FISINT

FISINT (Foreign Instrumentation Signals INTelligence) is intelligence from the interception of foreign electromagnetic emissions associated with the testing and operational deployment of foreign aerospace, surface, and subsurface systems.^[1] Since it deals with signals that have communicational content, it is a subset of COMINT, which, in turn, is a subset of SIGINT. Unlike general COMINT signals, the content of FISINT signals is not in human language.

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 from UAVs or from satellites used for reconnaissance.
