Raspberry Pi独立配置ADS-B dump1090模块

先来看一段相关Github仓库README.md文档给出的简介：Dump 1090 is a Mode S decoder specifically designed for RTLSDR devices. The main features are: Robust decoding of weak messages, with mode1090 many users observed improved range compared to other popular decoders. Network support: TCP30003 stream (MSG5...), Raw packets, HTTP. Embedded HTTP server that displays the currently detected aircrafts on Google Map...

简介

使用Raspberry Pi接收ADS-B信号离不开dump1090模块，执行以下脚本即可，当然也可自己输入指令分步执行。

wget http://www.satsignal.eu/raspberry-pi/build-1090.sh
chmod +x build-1090.sh
./build-1090.sh

搭建步骤

build-1090.sh内容如下：

#!/bin/bash
sudo apt-get update
sudo apt-get upgrade
sudo printf 'blacklist dvb_usb_rtl28xxu\nblacklist rtl2832\nblacklist rtl2830' > /etc/modprobe.d/nortl.conf
sudo apt-get install git-core
sudo apt-get install git
sudo apt-get install cmake
sudo apt-get install libusb-1.0-0-dev  
sudo apt-get install build-essential 
git clone git://git.osmocom.org/rtl-sdr.git
cd rtl-sdr
mkdir build
cd build
cmake ../ -DINSTALL_UDEV_RULES=ON
make
sudo make install
sudo ldconfig
cd ~
sudo cp ./rtl-sdr/rtl-sdr.rules /etc/udev/rules.d/
git clone git://github.com/MalcolmRobb/dump1090.git
cd dump1090
make
sudo reboot

执行完后重启RPi，之后ssh登录，先用lsusb看看能不能发现rtl-sdr，然后执行如下命令：

1	rtl_test -t

如果出现下述错误：

Found 1 device(s):
0: Generic RTL2832U
Using device 0: Generic RTL2832U
Kernel driver is active, or device is claimed by second instance of librtlsdr.
In the first case, please either detach or blacklist the kernel module
(dvb_usb_rtl28xxu), or enable automatic detaching at compile time.
usb_claim_interface error -6
Failed to open rtlsdr device #0.

是由于新版Raspbian内核已经集成了rtl-sdr的驱动，但是这个驱动不是我们需要的，所以要把这个驱动放入黑名单，重新安装osmocom的rtl-sdr驱动。

在/etc/modprobe.d目录建立nortl.conf文件。

1	sudo nano nortl.conf

粘贴以下内容：

1
2
3

blacklist dvb_usb_rtl28xxu
blacklist rtl2832
blacklist rtl2830

reboot之后生效。

执行指令下面的命令，可以在终端看dump1090的输出。

1	./dump1090 --interactive

执行如下指令，能在本地的IP 8080端口看到dump1090的输出了（会调用Google Map API）。

1	./dump1090 --interactive --net

开机自启

开机自动启动：

1	sudo nano /etc/init.d/dump1090.sh

粘贴以下内容：

#!/bin/bash

          echo "Error! $PROG is currently running!" 1>&2
          exit 1
      else

          ## Program is running, so stop it
         echo "$PROG is running"
         killall $PROG
         rm -f $PIDFILE
         echo "$PROG stopped"
      else
          ## Program is not running, exit with error.
          echo "Error! $PROG not started!" 1>&2
          exit 1
      fi
}

case "$1" in
      start)
          start
          exit 0
          ;;
          stop)
          stop
          exit 0
      ;;
      reload|restart|force-reload)
          stop
          start
          exit 0
      ;;
      **)
          echo "Usage: $0 {start|stop|reload}" 1>&2
          exit 1
      ;;
esac
exit 0

然后执行

1 2	sudo chmod +x /etc/init.d/dump1090.sh sudo update-rc.d dump1090.sh defaults

reboot之后生效。

如果想停止服务，执行：

1	sudo /etc/init.d/dump1090.sh stop

删除开机启动服务：

1	sudo update-rc.d -f dump1090.sh remove
