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 connect to an SBS1 host and to an RadarBox host. There will be a listener on port 10000 installed on which you can see all decoded messages (telnet localhost 10000).
After 5 minutes you'll see the contact statistics for both hosts and a list of all contacted aircrafts on every host.
In line 88 we disable the dupecheck for the library. Therefore you can have duplicate results in the list of contacted aircrafts.
