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.

Show only Lufthansa aircrafts

This example will connect to a single SBS-1 host and only aircrafts from the German Carrier 'Lufthansa' will be written to stdout. We use a single filter rule to realize this plan. For some filter rules it is required to load the databases! In this example we assign only a filter to the callsign. Therefore the databases must not be loaded. This program will run appr. 5 minutes.
