The Joint Tactical Information Distribution System (JTIDS) provides jam-resistant digital communication of data and voice for command and control, navigation, relative positioning, and identification. JTIDS is a time division multiple access (TDMA) communication system operating at L-band frequencies. It operates over line-of-sight ranges up to 500 nautical miles with automatic relay extension beyond.

The primary function of JTIDS is to distribute tactical information in digital form. JTIDS technology also locates and identifies subscribers with respect to other users.

Spread-spectrum and frequency hopping techniques make JTIDS resistant to jamming and data encryption makes it secure. As a digital system for both data and voice, JTIDS can handle large amounts of data - far more than the communication systems now used for similar purposes.

A JTIDS terminal automatically broadcasts outgoing messages at predesignated, and repeated, intervals. When a terminal is not transmitting, it receives messages sent by other terminals that transmit, in turn, in a prearranged order.
