FISINT stands for Foreign Instrumentation Signals INTelligence. (JCS Pub 1-02)[1] defines it as "Technical information and intelligence derived from the intercept of foreign electromagnetic emissions associated with the testing and operational deployment of non-US aerospace, surface, and subsurface systems." Since it deals with signals that are not exchanged by humans, it is a subset of ELINT, which, in turn, is a subset of SIGINT.
Typical examples of such communication include:
- Telemetry data (TELINT). Missiles, satellites, and other remotely-monitored devices often transmit streams of data concerning their location, speed, engine status and other metrics.
- Video data links. These may be present in UAVs or from satellites used for reconnaissance.
