This program is capable of subscribing to an UDP multicast feed containing (live) radar data in Eurocontrol Asterix format. The received UDP frames are stored in a recording file. A new (raw) Asterix recording file can be created every x minutes. The previously recorded Asterix filename contains date and timestamp. This tool can be used to do continuous 24/7 Asterix multicast recordings.
This program was written in my own free time at home and is available to anyone who wishes to use it within the limits of the license. Always nice to hear if you use it, any feedback much appreciated.
My personal requirements:
- subscribe to a single multicast group address
- listen for multicast UDP frames on a specific UDP port
- write received UDP frames to a binary recording file
- after a specific time period (block time) create a new recording file
- time stamp a recording file with start and stop time
Based on my original Kakofonix program written in C some years ago which used pcap library to capture multiple Asterix multicast radar feeds.
MiniKakofonix is only capable of recording a single multicast UDP stream, for multi radar UDP feed recording Kakofonix is required which can listen to multiple UDP multicast feeds. (This requires a thread pool with a separate thread for each multicast feed)

This program is compiled/build using Eclipse. An ANT build file (build.xml) is included to create an executable jar file.
ASTERIX stands for All Purpose STructured Eurocontrol SuRveillance Information EXchange.
It is an ATM Surveillance Data Binary Messaging Format which allows transmission of harmonised information between any surveillance and automation system. ASTERIX defines the structure of the data to be exchanged over a communication medium, from the encoding of every bit of information up to the organisation of the data within a block of data - without any loss of information during the whole process. ASTERIX is a EUROCONTROL Standard which refers to the Presentation and Application layers (layers six and seven) as defined by the Open Systems Interconnection (OSI) Reference Model (International Standards Organization (ISO) Standard 7498).
Transmission of ASTERIX coded surveillance information can make use of any available communication medium, for instance Wide Area Network (WAN), Local Area Network (LAN), Internet Protocols (IP), etc as those belong to lower layers.
Considering that there is information common to all systems (for instance position, Mode-A Code and Mode-C Code information), ASTERIX specifies minimum requirements at the Application level, so as to ease data exchange between heterogeneous applications. The communication between two different systems (even located in different countries) is thus made possible, based on a core of commonly used surveillance related data, transferred in the same way by the ASTERIX Presentation layer. For the transmission of information related to a specific application, data items are grouped in ASTERIX Categories. Up to 256 categories can be defined. The definition of these categories and their composition is managed by the ASTERIX Maintenance Group (AMG).
