AIS and ADSB with BPQ32/LinBPQ
Introduction
The BPQ Web server can now display AIS (ship tracking) and ADSB
(plane tracking) information. This is designed to interface with
programs rtl_ais and dump1090 which use rtl-sdr dongles.
Installation
AIS
Download
https://www.cantab.net/users/john.wiseman/Downloads/Test/aisbits.zip
Copy the html, png and js files to your linbpq/HTML folder
git clone git://git.osmocom.org/rtl-sdr.git
cd rtl-sdr/
mkdir build
cd build
sudo apt-get install libusb-1.0
cmake ../ -DINSTALL_UDEV_RULES=ON -DDETACH_KERNEL_DRIVER=ON
make
sudo make install
sudo ldconfig
ADSB
For ADSB I am using this version of dump1090. Some other versions
seem to write json files of a different format.

Operation
For AIS:
Although rtl_ais has a tcp interface I've found it hangs after
sending the first message. So I wrote a small program UDPtoTCP to
accept UDP from rtl_ais and relay to TCP connections from BPQ. Run
UDPtoTCP on same machine as rtl_ais. It listens for udp on 10110
from rtl_ais and accepts tcp connects on the same port and relays
the messages.
In APRSDIGI section add
TCPHost=IPAddr
TCPPort=10110
In main section of bpq32.cfg add ENABLEAIS
For ADSB:
If you have dump1090 and bpq on the same machine you can use the
json files written by dump1090. If not you have to use the TCP
interface which uses more CPU, especially if you see lots of planes.
In main section of bpq32.cfg add ENABLEADSB
To use the TCP interface add these to APRSDIGI section of bpq32.cfg:
ADSBHost IPAddr
ADSBPort 30003;
Without these it will read plane data
from /dev/shm/adsb/aircraft.json
