Foreign instrumentation signals intelligence, FISINT (''F''oreign ''I''nstrumentation ''S''ignature ''INT''elligence) is
intelligence
Intelligence has been defined in many ways: the capacity for abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. It can be described as the a ...
from the interception of foreign electromagnetic emissions associated with the testing and operational deployment of foreign aerospace, surface, and subsurface systems.

/ref> Since it deals with signals that have communicational content, it is a subset of Communications Intelligence (COMINT), which, in turn, is a subset of SIGINT
Signals intelligence (SIGINT) is intelligence-gathering by interception of '' signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication ...
. Unlike general COMINT signals, the content of FISINT signals is not in regular human language, but rather in machine to machine Machine to machine (M2M) is direct communication between devices using any communications channel, including wired and wireless.
Machine to machine communication can include industrial instrumentation, enabling a sensor or meter to communicate th ...

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 UAV
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller ...

*Command signals used in teleoperation
Teleoperation (or remote operation) indicates operation of a system or machine at a distance. It is similar in meaning to the phrase "remote control" but is usually encountered in research, academia and technology. It is most commonly associa ...

Telecommunication
In telecommunication
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than tha ...
, the term FISINT has the following meanings:
1. Intelligence information
Information is an abstract concept that refers to that which has the power to inform. At the most fundamental level information pertains to the interpretation of that which may be sensed. Any natural process that is not completely random, ...
