libhomeradar - easy collect aircraft informations

libhomeradar is an easy to use library for all type of programming language which can use libraries. libhomeradar can connect to different sources to collect aircraft informations arround the world with extended informations, powerful filtering and structured data access.

libhomeradar is written in C and is available for Linux and Windows (2003, XP, NT, Vista).

Currently libhomeradar works with the Kinetic Avionics SBS-1 base station and the Airnav Systems Radarbox.

This short example will demonstrate the data sharing option of libhomeradar.
As known from SBS1 and Radarbox, you can also pickup all contacts over TCP/IP sockets. Since version 1.005 libhomeradar can also enable the data sharing option on port 30003 (can be changed).
You have to decide who can connect and pickup your contacts with a simple IP-based exclusion table.

After start of this example you can start a telnet session to see the shared data:
telnet localhost 3333

Data sharing is not legal in every country. Please check this before you enable this option.
You have to assume total responsibility on the consequences of sharing your aircraft contacts
