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 regular human language, but rather in machine to machine (instrumentation) language or in a combination of regular human language and instrument language. FISINT is also considered as a subset of MASINT (measurement and signature intelligence).

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.
