Joint Tactical Information Distribution System

Joint Tactical Information Distribution System ( JTIDS ) is a military radio system according to the time division multiple access ( TDMA) in the frequency range 890 - 1215 MHz can work.


Originally developed for the armed forces of the United States, today the system is inter alia used in the general area of ​​the NATO air defense. It operates in the frequency range 960 - 1215 MHz, which is allocated in accordance with the Radio Regulation aeronautical radionavigation service worldwide as primary users. Moreover, this frequency range is reserved on a worldwide basis to the use and development of electronic aids to air navigation on board of aircraft and the use and development of related facilities on board. Therefore, the overall system JTIDS / MIDS in NATO Europe has only one frequency availability with restrictions and conditions.

Development since 1970

The development of the JTIDS began in the mid -1970s to replace the tactical Datenliks Link 4 ( Fighter Data Link) by means of a multi-function radios using the Tactical Data Link 16 with the following functions:

  • Data radio
  • Digital voice transmission
  • Secure identification
  • Integration of TACAN

The Tactical Data Link 16 are (in short: STANAG ) according Standardization Agreement 5516 transferred. Another system used in NATO Link 16 the process is, the Multifunctional Information Distribution System (short: MIDS ).

JTIDS and MIDS are largely technically compatible, so they are often also used as a term synonymous.
