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.

Predefined datatypes

Here you'll see all in libhomeradar.h defined datatypes and structs. Main types are LHR_CONTACT and LHR_STATS. All other types will be used for special database lookups only.


libhomeradar datatypes

/* Structure for airport resolver */
typedef struct {
  char *iata;		// IATA code
  char *icao;		// ICAO code
  char *name;		// Airport name

  double LAT, LON;	// GPS coordinates 

/* All airports of a contacted flight */
typedef struct {
