2-stable_arm64.deb
TESTING
Cucuk dongle ke raspi dan test,
sudo rtl_ais -R on -n
dan jika sukses, akan muncul paparan seperti di bawah.

----------------------------------------------------------------------------------------------
Untuk nak feed ke aprs.fi kita memerlukan password yang diberikan oleh aprs.fi.
masuk aprs.fi dan terus cari perkataan AIS sites dan klik.
kemudian klik my account, dan copy AIS password dan paste lah dimana2 atau tulis.
AIS JSON - json file ini diperlukan feed data dari ais-dispatcher ke aprs.fi.
Install ais_jason ( akan nampak beberapa error, tapi boleh abaikan)
git clone https://github.com/hsiboy/ais_json.git
pip install libais
pip install termcolor
cd ais_json/
ais_json ini diperlukan run sentiasa, maka
./ais_json.py &
---------------------------------------------------------------------------------------------------------
pada awal tadi, kita kan set pada OUTPUT Dispatcher seperti di bawah,
OUTPUT :
Host 1 = 127.0.0.1
UDP PORT 1 = 5999
jadi untuk membolehkan ais json ini menerima data dari dispatcher, maka kita perlu
ubahnya juga, untuk ubah, masuk ke dalam ais_json.py dan cari line ini:
IP = '127.0.0.1'
PORT = 5000
dan ubah ke
IP = '127.0.0.1'
PORT = 5999
pada awal tadi, kita kan save password ais untuk aprs.fi kan, so masa ni lah
nak guna password tu, untuk ubah, pergi file settings.py
URL='http://aprs.fi/jsonais/post/PASSWORD'
NAME='CALLSIGN'
akan nampak seperti di atas, dan ubah mengikut password dan callsign anda.
URL='http://aprs.fi/jsonais/post/xxxxxxxx'
NAME='9m2zak'
ok siap!!! sila reboot. selepas reboot, buka 2 terminal.
terminal pertama :
cd ais_json/
./ais_json.py &
terminal kedua :
sudo rtl_ais -R on -n
kemudian buka browser :
http://IPADDRESS:8080 (tukar IP anda sendiri)
dan buka aprs.fi dan jika berjaya, kapal akan muncul selepas beberapa minit seperti dibawah.
---------------------------------------------------------------------------------
auto start rtl-ais
Buat bash script untuk rtl-ais dahulu. buka mana-mana word editor
